Title: LightCarbon Gravel LCG074-D Micro Suspension Pivot Design
Post by: Hualicopter on August 19, 2025, 06:51:05 PM
https://www.lightcarbon.com/lightcarbon-gravel-frameset-micro-suspension-pivot-design-with-integrated-handlebar_p254.html

Has anyone built up this frame? The microsuspension pivot design is really neat to me, but I am also worried about adding another point of failure or squeakiness. Or if it even makes a big difference in comfort.

I actually ordered one with a custom paint job and it is currently in transit. So did a friend of mine. It's indeed a bit of a gamble whether the pivot will be reliable.

I'll post pictures once the frames arrive and will keep you informed on the build.

Isnt this the same type of pivot the cannondale topstone has? From my understanding, the seattube and the top tube and the seatpost all have to flex in unison to make this work. How many cycles of this flex can the frame take?

In the pictures and videos, the lightcarbon axle loks like it is fitted just outside the seattube cyclinder, whereas the cannondale one is IN the seattube, also the cannondale seattube is almost bent like a bow, but the lightcarbon one looks like a regular seatpost. Would be very interesting to see how it holds up in the real world.

Certainly looks like the same frame, but at the same time some measurements of the geometry is not the same. Look at HT/ST angles. Should put this in geometry calculator and check, one of them is most certainly not correct 😅🫣
If 73.5/71.5 angles give 550mm top tube in sz520, then with 74/71, it should have shorter top tube, since both have same wheelbase measurements.

Ok, I haven't taken the time yet to take proper pictures, but these are the first ones I took after I unpacked the frame.

Can add better ones later. The inside of the frame (bottom bracket and headset area) looks really clean.

Looks awesome. Please let us know what the biggest tire you think could fit in there. Or share pics of what ever tire you are running.  Also, what is inside the pivot point?  Is it bearings or a bushing or elastomer?   Thank you.

Bearings in the pivot point.

 With regards to tire clearance: they say it's max 50mm so that's what I got.

Will post pictures of the build (and real life clearance) but due to my calendar being quite full I think this will be the beginning oktober at the earliest.

The finish looks pretty good. I wish the downtube was wider though. The hatch and the storage looks cramped as compared to the other modern gravel bikes. Please let us know how it rides after you build it. I really want to know how the pivot design feels.

I have a question for you guys in here who know geometry well:

How would you describe the characteristics of this frame?
I am searching for a gravel frame that I will use for everyday riding, but also longer bikepacking and maybe some ultra racing with minimal bikepacking setup.

Kind regards
Title: Re: LightCarbon Gravel LCG074-D Micro Suspension Pivot Design
Post by: bikepacker_dude on September 29, 2025, 04:28:23 AM
Would you say that this frame is more upright than the GR201 (tantan etc) in terms of geometry?
Title: Re: LightCarbon Gravel LCG074-D Micro Suspension Pivot Design
Post by: bikepacker_dude on October 11, 2025, 06:25:54 AM
Alright.
Yesterday I ordered one.
Lightcarbon LCG074S-D
I opted for stem only and not integrated handlebars since I do bikepacking and I want that round tube nest to the stem, to fit aerobars and other stuff for the bikepacking.
I chose Two custom colors, and the SP02 25mm setback seatpost to get a slightly more relaxed position.
Plan is to use this one for "Nordic Chase" which is a 800 km gravel race between Copenhagen (capital of Denmark) and Oslo (capital of Norway) passing through Sweden (my country)

I have a ToSeek carbon gravel handlebar and a Shimano GRX 1x12 setup (40T front, 10-51 back) waiting in my garage.

As we speak there is a wheelset built in the Tagoola factory (50mm deep, 32 internal width) that I hope will be awesome.

The two images are a Lightcarbon picture with a setup similar to mine, and the very design sheet showing my color choice.

How is your build going? Awesome color! I'm very curious about the ride quality because I cant find a review anywhere. Does the mini suspension work? How is the flex in the frame and doesn't it unnecessarily bounce on the asphalt?

Nice! I like purple/pink parts, it's kinda wild.

So many questions :); I'm also eyeing a force xplr AXS 13s groupset, why did you mix it up with Rival, costs? How is the clearance on the chainring (42t?), do you have the wide or standard version? How did the buildup go, any trouble? How is the build quality of the frame? Are the wheels also from Lightcarbon? Love to know how your first ride is and how you feel about stiffness of the frame and ride feel.

Please give feedback on the ride quality, and if that pivot suspension really does work. How much did they charge you for this paint work?
Title: Re: LightCarbon Gravel LCG074-D Micro Suspension Pivot Design
Post by: splintersneaker on October 28, 2025, 01:17:46 AM
Some replies, more info will follow.

Paint job (2 colours) was $180. A friend of mine got the same frame with a chameleon effect (looks even better than mine) and that was $120.

I went for a Rival group, but swapped with Force for weight savings (crank set) or looks (cassette and purple chain).

Build was quite easy. The most fiddly bit was routing the brake hose through the handlebar. I'm not the best at that and don't have proper tools for the job.

Keep in mind that the mandatory spacer to hide the brake haves for the integrated handlebar will raise the stack quite a bit.

I went for a 38t. Plenty of space left, but they spec 42t as the maximum.
SRAM XPLR cranksets are always of the "road wide standard) IIRC.

Quality of the frame is very good. BB and head tube area inside is flawless.

The wheels are from Yishun. Have already had 4 other wheelsets of theirs. Mostly with DT Swiss hubs and Sapim CX Ray spokes but since this is a bit of a "budget" build I chose their default setup: unbranded hubs and Pillar spokes.

Yishun branded frames also appear to be manufactured by Lightcarbon, so there is some cooperation between the two.

To be continued

I was just watching Peak torque and he he's ranting regarding toe overlap on the Yoeleo G21 (https://www.youtube.com/watch?v=4XpcQncoL_E). The frame geometry comes close to the LCG074.

Does anyone have trouble regarding toe overlap with big tires? This could make me want to change from 52 to 55 in frame size. I'm 182cm so probably 55 is the best size anyways but a bikefit will hopefully give me a good answer.

Answer is frame flex, by not making it rigid but flexible in one direction. check https://www.proxcarbon.com/prox-carbon-bike-gravel-frameset-micro-suspension-pivot-design-with-handlebar_p129.html.

So far I'm really happy with my build. No issues at all.

How good is it compared to other gravel frames? I don't know since I'm primary a road cyclist that has a hardtail MTB for the colder months.

So when looking at the comfort, I have the feeling that the rear of the bike is more comfortable than my mtb. However I don't know how much of that is due to the suspension pivot and how much to the flexing seat post.
I don't have the feeling that the system is giving me any issues that a flexy rear triangle might. Power transfer is fine as far as I can tell, no disk brake rub etc.

Post by: moo5000 on November 17, 2025, 01:57:35 AM
Thank you, your feedback from you own insight is highly appreciated. I also own a race and a hardtail MTB. Due to lower back problems i'm looking for a (relatively) more comfy ride. I'm hoping that the micro suspension does work but I'm guessing it's very minor, but all bits will help. As long as it does not have a big negative impact on driveability. Also seatpost and bigger tires/lower pressure will help for comfort. I just did a bikefit and the frame geometry will work good for me.

If there are more real world experiences from other people, I would love to know :).

Not me. When you say the bearing is loose, do you mean you feel the play when you hold the front back and put you finger on the top cap and push the frame forwards or do you mean the bearing fit in the frame is not perfect?

If I pull the front brake, I can feel and hear that the shaft of the fork moves a bit.

Until now, I haven't investigated in detail the reason behind this movement.

With a different bike, I had the same behaviour and I could eliminate the movement by tighten the ahead cap.

Did you shorten the steerer tube sufficiently? If not, it might be that the top cap gets stuck on the expander in the steerer tube and thus not apply sufficient compression.

So far I really like it. I have tested it on a few nice gravel roads, a bit of single trail, normal roads. Feels good, except for steep descents... which is not really the terrain it is build for.

Maybe I will swap the stem for a shorter one. Maybe also swap the drop bar to something with more flare.

Post by: bikepacker_dude on December 10, 2025, 12:47:19 AM
Guys- I need your advice.

Is it normal for the seat post to be loose in the seat tube insert hole?
Mine is loose and I have asked LightCarbon for their tolerances. Not sure that I got it correctly from Cassie at ProX, she says that seatpost is 27.2 and seat tube is 27.2-27.35 (looking at their drawing 27.2-27.35 seems to be the seatpost tolerance)

Measuring with a caliper (not digital) I get this:
The seatpost is 26.95 mm and the seat tube is 27.95 mm!
That seems huge. The difference in diameter between the seatpost and the seat tube is 1.0 mm (on the worst spot it’s even 1.3 mm)!
Or am I just wrong? To me this seems way outside any tolerances for a tight and good fit of the post inside the tube.
Title: Re: LightCarbon Gravel LCG074-D Micro Suspension Pivot Design
Post by: moo5000 on December 15, 2025, 09:06:23 AM
I'm no expert but seems to loose to me, according to AI,normally between 0 to 0,05mm, max 0,2mm.
Title: Re: LightCarbon Gravel LCG074-D Micro Suspension Pivot Design
Post by: renegade1848 on December 20, 2025, 01:35:31 AM
1 mm is way too much! Question is if that is only at the very top or all the way through. If the SP rocks even after clamping, you got a problem. There‘s a bunch of hacks on the web how to fix this but honestly, if this is a new frame LC should provide you a solution.
Title: Re: LightCarbon Gravel LCG074-D Micro Suspension Pivot Design
Post by: bikepacker_dude on December 27, 2025, 02:23:49 PM
It seems tighter down the tube than on top. Lightcarbon has responded and they are sending me a new seatpost with slightly larger diameter.
I have built the bike now and done two test rides, both with original seatpost and Canyon Ergon seatpost and it doesn't seem to slip.

Here are some photos of the bike

So after a few month of riding in the woods, a first report.

I really like the frame, the look is very nice and the ride quality high. Sometimes i have the feeling it is a bit too soft (mainly at high speeds) and sometimes, it could provide more damping (rough descents). So for me it is a very nice build, that I really like riding.

After a couple of rides during muddy winter conditions, I have noticed that the rear tire is rubbing against the frame (near the rear suspension). I use Schwalbe One Pro RS 50mm front and rear. So I guess the 50 mm tire is bit too much for the rear wheel.

Hey, great looking build.

If I could ask, when did you order and how long roughly did it take for the frame to make it to you? I decided to splurge on it 4 weeks ago hoping to get it before season starts but apparently they don't have any fork availability atm and the current estimated production time is another month :(

But the frame looks very good in that red color, i cheaped out and got default matte black and totally paid final price of 890$ for the version with SP03 seat post, default paint, integrated handlebars and CEMA ceramic bearing BB(it includes shipping and paypal handling charge as well). Finished my order with Tina from lightcarbon and She has been great help but still very disappointing there was estimate of 2 weeks for delivery and no mention of forks being out of stock, so for anyone aiming for this frame in this future it would be worth to make sure before ordering.

I ordered 26. Feb. Frame was ready for shipping 24. Mar and arrived in Norway 9. April
They had stock of both frame and fork at the time. But there was a queue for painting.

Small update from my end. Have ridden about 2000km on the bike so far, including the Traka 200 this past weekend. Bike performed flawlessly!

The front end (not sure whether it's the fork or head tube) is not the stiffest, but no problem for me. Wouldn't call it comfortable per se though. But it's difficult for me to compare, as this is my first gravel bike (having ridden road bikes and MTBs for many years). Rear appears to be quite comfortable.

Paint job is holding up well.
So far very happy with my purchase!

Just curious but asking anyone that has the frame already, did you try measuring what max size 1x chanring you can fit? will using the SRAM wide standard allow for more than advertised 42T? Im planning tu order a chainring soon and wondering if its possible to push a bit further than Lightcarbon claims is max possible.

Also saw a few posts on 071-Pro forum about that frame feeling pretty slow during sprints and descents so if anyone would be able to elaborate and describe their experience with 074-D it would be great.

Thanks.

I have dub wide spindle on mine and have it fit with a 42t. I wouldn’t push it any bigger as the gap to the chainstay is pretty tight.

It seems tighter down the tube than on top. Lightcarbon has responded and they are sending me a new seatpost with slightly larger diameter.
I have built the bike now and done two test rides, both with original seatpost and Canyon Ergon seatpost and it doesn't seem to slip.

Here are some photos of the bike

can you post photos of the rear tire fitment? I'm seeing conflicting reports of 50mm width tires clearing the pivot mechanism and I'm wondering if wider internal rims allow the tire profile to be lower and thus improve clearance.

Im currently using 45mm pathfinders on 32mm internal rim width, i tried taking some pics for you to the best of my ability but imo the limiting factor is the clearance on down triangle arms not the pivot mechanism. The wheels im using are elitewheels gravel aero+.

 The attached pictures are:
-clearance from pivot mechanism arm
- clearance from down tube on rear triangle(non drive side)
- Pic for visual clearance
- total tire width

Finally received my frame after around 2 months since order time. I ordered exactly on 27th of march and recieved order comfirmation the same day. I ordered size 55 with Cema ceramic bearing BB, SP03 seatpost, and 420/90mm handlebars. After around a month and a half i recieved an information that frame, fork and seatpost are ready but handlebar production would take another month so i swapped to 420/100mm and recieved the frame 1st of june, total price was around 890$ including all fees and delivery to Poland. The build was pretty straightforward and I only had problems with internal cable routing as left side cable hole had very tight tolerances and required a lot of effort, I alos plan to cut my seatpost shorter as the included one is way too long for this frame.

I used aliexpress for majority of my other parts and below is the total list of them with prices that include shipping and taxes:
-Frame: Lightcarbon LCG074D size 55 (890$)
-Seatpost: SP03 model included with frame
-Handlebars: included with frame in size 420/100
-BB: Cema brand ceramic BB purchased from lightcarbon
-Groupset: Ltwoo egr electronic groupset from 80 designer store (300$)
- Wheels: Elitewheels gravel aero+(500$)
- Disc brake rotors: VXM rotors from aliexpress(12$ each)
- Cassette: Goldix 11 speed 11-42T(25$ leftover from my trainer and used with old bike intending to finish it off before swapping to 12 speed)
- Chain: Shimano ultegra 11 speed chain(20$)
- Seat: RYET carbon seat(31$)
- Bar tape: Supacaz violet-blue color(23$)
- Tires: Specs pathfinders TLR 45mm black sidewall(47$ each)
- Cranks: Shimano grx 610 1x 40T crankset(74$)
- Pedals: Shimano M520 spd pedals(24$)
-Misc itesm: Batteries for shifter, batteries for RD, mr.ducky, chainstay guard(30$)

Total cost: around 2000$
Total weight:8,5kg(pedals and bike computer mount included)

Majority of parts were bought on various discounts and with coupons while waiting for the frame, only managed to get around 150km on this bike atm.

Overall the ride feels great, you can feel the micro suspension work especially on rougher terrains but it makes the front fork feel quite stiff in comparison. I had some problems with seatpost and handlebar screws slightly loosening but it only happened for first 2 rides and stopped afterwards. Still planning to change a few things around the bike but frame size 55 feels very good for 182cm height, I would love to see them ship with shorter seatpost but that is something i can always cut off so no real issues there.

For total weight of each component
Frame: 1250g
seatpost: 250g
handelbars: 450g
fork: 550g


I will also post few more bits of information that might help people:
All rightcarbon tourque values are for dry conditions but they do include locktite on majority of their screws from what i could tell.
45mm tire feels just right and 50mm might be very close to pushing the limits so i would recommend going 48mm max if you plan to ride in muddier conditions.
With 40T 1x chainring i seem to have around 13-14ishmm distance from the frame but im not sure how much realistically the frame flexes with micro suspension and how far it can be pushed
Downtube storage area is extremely narrow so not much will fit in there(i had troubles putting more than spare TPU tube and patchkit in the included bag, my multitool was too wide and my pump too long and made the bag too stiff to insert back)

so based on 8mm clearance for 45.5 as measured, then 53mm as measured should fit with a standard 4mm of clearance?

I don't want to state any facts as I have not tested wider tires than my current 45mm, but depending on how tire fits it might? also depends on how high the knobs are on the tire.

Based on my current setup it seems 50 will work and 53 might? but that would be pretty tight fit. Also i will mention that LCG071D when it was first introduced offered up to 53mm tire support that was later reduced to 50mm once they added T47 and UDH upgrade, and LCG074D is based on 071D but with just micro suspension. So it might work but again it is just based on some anecdotal information and few simple measurements based on my size 55 frame. Smaller sizes might also have slightly lower tolerances but i cannot verify that information without any evidence atm but i think its worth keeping in mind.

I'm under the urge to buy this frame and build it with a suspension fork.
Please discourage me  ;D

I don't think you'll be able too as this frame has a  1 1/2 inch straight steerer tube, most suspension forks are tapered as far as im aware.

But isn't that the standard thing to have the internal cable routing?
Wide bearing on top with the C ring so cables can run trough it.

Just playing around with geometry and Gemini ;D

I compared the frame with a 40mm Kocevlo fork (roughly) to my current bike, geometry ends up kind of similar but further back from the BB, shouldn't be a huge issue with a 0 offset seatpost
