I just got my Light-Bicycle carbon 650b rims in the mail and they look great. Here are the details, as I saw them.

The price is very competitive. I think I was into about CAD $345 delivered.

The timeline to get them in hand was a little long - since I ordered immediately before Chinese New Year there was a bit of a delay, and because the 650b product is a new thing for them there was a bit of a delay. Delay + delay + shipping from the Far East = 5 weeks.

Rim Bed:

Job

In hand, these things look and feel great. The finish is consistent, dimensions (i.e. 30mm outside width) are exactly as specified on the LB website, and I didn't get any surprises building them. I suspect these are the second revision of rim from the people at LB - apparently the first revision had some quality control issues.

Unidirectional Matte Carbon Finish:

Job

Weight was as claimed (I had 366g and 372g).

With Chris King hubs (15mm and 135mm) and DT Swiss Champion spokes on brass nipples, I have a complete front wheel weight of 815g and a rear weight of 940g (bare, Stans Yellow tape included, no valve stems).

Mounting tires tubeless was easy, as you can see in the picture of the rim bed there's a nice shape to help locate the bead, and I don't think I went over 35 psi with a hand pump to get the tires to seat.

Complete Wheel:

Job

All in all, I am so far happy with the purchase and will update once I have some miles in. Does anyone else have any Light-Bicycle rim feedback? I know there's a big thread on MTBR about them, but I don't do MTBR.

Man, those look good. I may have to give them a whirl. Do you remember the ERD off them? I can go to site but lazy American.

565mm ERD for these 650b ones. The build was super easy-peasy to get them round and straight, and getting a consistent tension was also a walk in the rim job park.

I think carbon rims are easy to build because they're so stiff.

MMMM. The ERD on my flow ex's is 562. Wonder if I could make that work with the same spokes. Should be close. May have to check these out. And then order some ENVE stickers.............

Light Bicycle can do custom decals, I'd go with a play on words like ENRE.

Looked closeup at your rim shot (hehehe) and the Novatec from the front page and if you zoom in man they look really similar.

I suspect they may in fact be the same.

I never minded days like that, it was quiet (so you catch up on your reading) but productive (so you don't go out of business).

They say Toray, which is basically Guatemalan carbon.

Kidding, I think it's Japanese if we can trust that it's really Toray. I can't imagine there being that many carbon manufacturing plants in the world.
