KAPIC aluminium Cranks are compatible with Boost (L141) axles.
KAPIC’s 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 our 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
