The Onyx "Ultra SS" BMX Race Clutch Bearing is the original clutch bearing for the silent direct engagement of Onyx Ultra SS rear hubs. It is a type 442-Z needle clutch with 33 needles and is sold individually.
It fits Ultra SS rear hubs with 10mm, 15mm and 20mm axle, each also in the ISO version with disc mount. Onyx lists the bearing as part number 104761 for the Ultra SS Retrofit and New Clutch versions; the Onyx parts list shows which sleeve and driver belong to your hub. The old Ultra SS version uses a different clutch bearing (Onyx part 84397).
Onyx hubs need regular maintenance to keep working properly. A bike shop can help you with the replacement.
