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. Max spoke tension: front: 100kgf rear:140kgf.
