Speeder Cycling SC-R55D

[Tines]

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

Yeah I have the 48D in glossy Raw. Looks great. Thanks

I built my SC-R55D last week.  In this configuration it comes in 7.05kg.  I could easily shave more grams off, but I am happy with the weight for now.  This morning was my first work out and the bike felt good under me.

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.

Do you have more pics? Considering this one as an alternative to LCR017...

[Hendie]

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.

The bike looks quite good and with potential.
The spacers however don't seem to fit perfectly, but maybe it's the picture. looks like the bottom one is too long and is not the shape of the fork. Is that the pic or a feature?

[Hendie]

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.

OK. That justifies it. In any case, nice looking bike
Keep sharing your rides

I’m interested to hear how it performs over a few hundred miles. Frame looks great to me. Just wish there was custom painting

I just saw this photo on Adapt's website.

It is the same photo that speeder uses on their website for the SC-R55D.

Are Speeder cycling and Adapt working togehter or do adapt only design frames? (sorry for beeing a newbie)
