Technology

QARBON

3K woven, high-modulus carbon fiber is bonded to the outside of a Q ring to reinforce the Q ring´s structure. Carbon fiber´s properties allow for weight reduction in comparison with conventional aluminum cranks. At the same time, the stiffer carbon fiber sheet offers increased lateral stiffness.
