451/20er 23mm width U shape 50mm depth carbon rims are our new design thanks to a slight widening of the rim, they are much stiffer. With a slightly angled brake track, they have better braking. And they are lightweight, fast, when hit a few windy sections, it could not fell a thing in the cross winds.
* Finish not only have supply normal matt/glossy,but also have supply paintless matt/paintless glossy (Newest upgraded production tech supply),paintless looks clear a bit than normal matt/glossy,near to the original suface,better appearance,and more environmental protection.
* High TG 240 degrees and high heat-resistant basalt braking surface improve heat dissipation, effectively reduce the impact in heat caused by braking to provide you with reliability and stopping power.
* Filled with 3D weave, that will make the rim stable, safe and durable.
* Manufactured by new technology, the rims’ manufacturing process are without EPS bubbles, this means the rims are molded with a air bag that has the inner shape of the rim. Unlike the traditional technology, we don’t need to cut a lid to take out the bubbles. So the rim is complete, stronger and stiffer.
* 250Gpa modulus carbon fiber reinforcement strip gives additional stiffness on spoke holes.
* Can be offered V brake/Disc brake system.
