Design characters: Ø Lightweight: This MTB rim is our lightest 27.5er rim, it is wide and strong, it has excellent performance in climbing, handling and traction. Ø Filled with 3D weave, that will make the rim stable, safe and durable. Ø 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. Ø 250Gpa modulus carbon fiber reinforcement strip gives additional stiffness on spoke holes.
