Rotor Crank Spindle for KAPIC

Rotor's new KAPIC axle features a cleverly designed spline interface when mounted to Direct Mount chainrings that delivers a robust yet smooth engagement allowing you to maximise the efficiency in transmission of power in your pedal rotation.

Combined with their new modular KAPIC cranks and Q RINGS oval chainrings or Round chainrings, the innovative axle includes refined OCP Mount technology so you can now adjust your optimal chainring position by precise one degree increments.
