The 38mm profile rim has excellent performances in climbing and acceleration with the advanced aerodynamics, it offers a light, ridged, razor sharp and responsive ride. It is designed for cyclocross bike and road bike, it is the best choice for cyclocross riders. High TG 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.
