What are the specs for the thru axles on these? And any recs for decent titanium ones?

Man the parts cannot come in soon enough. Current bike fit is proving to be too aggressive and of course I built it with integrated bars. Never again! XMCS wheels shipped Monday; Tufo Comtura Prima 32s on the way, I think all I need to finish the build are thru axles and a bottom bracket. Stoked!

Yep I think the way to go is prototype in whatever you have lying around, then order a final print in the strongest material that makes $en$e. These tiny pieces should be dirt cheap.

$300 + shipping in contiguous US. Free pickup if you are local to Charlotte, NC.

Rear wheel needs to be trued/tightened up. Comes with tools to do it (has to be adjusted in spoke holes). Shimano hub.

What do the wind tunnel tests say about these barn door frames specifically? I feel like an aero road bike can get you in the TT position with the right bars while having more tire clearance and less weight. TT frames seem mainly like an aesthetic choice these days.

With saddle height at 800mm (from center BB to saddle top) and using Selle Italia SLR that is 248mm long and has 50mm regulation on rails You can have 50-95mm saddle setback (there is 45-90mm on screenshot but seatpost has 5mm offset).

EDIT:

In my calculations, I also did not take into account the width of the saddle mount, which limits our ability to extend the saddle forward or backward. Probably more realistic setback values for a saddle at this height are 65-85mm (including a 5mm offset).

EDIT2:

According to my calculations, if the width of the saddle holder is 30mm, the possible setback presents itself as follows:

Saddle Height               Possible offset
750mm                        57-77mm
800mm                        65-85mm
850mm                        74-94mm

This photo shows the true STA (BB to saddle) is not far off from regular bikes at regular seatpost heights. These offset seatposts really obfuscate fit calculations. Im not even sure they are that progressive TBH as it really depends on their angle/offset. They look cool though

Hey!!! Thank you!!!

You should offer some kind of paid memberships.... I'd be happy to donate, love this place

This is awesome!

You should add BTLOS, they have lots of great options. I wish there was something like this for other components

Mine came in.... they weigh ~291g. Kind of bums me out when Tavelo Rise integrated bars weigh less but I need to dial my fit before committing to integrated bars again. But they seem nice and decent quality.

What is the usual response time from Light Carbon? I sent them an e-mail 10 days ago to ask about the frame and wheelset, and I still haven't gotten a response.

There was a Chinese holiday. Might be worth poking them again.

Reccomendations for shorts/bibs for a heavier rider (~85kg)?

Im curious as well. Im not worried about how its going to ride, it's an upgrade over my first 2 bikes and outside of my weight Im not a demanding rider. Will be curious to hear how it is to people who are more particular. I will prob do a Youtube video on it once it is built, seems like nobody has made anything for it.

I went with this:



Going to be a while until my build is finished but this should be interesting. Im going to run the cables outside of the bars as well.

Man, where were you like a month ago. Why selling? You just built it lol.

You had me at the Homer Car

I just bought a new frame so Im out. I do feel like the niche is just basically getting like 60-80% to TT bike geometry, but with road tube sections and 2023 gravel tire clearances. Non-proprietary front end, threaded and low BB, yadda yadda. Step one has to be consensus on parameters.
