Below is the advantage of these new wide rims.


*Widest, tallest profile and strongest: 38mm width and 32mm depth strongly improves traction, braking control and flat protection. It also provides super tire stability even with large tire at low pressure.


*Beadless & tubeless: hookless rim wall is more smooth and straight, the tire will touch rim walls fully and mounted perfectly, allowing to run lower tire pressure without risk of air loss or pinch flats.
hookless carbon rim walls is not only provides better tubeless seal, also it is more durable and far stronger than original hook design.


*Bead lock & less tubeless burping: the small ridges on each side of the drop channel.
Some riders concern the transition to hookless bead rims will cause tyres blowing off or an increased likelihood of burping air from tubeless tyres. So we add bead lock ridges to make them with any fear and ride confidently.


*Manufactured by new manufacturing process with one-piece-layer, to make carbon fiber layer continuous and rims strongest. We have the big layer-cutting machine to cut one-piece layer, for other factories, their cutting machine is not big enough .Read more about: Technology Improve Of Light-Bicycle Carbon Rims


*Terrain: downhill / freeride / Enduro / all mountain

Hello What is the pre-order special holidays price for two rims ? If one want a print on the rims - do you actually print it or use decals ? Thanks


Light-Bicycle 2014/12/17

Hello Eran, Thanks for your inquiry. Both of the hookless 38mm wide 650B & 29er rims are ready now. We have manufactured the rims and shipped out to our customers several day. The current price is already cheap, so we only can give a discount if it is more than 10pcs rims. And the discount is not much. It is USD5 cheaper for each rim. Wish you can understand. RM650BC13 (38mm wide 650B rim) hookless: 440 /-15g, USD180/pcs RM29C14 (38mm wide 29er rim) hookless: 450 /-15g, USD185/pcs Please find attached rims cross-section drawings. For rim weave, do you prefer 3k, 12k or UD? Matte or glossy? 32H? Normally, we do the decals on rims. Please find attached light-bicycle decals for reference. Is that ok for you? If yes, you can email us the graphic you like, then we can design it on rims for your check. It is normally USD60 for one-color and two-color graphic. Thanks, Light-bicycle
