The Onyx "Ultra" BMX Race Clutch Bearing is the original clutch bearing for the direct engagement of Onyx Ultra rear hubs. It is a type 437-Z clutch and is sold individually.
It fits Onyx Ultra 10mm, Ultra ISO 10mm, Ultra 15mm and Ultra ISO 15mm rear hubs. Onyx lists the bearing as part number 104760 for the Ultra Retrofit and New Clutch versions; the Onyx parts list shows which sleeve and driver belong to your hub.
