SILENT, INSTANT ENGAGEMENT.
Made in the USA, Onyx Racing hubs have shells made from 7075 aluminum alloy and come in a huge range of powder coat and anodized colors.
Onyx Racing uses sprag clutches in their rear bike hubs. Sprag clutches are unique because they engage instantly but operate silently. In addition, all sprag elements maintain gentle contact with the driver and hub body, gliding with minimal friction until torque is applied. Their unusual shape allows freewheeling in only one direction. When a rider pedals to induce torque, the sprags rock slightly to wedge between the hub and driver, giving Onyx hubs infinite points of engagement, always ready to go when you are. Since there are no teeth or spring-engaged pawls like those found in conventional ratchet mechanisms, Onyx hubs are almost noiseless during freewheeling.
Now stocked in Perth, Western Australia at Empire Cycles, Onyx Hubs are available to order for MTB and BMX in 24 different colours.
