Hi all,

Just wondering if anyone has tried the carbon rims from Light Bicycle http://www.light-bicycle.com/700C-carbon-road-clincher-U-shaped-45mm-rim-tubeless-ready.html#.Up1JINIW2So. Looking at building these as my first carbon wheelset. I'm around 82Kg and would use these for crits and general riding on flat to undulating terrain. Thinking of front 20 h radial and rear 24 2x DS/NDS with double butted spokes most likely DT comps or even Phil Wood as can get them cut locally. These would be laced to novatec hubs.

I currently ride kinlin xr270 front 24 2x and rear 28 2x and happy how these turned out, wondering if the carbon set will be the same stiffness or stiffer.

Did you even look a few threads down and read the open mold wide aero thread?

I recently ordered some and have some weights of the u45mm rim for everyone...

The 18h rim weighed in at 418g;
and the 24h rim at 469g.

The weights obviously surprised me as both are outside the tolerance of 450g +/- 15g specified on the webpage.

My rims cracked along the braking surface on the second ride out. i was descending a short hill, using cork pads, and weigh 70kg. I bought 24mm clinchers from Light-bicycle.

Yeah, these are covered elsewhere, but I have a set of these built as road disc wheels (28/28 2x). They have been great for ~1000 miles now. I think they are a little more susceptible to crosswinds than a set of Farsports U-shaped 50mm rims I had before, but on the whole very happy with these. The finish quality seems very good (compared to Farsports, anyway).

wow thats a real concern. i'm about to build up a wheelset with those exact rims and they 'look' ok. i'm going to use the new reynolds power blue pads for 2014.

how did LB handle the warranty? they should theoretically send you a new one without needing to send that back. its useless now.

"This was on its second outing, careful braking the rim has given way, presumably due to braking heat, I was cycling slowly down a 300ft hill in Devon."

We're you dragging the rear brake?
