Bike Hubs For Racers

Onyx racing hubs liberate your bike wheels and transform your ride.

Onyx hubs transfer power from your pedals to your rear bike wheel instantly for faster acceleration and more control. Hybrid ceramic bearings reduce front and rear wheel rolling resistance to the point of disbelief. The patented sprag clutch design removes the play and clickety–clack of pawls against teeth in the rear hub to silence your coasting.
