Very nice, except the t700 800 mix, and to a lesser extent, weight.
How much do they sell their frames for usually?
This frame in a lighter / stiffer version with t800/1000 could be pretty amazing.

Difficult to say by comparing the 3D rendering with real pictures, but is Speeder Cycling the OEM of the Tavelo Arow frame?

geometry table is a bit different, seatpost clamp is different, and i think the tavelo frame is supposed to be significantly lighter.

Beyond that, they do look very similar...

Seems nice. Geometry and everything seems like a pretty conservative design, but thats not a bad thing. I do like the shape of the frame as it feels like a blend between the Tavelo Attack and Arow. I also think its an Adapt design. Maybe this one: https://www.facebook.com/photo/?fbid=841101518026184&set=a.227485472721128
 

Speeder seems to get pretty good reviews on here and the SC-ADV09 Bikepacking / Gravel fork is used by quite a few higher end builder as the lower cost fork option offered alongside Enve.

Wow ... 2 frames in one week with a 57/58 with head angle below 73deg (other being Incolor).  Maybe the oil tanker is finally beginning to turn.  Not keen on the low BB drop tho.

How does this effect handling? Both head tube and seat tube angles still confuse me.

Slacker head tube angles typically make for a less responsive bike; but this isnt a good or bad thing since the question is whether or not the overall design is balanced in terms of feedback to actual turning action. One of the concrete benefits of the slacker HT angle is increased front-center and wheelbase for larger riders without increasing reach. Because of current forward trend in bike fitting this has meant that in turns there is too much front weight bias giving bikes a tendency step out.

My opinion would be that they should just increase reach by 2-3% across sizes and call it a day rather than slack out the HT angles, but that creates fit problems for many riders and then you are fighting decades of bike fitting "science" and aesthetic.

bolded part is all industry marketing mumbo jumbo.  second part is true, but the main thing is about reducing deflection of the front wheel due to riding surface, wind, or manhandling the bike at high power out of the saddle and increasing stability at speed.  taller, heavier riders need this more, not less than smaller riders.

increasing reach (and thus FC) will only increase stability a bit - as it'll be a smaller amount and head angles would still be far too steep.

from a fit, bike handling and geometry perspective there is absolutely no reason for larger frames to have  steeper head angles.  whilst there's plenty for them to have slacker head angles.  the status quo is purely about package size.

also any further increases in reach are going to need increases in seat angle - they're already far too slack in larger sizes.

No, the bolded part is physics. Of course you can change other parts to the design to offset it (like lowering the rider). Fit and physics are often at odds in bike designs yet dependent on each other. Its a pretty hard thing to get right.

Just put in an order for the SC-R55D after a dozen emails with questions and requests :) Communication with Justin is always smooth and he usually replies within a day (if not an hour or two), though I feel bad about bothering him for a single frame.

I think this frameset looks really good. Similar to the Tavelo Arow, but some differences in shaping (look at the TT-HT junction), plus this frameset has SRAM UDH, a round steerer (much preferred from a safety perspective), concealed dropout holes. Compared to the older SC-R52D model, I think the fork crown and seatstay junction shaping is much better, as well as the deeper-profile fork legs.

I'm buying this frame for the aero upgrade -- I won a few cat 3 road races this year on a heavy round-tube aluminum gravel frame, but it will be harder to continue with it at the Pro/1/2 level. Aero-wise, I think the SC-R55D is probably decent enough. Looking through the Tour Magazine wind tunnel tests, the similar Wilier Filante SLR tests around 210w @ 45kph with Zipp 404 wheels. For comparison, the fastest road bike is the Simplon Pride II, basically a TT frame, and it's at 202w with the same wheels. Supersix Gen 4 and SL7/SL8 are somewhere in between the two. Comparing the SC-R55D to the Filante, the fork legs are deeper, the seatpost appears narrower, the seatstays attach lower, and the fork-HT transition looks more modern. So aero performance is probably on par with the SL8, at the cost of 100g or whatever, which I don't care about.

I was actually planning on buying a Supersix Gen 4, but after trying out a 58cm model, my thighs rub against the top tube. And I think this is a problem I will have with most aero bikes with wide, high top tubes. I could size down, but then that decreases the front-center too much, which isn't ideal for handling at my height. So I settled on the SC-R55D size 535, which has a lower top tube, and front-center almost identical to the Supersix 58cm at 606mm. The downside there is that the stack is pretty low, so I might need to use a number of spacers, but I'm thinking of using an up-angled stem instead (i.e. the Simplon Pride / Cervelo S5 / TT bike strategy).

The only real downside is BB86. Not ideal for DUB of course. I'll be measuring it with a bore mic. Worst case, buy a 40.98mm reamer ($150) and/or BBInfinite bottom bracket ($200) and it's still a good deal I think.

Oh and the shaping of FSA ACR spacers is slightly annoying. Spacers are on the leading edge of the bike and it seems like low-hanging aero fruit to make it airfoil shaped like the SL7/SL8 rather than a rounded rectangle. I'll either try to print something, or maybe try using a Deda DCR upper headset instead, as the shaping is a bit better.

Unfortunately, custom paint isn't available for a single frame. So I'm getting it RTP (ready-to-paint). Going to do spray.bike, which might be a pain in the cold of ~November, but I'll figure something out.

Prices (USD): $660 frameset (including seatpost), $30 headset, $20 thru-axles, $50 additional zero-offset seatpost, $172 shipping + paypal

Thru-axle dimensions:
Frame 164mm M12*P1.0*L18
Fork 120mm M12*P1.5*L12

Just want to add, my experience with Speeder has been nothing but stellar. Ordered a whole bunch of handlebars and bottle cages from Justin for a set of team race bikes and everything turned out 100% perfecto. Wouldn't hesitate to recommend in a heartbeat.

I suspect if this frame was out when we bought our samples, this one may have been chosen or at least shortlisted. Looking forward to hearing your detailed user experience.

Ah last time I’ve talked to him he said ready in September and he’ll let me know.
I’m currently riding a sc49d and a propel and thought about replacing the sc49d… hmhmhmh…
Interesting to hear about the custom paint. So that’s the matte carbon version then?

RTP is raw carbon*. Matte is usually a clear coat, at least. He also offered glossy (see SC-R52D thread for examples).

I might just ride it raw until spring, I'm pretty sure there isn't a risk of UV damaging the resin in that time frame.

*although apparently if you buy an S-Works SL8 RTP, it actually has a thin clear coat, which isn't actually "ready-to-paint", but rather just the lightest finish possible to satisfy weight weenies

Hey Hendie, super cool build, thank you for sharing! AFAIK you're the first person on the english-speaking internet to report building up one of these frames. I was wondering if you'd be willing to share some more info/photos with us, since there isn't a whole lot on Speeder's website. In particular, I'm interested in a head-on view of the fork + head-tube; Speeder's website doesn't have any photos from this angle, even though it's a really crucial area for aerodynamics. I'm also interested in some views of the surface. It looks like you have the matte black finish? Is it that the carbon is clear-coated over, or is it an opaque black paint that covers the carbon, as it appears on Speeder's website? Also, would you also be willing to share any info like build specs and/or frame and fork weights? 7.05kg is mega-lightweight for an aero-disc build, especially with those wheels; I'd be really interested to hear what went into your build.

Sorry for the delay.

I will get to the details.

Firstly, with the same wheels the bike has gained weight, it is 7.125 kg now.  Made some quality of life adds - adding 70g of weight was shockingly easy to do.

The frame weighed 900 grams with paint, the UDH, and the FD hanger.  The finish is very nice but there were oddities, such as the BB was 40.5mm, and compared to a Light Carbon frame I have the disk brake fittings weren't faced as well.

Components: Dura-ace, with a Riro carbon crankset, 50/34 chain rings, Favero assiomo uno power meter pedals, Selle Italia SLR saddle, Onirii 160mm Rotors front and back, Avian Canary 34 width handlebars, Light Carbon Wheels (68mm depth), YBN Chain, Conti GP 5000 TLR, and TPU tubes.

Wheels are here, they are excellent: https://www.lightcarbon.com/lightcarbon-super-light-c67db-undulating-rim-depth-carbon-spoke-road-wheels_p232.html

The build went really smooth other than mistakes I made, I am new to modern bikes and so I had to redo a lot of things.

Note - it comes with a 7 by 7 seat post clamp.  Ask for the 7 by 9 if you need it.

Justin from Speeder was excellent, straight forward and accurate, maybe too direct for Canadian living in Wisconsin.

Another post will come in a few minutes with more pics.

Thanks for the photos and information. It looks pretty good. Fork blades are nice and thin. It's not the most modern design -- the seatstays could be dropped far more with the seatstay-seat tube junction drafting right behind the ST water bottle (Supersix). The HT-TT junction ridge on the side is a bit unsightly. The seatpost looks a bit wider than I expected. The bottle cage mounts looks like they could both be ~1cm lower, unless those particular bottle cages sit unusually high. But ultimately it's still the best-looking aero frame I've found under $1000 USD.

How did you resolve the BB issue? Are you sure it was 40.5mm, because that's really bad. I think when people talk about undersized BBs they're talking 0.05mm, maybe 0.20mm at worst below the ideal 40.98mm. But almost 0.5mm below is quite something, I'm not even sure it would be ok to take off that much with a reamer in one go? Might be best to go at it with a flap wheel first, then finish with a reamer.

With a BB I may have measured it incorrectly. Because the press fit bottom bracket fit really well. No excessive noise during the install. It seems to fit like a glove.

I don't pretend to be an engineer. I measured it because I've seen engineers on YouTube measure it.

I ordered the spacers aftermarket. So they weren't intended to fit perfectly. Especially the wide ones.

Adapt calls it the FM55 (http://www.adapt-bikes.com/Products-detail?product_id=100) (see: three more 3D renderings). Looks identical except Adapt says theirs has T47, which I don't think is possible without an entirely different frame mold, considering it's bigger than BB86. Or it's just a listing error.

I ordered this frame recently and hopefully will receive it mid November. 
My plan is to fit 30mm tires on 26mm internal width rims so will probably end up around 33-34mm. Hopefully they'll fit. I'll report back once I give it a try

Hi Hendie, thanks for pics and build details

I'm goind to pull the trigger for this frameset.
The only thing makes me hesitating is tire clearance.
My go-to wheelset at this moment is reserve 52/63 which has 35mm front, 34mm rear.
32c tires on them, expect almost identical to external rim width.

Can you give me a favor to measure how tight space between seatstays and chainstays in you 28c tires?

Got my frame size 51

Took about a month for it to be shipped and 20 days for shipping, eu tax prepaid

On first look everything seems good, mounts are faced, no rough bearing seats, bb is faced and inside seems smooth
Only the headtube to downtube juction has something yellow? on the inside of the frame not sure what that is, everything else is smooth.

Was expecting the frame to be a bit lighter but its not too bad.

Weights:
Frame with rear and front derailleur hanger and bottlecage bolts: 930g
Fork uncut: 397g
Seatpost(0mm offset) with saddle clamp: 178g

Thru axles: 73g
UDH: 28g

Will post after i build the bike, still waiting for farsports hypers to be shipped.

A bit of an oversight on my part, deda super box stem only allows 2 brake cables and 1 di2 cable, i had in mind to run 2 cables to the junction in downtube and then to battery, will probably file the stem a bit to make space for 2 di2 cables, should be fine i guess?

Wow, that does look good, and given the rep Speeder has built, mainly from their forks, it sure looks like it holds up. Honestly, the exterior also looks really clean too. Really curious to hear how cleanly it builds up.

Apparently UV resistance isn't a problem. I asked the question a while back, the answer was that the pre preg resin they use these days is already uv resistant, so the matrix that creates the frame is impervious to UV, so what you put on top doesn't matter. This came from a boutique shop that sells raw carbon fiber parts. So even raw carbon is fine they say.

I have schwalbe pro one 30mm on 26mm internal rims. They measure 33mm. Fork is super wide can probably take 40mm, same as seatstays. Chainstays are the narrowest point but there's still a bit of room. I think 35 should fit.

Weight with pedals and bottle cages is 7.7kg which is not the lightest but considering the size and a very deep rims it's not too bad.

Received my SC-R55D a few days ago. Almost 2 months from the order to receiving it at my door. Shipping was only a few days (Fedex International Priority).

Size 535 (more like a 56-58cm).

This is my first carbon bike, I'm not sure what's normal and what isn't.

NOTE I specifically requested it to be unpainted. So, naturally it looks rougher than one you might receive with the standard matte clear coat. Don't judge it too much based on the unfinished appearance. I'll disassemble and paint it in the spring.

BB Shell
I measured the BB with a bore gauge, 6 measurements per side and averaged.
DS: 40.97mm
NDS: 41.02mm
Could be better, could be (far) worse, I think the ideal is like 40.98mm-41.00mm.
DS should be fine, NDS I might use a bit of Loctite 641 for good measure, but will see how it feels first.

Notes/Issues

Aero
Random dimensions for unscientific aero weenie comparisons:

As I might've mentioned earlier, I'm doing a weird setup with a +17 deg stem to approximate the simplon/cervelo/bianchi/colnago thing and to get enough stack for my tall self. Then I'll design a fairing that encloses the stem/spacers/cables to make it sleeker and more aero. Hoping to finish it up by mid-January and have it ready for spring racing.
Title: Re: Speeder Cycling SC-R55D
Post by: Sakizashi on December 14, 2024, 05:37:54 PM
Wow. Thanks for the detailed pictures. Overall, I think it looks pretty good--its a bit i interesting that this frame seems to have avoided many of the same issues that the Tavelo ones had at launch.

Regarding the headset gap. Some of this will close when you torque it up, but its pretty standard with the FSA setup and tighter than many brands like Trek. I don't know what the quality is of those headset bearings, but I suggest swapping them out for an FSA one to ensure you get bearings that have a good seal since most brands have done away with seals other than the ones on the bearings. I go back and forth regarding how much I like the FSA headset design. On the one hand, it is nicely compact, but on the other, the Deda, Token/Enve, and the new specialized design achieve more consistency in dimensions. The good news is that you should be able to fit most of these other systems if you want.

Good luck with the build!

Frameset showed up today. Very well packaged, carbon looks great. Nothing raising any red flags internally. One of the threaded inserts on the fork for the brake mount does appear to be sitting below flush. Not sure if that will be an issue, as I don’t have any components handy to try it out. Everything is now masked, and I’m aiming to hammer out the paint asap

Just had a first ride outside, frame seems good, much more comfortable than my previous bike, although it could also be the wheels and tires, since 28mm tires when inflated are 30mm because of the 24mm internal width

Issues i had building the bike.
The front thru axle was too long, so when i tighten it all the way the wheel was wobbly, so i put a 2mm spacer for now until i get new axle.
Brake mounts are faced but when i mounted the calipers i couldnt get discs not to rub in any position, i guess they are not parallel to the disc, i guess rubbing will stop after i use them for a bit, but i will go get the mounts faced.

Weight without the clip on aero bars is 7.4kg(pedals, bottle cages, garmin mount included)

Photos (36)
https://imgur.com/a/XSRoWzD


Weighs 7.5kg / 16.5lb with pedals.

Unholy mix of 11spd di2 ultegra rd, dura ace fd, grx shifters, and sram red crank with quarq pm.

Light Bicycle WR65 wheels, latex tubes, GP5000 28mm

Bars are Speeder SC-RH01 37/42cm. I've been using them for a year now and they're amazing. Perfect amount of flare, well made, carbon is super thick near the clamp, just the right amount of flex for me.

+17deg zipp stem ;) a bit unsightly with the old di2 junction box and e-tube wires, might switch it out for the less-old bar-end type.

Ryet 3d-printed/carbon saddle (Pro Stealth shape)

ZRace XG calipers

Build notes:

Ride notes: Not much to say really, it's a road bike. Compared to a modern MTB with 65deg HT, they're basically all the same ;D Reasonably comfortable...there's definitely some flex in the seatpost which is nice, and aero handlebars always help too. The only other cantilever on the bike is the fork, but all disc brake forks are pretty stiff.

Title: Re: Speeder Cycling SC-R55D
Post by: precision6625 on January 26, 2025, 09:27:32 AM
Question: why the angled stem and not go up a size? Is it handling, looks,...?
I think I explained a bit in an earlier post, but the main reason is that I want the top tube to be as low as possible because my knees/inner thighs often rub it. I chose this frame because the size 535 has a reasonably low top tube, yet still has a front-center that would typically be found on a 58cm+ (606mm), which is kinda important at my height for descending stability, and also ensures no toe overlap due to my forward cleat position.
Second, it gives me more options -- I can flip the stem easily for a 1hr crit and get an aggressive position. But for anything longer, I think the higher position is faster, especially on climbs (see: arnepeters95 on instagram, I agree with everything he says).
Third, there's a bit more aero potential in theory -- kinda like what the simplon pride ii, cervelo s5, colnago y1rs, bianchi oltre rc, and all tt/tri bikes are doing. Because a head tube is always going to be wider than a stem since it contains the steerer/bearings/cables -- so why not replace that frame stack with stem stack? Of course, a round +17deg stem isn't very aero either, so eventually I want to surround the whole thing with a printed fairing, which should improve the looks as well.

Put about 5000km on this frame, maybe about 2000 outside, 3000 on trainer

Had a minor fall so i had to replace derailleur hanger and pulley cage, bike is fast, dont feel like the frame is holding me back.
I do notice its a bit harsher on the front than any previous bike i had, not sure if its fork, handlebars or whatever else, but its not the end of the world

Rustoleum Blue Cosmos for the color, and some spraymax 2k clear coat for protection.  Also hit the bottle cages with the color shift paint for more speed points.

It's not perfect, but certainly looks good from a few feet back.  Bike is currently hung up for the next couple weeks while 4iiii puts a power meter on the crank.  Really looking forward to getting that back and racing this bike.  Still need to snag some deeper wheels at some point...  Just gotta let the wife forget about the costs first

I only did a quick ride around the block with it, but it feels damn good. Can't wait to do a real ride with it.

Speeder did the paint job.

I also ordered it. How long did it take to receive it ?

From placing the order to receiving the frame, it took about 5 weeks. It was right after Chinese New Year, so they may have been catching up on other orders as well.

Interesting! They refused to do any point for me, but were OK with changing finish (to matte gloss) and adding decals. My frame also took quite long to finish compared to yours, so I guess you have jumped on a "big batch for some brand is coming" wagon.

Still waiting for my frame to arrive but I can still adhere to my schedule before racing season.

What tightening torques did you use for everything ?

I read 10 N.m for the seat post but it looks a lot.

I want to say it was 6-8 N-m.  My clamp has small teeth on it, and it didn't take much to make it stay put.

Thanks. I am thinking to those torques :

Expandeur plug : 5 Nm
Seatpost clamp : 6,5 Nm
Rail saddle : Front 3,1 Nm and rear 4,5 Nm
Thru axle : 11 Nm
Rear derailleur hanger : 4,5 Nm
Stem bolts : 4,5 Nm

What do you think ?
Title: Re: Speeder Cycling SC-R55D
Post by: mudfisher on April 08, 2025, 01:15:06 PM
I did these:
Expandeur plug: 5
Seatpost clamp: 8
Rail saddle, Front and Rear: 4
Thru axle: 10
Rear derailleur hanger: 5
Stem bolts: 5

I rode exactly twice and nothing slipped. The seatpost torque range of 8-10 is pretty high, but since it's written on the clamp, the seatpost must be designed to handle it, right? [crosssing fingers]

It is the first time that I see a such high torque for the seatpost. Thanks to be the tester ;).

Crashed on my speeder today at a local crit.


Only damage to the frame is at the buttom of the chainstays. I am a bit in doubt if I can ride with this or it is only cosmetics.


Frame was flying until i went too fast in a wet corner.

Seems only a cosmetic damage, did u do the coin test? if you have a local mechanic will probably be better to ask them or to SC

Just about ready to take on a maiden (outside) voyage!  Still playing with painting the bottle cages the same as the frame. There’s some small things to add still, but it’s currently 16.0 lbs, or something.something kg.

what's the size of your frame?

Post by: Bowen1911 on May 07, 2025, 03:43:46 PM
Lol, you went from silly shallow to silly deep! Can your rims do a Pokemon thing and combine into the average of the 2 depths?
Be careful with such rims in the mountains. Cornering on that is awful, and if the weather doesnt cooperate, you will get thrown around like crazy. In a downhill + curve + bad wind shenanigans... best of luck!

I live in a pretty flat area, and these wheels are pretty much only going to be used in crits and flat races.  My normal rides average only 500 ft of elevation per 10 miles tops.  The race this Saturday is a circuit - rolling gentle uphill into a 90 second long wall (9% average), followed by a straight DH for the next couple miles.  Flattens out and gets back to the rolling uphill again.  No wind forecasted.  I'm anticipating the straight descent to be pretty dang fast.  I'll take both wheelsets and decide what to race after a pre-ride on friday.  First race on the Speeder!

Maybe I can find someone with a 404 front that wants to trade and wind up with the 606 combo...  Time to talk to the triathlon folks!  Or just look to trade/sell and get some 50mm wheels.  But for $400, I couldn't pass it up.

The test ride last night was pretty windy, and it was nowhere near as bad as I anticipated.  Of course, the nice shallow Reynolds gravel wheelset will be my go-to when there's lots of hills to be climbed.

Here is my review :

1) Communication

The messages were by mail only. Sometimes Justin answered within few hours but sometimes It was two or three days. I think that He is very busy. It is less easy to message him than some others sellers who use WhatsApp. However He answered to everything.

2) Production/shipping time

Production time : 27 days
Shipping time : 17 days

The package was well protected but a little damaged. It was not the fault of Speeder Cycling but the fault of the shipping company. There was a little problem with the box but Justin solved the problem quickly. So +1 for his help.

3) Quality of the frame

Inside was so smooth. The paint and clearcoat look very nice. Calipers were faced, no excess painting, same for the BB. Perfect bearing seats. It looks like a very high quality frame. To be honest, I was impress by the quality.

4) Accessories

Spacers (FSA like) are also nice. There is a Di2 battery holder which is nice.

5) Handlebar

I chose the 370 mm handlebar which is on their SC-R55D website. This handlebar is very stiff and inspires trust, no flex even during sprinting.

6) Build

Everything was perfect. I aligned the break caliper in less than 5 minutes (for both). I installed the BB86 pressfit without any problem (thanks to @Serge for the advice of use Liqui Moly Grease). It seems that the handlebar can handle mechanic groupset.


7) Ride

I installed the Ultegra Di2 groupset with the Tagoola Wheels. I won't make a review of the Ultegra because everybody know it :D. For a review of the wheels (I really like them), you can check the other topic.
The frame develop confidence. It is fast and confortable. My longest ride is only 60 km but I can not wait to make longer rides.
Very stable above 60 km/h, I don't have any problem to climb. When I sprint (and thanks to the combo frame / Tagoola wheels / Ultegra) at 1000 W or a little more, there is no disc rubbing.

8) Conclusion

I strongly recommand Speeder Cycling for the quality of the frame. You will not be disappointed. The frame has nothing to envy of a Giant Propel for exemple.

It is not written Speciali*ed or Fac*or on the frame but It will be as fast or faster :).

Since I have a little over 2,000 km on the bike, I thought I’d do a short update.

I'm a little conflicted about the bike, but it has nothing to do with any problems with the bike itself—rather, it's about the bike it's intended to replace.
I built it to replace my Rose Reveal endurance bike, as I wanted something that looked faster and cooler so I could show off my race rig in front of my mates on a coffee ride and try a more aggressive position. Since I don’t race, actual performance and aerodynamics make little difference to me. I was mostly going for looks, weight, and fit.

The bike is awesome. Frame quality is really good—it's stiff, and it’s the lightest bike I’ve ever owned (currently 7.3 kg ready to ride, with pedals and Garmin mount, in the largest size). So far, so good.

The cracks are starting to show, however, when I switch back to my old bike for some rides. After riding exclusively on the Speeder for a few months, it's instantly clear how much better the Rose is—at least for me.
Comfort is just a night-and-day difference. I wouldn’t say the Speeder is necessarily uncomfortable—I'm pretty happy with my position (even though I still struggle with saddle choice)—but my old bike is just on another level.
I don’t usually notice things like “compliance” or “rolling resistance,” but the Rose just floats over rough surfaces in comparison. I have the same tires set up tubeless on both, at the same pressure. I also used the same saddle. So the difference really comes down to frame and seatpost compliance.
Frankly, the Rose has a gimmicky, super-flexible seatpost which—until now—I thought didn’t make much difference. But the front-end comfort is also superior on the Rose, so it's not just the seatpost.

I initially planned to sell my endurance bike as soon as the new build was finished...
But now I have to keep both bikes  ;D

your post is clearly on spot of what i usually see. people want fast looking bikes, pro, long stems etc etc. But for most of us, endurance frames still rock a lot. FM202, FM1136, etc are great choice for this.

Thanks for sharing your experience. I went on geometrygeeks.bike to compare both bikes, and the geometry is so different i'm actually lost, which tells me you dont belong on a race bike, just like most people, and it's absolutely fine.
Also, that Rose Reveal looks really nice, actually!
Given that Rose is a catalogue buyer of chinese frames, and that Speeder is a revered OEM manufacturer for companies like Rose, i really doubt that Rose bikes are intrinsically better than Speeder, but it does sound like you found a geometry & frame that work for you, and that's great.
If you dont care about extra speed and ride bad roads, i'd consider selling the speeder, because comfort really does matter. I sold my giant propel for that very reason.
What crankset and calipers are you using? they both look cool.

I'll add my two cents here.

I have ridden a speeder rc48d / winspace slc 2.0 and it was the least compliant bike carbon bike I have ridden.
Currently on a Tarmac SL7 and it's a world of difference same wheels/tire combination.

I have no clue about SC-R55D as I never rode one but yes the R48D was not what I would associate with comfort however it did have some nice traits - great sensation of power transfer/planted on descents and cornering.

And I would definitely put 30C tires the R48D has a 28C clearance so that's what I had on.

I don't find my bike harsh at all.  Currently running 30 or 32c tires depending on which wheelset it the flavor of the wind.  Took a hot minute to track down all the creaking. Turned out I forgot to carbon grip the seatpost....  Oops.

Did a century a week and a half ago, put 1500 watts out last week, and have even gone down a few gravel roads. Only on the gravel did my Addict Gravel feel better.  Other than that, I've been quite pleased.  One day I'll hop on a "real" bike and get the full comparison.

I would not say the bike is harsh, I was pretty happy with it until I rode my endurance bike again and I think that Rose is just on another level it terms of comfort. It spoiled me

What crankset and calipers are you using? they both look cool.

Geo indeed looks vastly different but my position is almost identical between the two bikes. Within a couple of mm.
I have no doubts that Rose buys their frames in the far east but they are not your regular "just paint the OEM frame" kind of brand. Most of their bike have really unique features and I'm pretty sure that at a very least they have R&D in Germany and they design their own frames
Crankset is Leese, here's the link: https://vi.aliexpress.com/item/1005008541602018.html (https://vi.aliexpress.com/item/1005008541602018.html) I'm very happy with it, I paid something like 150$ with the spider during one of the sales. I initially received the spider that was a little wobbly but the seller have sent me the replacement really quickly and have 0 problems since.
Calipers are ZRace XG. They are definitely better than the original ltwoo and super light (don't remember the exact weight but they are lighter than the dura ace calipers) but I had a hard time bleeding these. None of the adapter from my bleed kit fit the bleed port on these calipers so I had to get creative.

I think my original post turned out as overly negative but just to clarify I really love the bike. I just shared my perspective as someone new to race bikes. I will definitely keep the bike. Thinking about doing head to head tests against the Rose once I get my hands on some powermeter pedals.

For what it's worth, I've been riding my Speeder for about two months now and I don't find it uncomfortable at all (including a recent 205K ride). I'm running 30mm tubeless at 65-70 psi, but it feels like I could go lower. For comparison, in the last 15 years, I have ridden mostly a Dengfu R06, Giant TCR and a CAAD8.

If you only had the Speeder, you wouldn't know that Rose would be so much more comfortable, and you'd probably find the Speeder to be plenty comfortable :)

Yep, that was exactly the case. I was exclusively using speeder as my road bike this season and was completely satisfied with a ride quality but one day I accidently reset my ltwoo derailleurs before the ride and didn't have time to set it up so I took Rose and that was my "holy shit" moment.

I love this bike (only 1000 km ans max ride of 100 km) with 28 mm tire which measure 30 mm on my rim. I don't find him uncomfortable but my roads are almost always in good condition.

Even in face wind I enjoy to ride it.

I'd be curious to see how the R55D feels against my Tavelo Arow if they are indeed from the same factory.

The Arow isn't harsh at all especially with 30c tubeless tires. But I also have high tolerance for stiff bikes.

Okay, so it's time to say a few words about my plan for this frameset.

I am currently riding my first road bike Bianchi Sprint size 53 on 105 Di2, which I bought in July 2024 - due to the huge saddle to bar drop (125mm) and the search for comfort, I plan to sell it and spend the entire amount on this project.

I have pre-ordered a Speeder SC-R55D frame in size 510 in white gloss and 50/60mm speeder wheels with wide rims.

I plan to install Ultegra Di2 groupset on the bike, but I'm still considering changing the original crankset to spider powermeter (Sigeyi/XCADEY), carbon cranks (Elilee?) and Pass Quest/Stone chainrings.

Below I paste the project table, my current bike and the speeder rim profile.

EDIT: As it is my first build im open for any suggestions and tips!

Rose x lite looks quite similar.
My friend has one, he'll measure the dimensions and I'll compare it to my speeder

Coming back with the measurements. Rose Xlite seatpost is 32.6x22.6mm and speeder has 34x22mm so close but not quite the same

I got the 480, which is a little smaller than I am used to and installed a 130 mm stem. Its wheel base is 7 cm shorter than my previous bike, and it is just as very reactive. I can't notice the difference at all. The Speeder responds super quickly, and it's been perfectly fine for crits.

Why is it the only size 58 I'm finding with that long of a wheelbase? Most are around 20-15mm shorter. With my limited knowledge the 1020 just seems longer than what I'm finding on other bikes geared for racing. I'm sure it feels solid. How does the wheelbase number make you feel?

Which bike do you compare it to?
When I compare to the rose xlite, which this frame reminds me of, the geo is somewhere between sizes 59 and 61 and the wheelbase for these sizes are 1013 and 1027 so speeder lands right in the middle.

Looking at other racing bikes, the wheelbase does seem a bit long. Is it offset with a steep head tube angle and less rake?

A 59 and 61 are much 'larger' sizes. An SL8 and Factor Ostro Vam in size 58 has a wb of 1006. Cannondale SSE 1007. Size L(57.2)Canyon Aeroad is 1001. Y1Rs is around 1000. Cervelo S5 999.

I don't know what you mean by 'much larger sizes'. In the speeder geo table the largest size is 560, the one that assume you refer to as 58. But that 560 is just a length of a seat tube. When you look at the other numbers like top tube and reach, this size is something I would consider an XL. I am 193cm tall and this size is spot on for me(maybe a touch smaller than what I usually ride) but I'm probably on the higher end of the height range for this frame.

Hi Guys,
Long time lurker here. Based on what I read on the forum, several months ago ordered my first frame, the SC-R55D.
Coming from a rim brake SS EVO, I had high hopes and wanted something better than the Aliexpress frames.

Finally received the frame yesterday and I am not sure some things are acceptable.
1. There is a weird peeling near the front derailleur mounts(img_7247).
2. Bottom bracket, delamination(img_7243). This is the most worrying for me. Can it be damage from transport or it left the factory like this ? From what I know once it starts delaminating it is risky to ride, especially in the BB area.
3. Top of headtube, damage on the rim of the tube and on the bearing seat.
4. Seat tube, cosmetic damage on the rim of the hole and what looks like a lot of filler on the inside of the seat tube.
5. No di2 battery hanger included but 3 screws on the downtube. Where should I mount the battery, seatpost ?

I expected a perfect frame for the price but now I am a bit lost as it is my first frame buy.
Could someone please advise if these things are "normal" and acceptable to ride ? pictures attached

It looks like a totally different frame from what I had. The finish of my frame is way better and perfect (you can have a look at some pictures on this topic). It is even above of some major western brands.

I also received with the frame a Di2 battery holder. It is a small piece which looks like a seatpost clamp.

Title: Re: Speeder Cycling SC-R55D
Post by: Mircenzo on July 09, 2025, 09:58:00 AM
Maybe it's the pictures, but i'm not seeing what you're seeing.
1. FD mount. Looks like the paint just peeled off. Probably they masked the bolts, and the paint peeled off when they removed the masking tape. I wouldnt worry. Potentially, put some nail polish where the paint is missing. But that looks purely cosmetic, and you'll have the FD mounted there anyway.
2. i dont see delamination. Where do you see that?
3. dry fit a bearing and see if it fits properly. That imperfection isn't ideal, but i think it's completely harmless. Tolerances are much more important (does it fit without wobbling / rocking).
4. if we're looking at the same imperfection, then it's completely harmless to the point i probably wouldn't notice it.

If it were a spaceship, these things would matter. It's a bike frame. The internals on your pictures actually look super clean, which seems much more important.

Probably I stress too much as it is my first chiner but also my life depends on this thing so I want to be sure it is safe.
It is also for this reason I went with Speeder instead of other cheaper brands.
 
1. The box arrived damaged in the center, seems there was a hit on the FD mount. Upon additional check I can see a small bump on the inside of the seat-tube. Justin confirmed it does not leave the factory like that.
2. See attached photo.
3 + 4 the bearing and the seatpost fit well, so it is mainly cosmetic but still not on the Speeder level that I saw from other members.

Both my TanTan and Yishun/LC frames, which i paid for myself, didn't have any of those flaws. Yikes. Thankfully those flaws should not have no affect on safety or riding experience if the tolerances are correct.

Funny how we make concessions for brands we like and scrutinize other brands with impunity if we don't. Personally I would be disappointed in those flaws considering how much Speeder gets propped up around here. But I wouldn't complain and contact Speeder about it.

I'm French, complaining for me is an art de vivre.
But even on these pictures i dont understand what i'm looking at.
By all means, if the BB is indeed delaminating, speak w Justin, but if you provide him w evidence, please do better than what you shared so far, because i dont see the problems you see on these 2 pictures, and it's probably best to hit him first with the best quality evidence you can provide, as opposed to a blurry picture that's a cropped bit of a wider photo.


You're right about the picture quality. Here is a better one.
I am already in discussions with him. He said the engineers will review it this week.

Post by: Mircenzo on July 10, 2025, 05:10:01 AM
Ah, now I see! It does look bad! Let us know what Justin says. I wonder if you couldn't just pull on that flake and shear it off and move on. That piece is probably a fraction of a gram, if the rest of the area is resin infused properly it's probably nothing.

I will not pull on anything at the moment, even if it is a top cosmetic layer.
It does seem a bit odd that Justin needs days to reach to the engineers in the same plant.

In my non-expert opinion there does seem to be poor compaction of the layers in the thicker areas like BB and headset.
Let's see what Justin says.

Title: Re: Speeder Cycling SC-R55D
Post by: Da11as on July 13, 2025, 12:58:50 PM
Think I have enough time spent on the bike to draw intermediate summary about the frame and my experience with Speeder  :)

The communication with Justin was sometimes delayed (got a reply after 4-5 days), but it was always clear, concise and unambiguous. The frame production took longer then I expected, but I also asked for some customization, which is probably uncommon for B2C side of Speeder. I asked for gloss over carbon marble finish for frame+fork and matte for everything else. Everything arrived packed in a foam wrap and bubble packages without any damage.

Now to the frame. From manufacturing point of view everything was pretty much perfect - everything that has to be round is round, seatpost fits perfectly, BB area, HT area, caliper mounts were neatly faced, thru axles fits nice and sturdy. My mechanic's feedback is the same - everything was done very nicely, assembly was problems-free.

Riding quality completely meets my expectation - I wanted a race bike with nice balance between stiffness and compliance with specific geometry that enables my aero position for extended periods of time. It is quite stiff at BB and HT area, seatpost and seat stays absorb bumps well and after long ride on bad roads I don't return home beaten up like on a full-on aero brick.
As for speed and aerodynamics I don't want to do any specific testing but my position resembles my aero tuck on my older CF5 Merida Reacto. I am somewhere around 1-1,5 kmh faster at my steady state long flat tempo efforts (~300-340W@40+kmh). So in no way the bike is slow!
Above in the thread there were concerns regarding the bike maneuverability. I can attest, the bike is more nimble then Light Carbon LCR0X, which has shorter wheelbase. Longer wheelbase is compensated by steeper headtube and generally reminds my above mentioned Reacto.

With the mix of Ultegra and 105 Di2, Bigrock Ti axle cranks, Elite Edge wheels, 2nd gen The one handlebars and last generation ZTTO Ultimate monoblock steel cassette, the bike wights slightly above 7,5 kg in size 535 including pedals, cages, computer and Varia mounts. That being said, if you choose your components with the weight in mind, 6.8 kg build can be achieved quite easily.

I must mention UDH as another cool feature. Within the first week of riding I managed to crash badly and bent my hanger in the process ;D Quite easily, I have found the replacement at my LBS on the very next day.

Overall, I can totally recommend the frame - if it fits your needs and is appealing to the eye, go for it.

Your 48D also has marble finish under the coating or it's plain black? Because I meant marble finish (matte or gloss) as a fine touch to the simple finish.

The cages are Cannondale Gripper with Regrip aero bottles. I choose them over the Trek ones because 1) they are significantly cheaper; 2) opening of the bottles is not stupidly narrow; 3) it is possible to fit standard bottles in the cage.

Well, after about 1300 miles on the speeder, I'm going to be upgrading to a SL8.  Got hit by a car a few weeks ago, and the insurance settlement is buying me a new bike.  No injuries, only carbon damage - Zipp 808 rear toast, frame and bars impacted, but able to ride home. 

I've had zero complaints about the bike, and haven't lined up at a race without someone asking about it.  Justin was also great to work with when purchasing.  Would buy again if/when I'm in the market for another Chinese frame.

Elite also does this finish on some of their wheels. I have a matte version and I do like it but there's a couple of things that annoy me:
 1) some parts of the frame are not raw but painted black. I think they spray paint joints and parts of the frame where carbon looks kinda ugly. I personally would rather have ugly carbon showing that just black paint. It is very obvious and does not look great especially in the direct sunlight when carbon weave reflects it but painted parts remain just black. It looks the worst on the fork where the entire crown and bottom part where the dropouts are connected are painted.
 2) people who see the frame for the first time tend to try to rub or wipe the frame which annoys me a lot  ;D
 3) my girlfriend hated it and keeps remind me how horrible it looks  >:(

I'm coming from an older rim brake model so the majority of my subjective views can be disregarded.
Ordered 12/5/25, sent 23/5/25 and received 29/5/25.
I ordered a size 560, asked Justin if there was any movement on handlebar dimensions re longer stem on the narrowest option. The handlebar was 370/105mm and ordered a 0mm offset seatpost.
Bars weighed 380g.
Frame weighed 908g.
Fork weighed 393g.
Front axle 33g, rear axle 45g. Frame comes with option to purchase without these- would consider as they are fairly heavy options.
170g additional parts- spacers, seat clamp etc.

On arrival frame had a small patch of what seemed like moulding material remaining on the inner aspect of the head tube. This was easy to remove and therefore not pictured.
Bottom bracket used was the SRAM DUB BB86 one, fitted easily and have had no creaks. BB86 is the only real issue with the frame- am expecting the bearings to wear out quickly but up to this point have had no issues. The T47 version seems interesting on this front.
Overall have had no issues with the frame, it's significantly faster than my previous bike and am very satisfied with the purchase.

Certainly won't be apples to apples, but my replacement frame is now on order.

Given the combination of insurance money, '25 model year sale prices, and additional "bro discounts", I maaaaaaaay have splurged for a SWorks SL8...

Looking forward to the comparison between the two!  A friend of mine will be taking the speeder and running it at risk, so I can always hop on them side by side

Fingers crossed none of you get hit by a car, but if you do, I hope you can turn it into a fruitful endeavor.

Can we agree that we changed the carbon layup since the first post? It is now T800/1100 and MJ40 end. And they lowered the weight by 100gs. Size 51 is now 780g. If this is true I think it makes the frame quite a bit more interesting. I wish they did EPS moulding.

Yeah in the sales section it was also referred to as the new layup.

I think it has been this way quite a while ago. My 54 with stock furniture and coating is 916 g, ordered in December.

Considering how clear the frame is from the inside it should be EPS.

The EPs former id dipped in latex.  The EPs/latex form is wrapped with CF. That latex is the bladder which is the inflated.   
Older methods used bladders made of other materials and without a former.  I.e. both use gas pressure to consolidate the plys

I finished my build.

Quality is amazing, i didnt find any suprises.

Three things to look after:
- Shimano pressfit BB went almost without resistance
- One bolt seat clamp is shit (used on offset seatpost) it slipped after few potholes.
- Once i pushed seatpost into frame it was battle to raise the saddle (too tight HT propably)

I very like look and overall handling of the bike - i would buy it once again

Size is 510. Wheels are 60mm with 24mm internal on DT350 hubs with Sapim CX and brass nipples from Justin.

did you put Loctite on seatclamp bolts? And of course, how is the ride feel compared to your previous bike? I am close to buying either this or LCR017D.

I'd get the 55D over the 17D all day, every day.

I'm leaning towards 55D because the geometry seems to fit me and I like the design. 17D's geometry is so confusing and I don't quite like the down tube design. Only thing that making me think twice is that 55D is more expensive than the other one

I ended building with Ultegra Di2 groupset, Pass Stone chainrings, XCADEY spider powermeter and Elilee X310 cranks.

To be honest, i cant feel any difference between that and Bianchi. I switched to 165mm cranks from 170mm and to 30mm tires from 28mm - it feels very smooth, easy and comfortable to ride. I also think that this setup is quicker, but i need to calibrate XCADEY with Kickr trainer first.

I bought crankset because of the look and i cant find any advantages more than that. Cranks are so massive that i hit my ankle twice on sunday. Chainrings are more noisy than 105 Di2 from my previous bike.

I would definitely choose Speeder over LCR (design, geometry).

I have compared both and there are other users on here with direct experience which is highly valuable, but I don't see why one is dated over the other. I would however distinguish between the Velobuild 268 and Long Teng 268, the latter seeming to offer much higher quality. Clearance wise similar, weight wise - the Speeder might have a slightly lighter frame but not fork. The speeder however has more agressive geometry, which didn't work for me.

I have my bike for over a year now and about 8000km. The bike is excellent with a couple of caveats. I've built a lot of chinese frames at this point (2 velobuilds, lightcarbon, spcycle) a this one is above all of them by a huge margin in terms of quality but it's a bit more expensive as well. Ive never owned any of the premium chinese frames so don't really know how it would compare.
some minor problems I've had are clear coat overspray in the headset that i had to clean up and a creaky seatpost. I haven't solved the seatpost problem completely and it keeps coming back. My saddle is set up almost as high as it can go so there's quite a bit of leverage that is contributing to creaking.
Not a huge fan of the handlebar too. Finish quality is fantastic but it's a little heavy in my opinion and a shape does not work for me: drops are too round and I can't find a comfy hand position, also not a fan of a short reach.
I switched from a super comfy endurance bike so the frameset felt quite harsh initially and I could not find a saddle that would work with this geo but this problem was solved since.

TL;DR
Frame is great. would buy again but without a cockpit

I actually bought this toseek handlebar https://pl.aliexpress.com/item/1005009467469501.html (https://pl.aliexpress.com/item/1005009467469501.html) it's the same as a popular kocevlo cockpit but with a slightly different finish which I prefer. It's lighter than the original speeder cockpit and it's less than half the price (got it for 55$ during 11.11 sale). I never bothered to swap it though since I was too lazy to mess with the brake hoses and ended up using this cockpit on my gravel build.
max stem length for it is 120mm but it has 5mm longer reach than the speeder so the effective length is the same for the longest options.

Oh and one more thing about the speeder handlebar that is extremely annoying is that the "stem" part of the cockpit is very thick and the bottom part is angled upwards so when you mount a computer mount it's pointing up. I had to get an adjustable mount but they are all aluminium and heavy https://pl.aliexpress.com/item/1005006157561431.html (https://pl.aliexpress.com/item/1005006157561431.html)

Looks bad tbh. Big shards of carbon not attached to the frame isn't good. The finish quality inside looks rough and bad.
But it's probably the pictures that make it look worse than it is.
I would take a video and send it to the seller.
Stating the obvious, but you can't have large loose shards of carbon in a frame, as these have zero structural integrity. Maybe what you're showing is bag residue or something, but I would reach out to the seller. How's the rest of the frame?

Yeah the photos do make it look a little bit worse than it is, but since it's right where the seat post goes in I'm a little bit more worried with the lack of structure, that and also this not being a cheap frame I was a little bit disappointed....

I did send the photos and this was the reply...
"This is quite common for hand-made carbon fiber frame, it doesn’t affect the assembly and structural strength.
You can go ahead and build it up to ride."

I'm going to try and get endoscope in today or tomorrow and I will share if I get any decent photos from it.
But it seems that the rest is good without imperfections.

But as you can see there's a big line of what seems to be resin and there's 3 or 4 spots where you can see there's some imperfections.
I know it's all based on terrible photos, but what would be your opinion?

There's a small patch (1771420271211.png) that I thought it was resin but was able to touch and it seems to be something else has it's moves around, maybe some carbon fibers or a rest of the bladder.

Rest of the frame looks super clean. As someone completely unqualified, you're probably fine. It's not like you ordered from tantan. Ride it, worst case, it cracks around the seat post, and you then get it replaced, just monitor the area.
I'd email the seller to mention that. saying that you expect them to honour the warranty if that questionable area ends up breaking.
i dont think it makes sense to try and get the frame replaced, it seems unreasonable.

Yeah, I 100% agree with you on that honestly I just wanted Speeder to maybe say something better than just "it's normal".
I will send them a message saying exactly that and will try to build the bike before the weekend!

As an owner of this frame I can't help but to notice this frame being sold under different brands. One of them that I posted a few pages earlier is Parapera atmos.
Now another atmos poped up in my feed on youtube that looked rather curious. It looks like the same SC-R55D frame but in a composite carbon-titanium construction.
I don't know what the claims of the manufacturer about this frames are since all of the videos are in German

What do you think?

That's definitely r55d and there's noghing unusual about it. I'm interested in the composite titanium frame that is also based on the same frame. Just surprised they used an open mold frame for such an expensive project(they sell framesets for 5000 euros) Wonder if they've got the frame from speeder in pieces or just cut the frame and then glued it back together with 3d printed titanium lugs

That's definitely s55d and there's noghing unusual about it. I'm interested in the composite titanium frame that is also based on the same frame. Just surprised they used an open mold frame for such an expensive project(they sell framesets for 5000 euros) Wonder if they've got the frame from speeder in pieces or just cut the frame and then glued it back together with 3d printed titanium lugs
Monocoque frame like this are usually produces in 2 diferent parts, front triangle and rear triangle separated. I'm wondering why to get a monocoque frame, cut the frame and glue 3d printed titanium lugs.... I hope they are not doing it! it would be non sense

i think the naming is really confusing. I believe manufacturers call monocoque a frame that has a monocoque front triangle whilst the read triangle is bonded to it, and the rear triangle also has multiple pieces bonded together. Does not sound very "mono"

@pavlo.k

Do you have some photos of the bike from outside? What saddle height did you set, measured from the bottom bracket?
I'm between sizes 535 and 560, but I prefer the 560; I could ride it without spacers. The longer head tube also looks a bit better.

Edit: You can now also select the type of BB: "BB: Press Fit BB86.5 or T47"

Thanks for the picture.

I'm 1.80m tall, but with an inseam of about 87cm, my legs are a bit longer than usual, and my arms aren't exactly short in proportion to my torso. My saddle height is about 760mm.

Currently, I ride a 2018 TCR Rim Brake in M/L (stack 562, reach 398) with 15mm spacers. So, I would ride the 535 with the Light Carbon cockpit with an 8mm rise and a 110mm stem + 10mm spacers.

I would ride the 560 with a cockpit without rise, a 100mm stem, and no spacers.

The riding position would then be almost identical on all three bikes.

I'm no expert in bikefit and it's just my subjective opinion but think you should go for a smaller frame. Speeder sizes are a little confusing. 560 is a seattube length but the size is more like XL or 59-60 when you compare to other brands. Take Rose Xlite for example, If you look at the geo 560 speeder lands right between 59 and 62 Xlite

Yes, that seems like the better choice.

I'm still waiting for the release of the new Radon Vaillant (German brand) in March. The geometry is quite close to a Supersix Evo. If the price is as low as it has been so far, that will probably be my bike; otherwise, I'll go for the SC-R55D in 535.

I am almost your dimensions (180 cm, ~86 inseam, regular arms) and I have 535 frame with 130 stem and 78 reach handlebars, 10 mm spacer. Coincidentally, I have TCX size ML :)
You may check my bike few pages back. I will change my cockpit to get extra 10 mm but it is mostly to go further down the progressive-agressive fit, if you are on the more traditional side it is fine as it is.

I think you will be fine with 535 setup, 560 will be very long and you get little to no seatpost exposed. I definitely wouldn't put one piece bar yet, just try separate cockpit if you are not settled with the position.

Thanks, buddy. I've actually already seen your bike, I like it quite a bit. Does the glossy finish cost extra?

Yeah, I think 535 is the way to go. This is my second year and I'm slowly getting closer to my optimal position. I currently have a 110mm stem on my TCR. It's pretty much perfect for Zone 2, but for higher efforts in aero tucks, it could be a bit longer.

So the idea of ​​a separate cockpit for now isn't bad either.

Bikefitting is a rabbit hole. Im 178 cm, ~86 inseam and im riding 510 frame with 95 stem (which is way too short for me). Because of heel dropping my saddle height is very low and i can ride that bike with slammed stem.

Finally built the bike up, did battled with the internal cable routing ( but that's on me for wanting to use a mechanical groupset and setting up the brakes reversed the first time).
Haven't been able to do a real ride on it, just around the block but it seems way more comfortable that I was expecting, I'm coming from a Look 586 with Cosmic all carbon wheels.

For the curious ones the bike setup is as follows:

Frame: SC-R55D - BB86.5 - Size 510 (was weighing 900g bare frame :( )
Wheels: Tagoola - Aeroraptor 60/50 (1230g)
Handlebar: Lexon thin line 400/110 (320g)
Seat: Ryet G01 (100g)
Groupset: Shimano 105 - 12 Speed Mechanical
Crankset: Goldix 53-39T chainrings with CRUZBIKE (Titanium axle)
Cassette/Pedals/Chain/BB: Dura-ace (cassette 11-30T)
Disk rotors Shimano (not sure the model)
GPS Bracket: Zrace titanium
Bottles: AhyKa Aerodynamic

Bike as it stands in the photos is 7KG

The objective was to take it to below the 7kg with all, maybe when I move to a 1x I will be able to do it.

I also have these bottles and they are a bit wider than the down tube. still looks good though. If you want to maximize aero look, you can mount the down tube bottle lower (there are 3 bolts on the downtube)
and the bottles would be next to each other with only a small gap. But I found the bottles hard to reach in this setup.

Sorry for the late reply, here you've got the photos
Hope it helps!

Btw did my first ride on the bike, just a small 50km one and first impressions are good, the bike is really comfortable and fast!
Will leave a better review/update once I have more kilometers in it.
Title: Re: Speeder Cycling SC-R55D
Post by: Da11as on May 14, 2026, 05:45:57 AM
I have clocked around 8k kilometers so I guess I can make a follow-up long-term review of my Speeder.

Starting with the caveats:
- saddle clamp bolt position makes it impossible to reach the front bolt with torque wrench and regular head - ended up tightening it by feel
- expander plug provided with the frame is not strong enough to keep handlebars and headset in place - issue solved with buying the longer, better manufactured plug from PRO.

That's pretty much all I've had! No sanding, facing, workarounds and other stuff you may expect from Chinese frame.

The bikes feels great and seems like future-proff allrounder - generous clearance, good geometry, super comfy, quite stiff where it is needed, pretty light and easy to work with. The biggest upgrade from the first setup were wheels and cockpit. I upgraded my older Elites to XMCS 26/33 58mm deep rims with steel spokes and went one size up with the same tires (30F 32R). Wide rims make ride even more comfortable and I will never look back at anything narrower for a road bike. HBR17 handlebars (130x380) from LC were installed mostly to increase re seems like a great upgrade from my 2nd gen The One handlebars (120x380) - 50g lighter, yet stiffer and cheaper. The only thing I don't like is a proprietary computer mount, longer reach could also be beneficial.
I ended up with the final weight of slightly below 7,4 kg with pedals, cages and mounts, which, considering the budget spent and frame size, is great. I will keep the bike for a foreseeable future as I don't see any reason to change it - it is very well made and performs great as a race bike.

PS: the Varia mount suggested by @tgarne fits like a glove - I bet the seatpost is interchangeable with Propel's.

Mine has similar shape and when I try to torque it up to spec, it slips - the angle is not close enough to 90 degree. And it scratches the seatpost too... Anyway, it's not that much of a trouble :)

I’m also not hating on my 48d and it has been great but it’s very stiff.
In the end I was much more satisfied with it than my giant propel. But that may also be due to the fact that I expected a bit more from a frameset that cost 3x more.

Only drawback could’ve been communication with Justin

I did about 13000km on mine and counting. Love the frame
I completely rebuilt it for this season: new wheels, cockpit, 0 offset seatpost, new ltwoo er9 v3 with 4piston calipers, galfer rotors, new cassette, chainrings. Weight with pedals, bottle cages, computer and varia mounts is exactly 7kg
I also recently installed 34c vittoria corsa tires. They measure just under 34mm on my 24mm internal rims and there's plenty of room left. You can probably put 38 in the front. In the rear there's still 4mm of clearance with the 34.

Looking to get this and wondering about geometry. Is their size 450 closer to a size 48 in Cannondale? I plugged them into Bike Insights and this looks like a slightly more aggressive Supersix Evo frame in my size of 48. Would this be right? I'm only 5'5 so can't really go to any smaller size.

I was in the same boat as you, exactly same height and same in seam, I went with the 510 because I wanted to have a slammed cockpit
Looking back if I were to buy again I think I would go for the 480 with a riser handlebar.

If you want you can look at my photos to have an idea of how tall the seat post would be for you on a 510.

During the internal inspection, Sorry - forgot to take photos, so just the text:


To make it clearer - these are very very minor flaws, the mechanic said that most well-known brands have much more major issues

- Definitely not a single shape mold because the back triangle is glued on, but that's completely normal
- The main thing that the mechanic noticed is that the carbon sleeve under the bearings is not the same width everywhere - in the front part it is 1/2 smaller than in the back, but this is only noticeable visually, after assembly I did not notice anything
- In the upper tube there are two glued patches at a distance of ~5 cm from the headset - it is difficult to say why they are needed, perhaps just for better stiffness - so it might be even good


- The frame is clean inside and looks good.

- I can confirm that the frame feels good in my hands, it is stiffer than my Yoeleo R6, maybe like the Supersix Evo Hmod, or maybe better.

 In general, I am very satisfied with the frame. If there is anything new, I will update the post.
