Manufacturer/Model By Series

Ceramic Lightning Yellow Seal Bicycle Bearing Kits are specially designed for Off Road and excessively dirty riding environments. These bearings are maintenance free and lubed for the life of the bearing. The heavy duty rubber seal provides extra protection against the harshest elements. These bearings have ceramic balls, with stainless steel races and a C3 fit. Ceramic hybrids are lighter, capable of achieving higher RPM’s and sustaining higher operating temperatures than traditional bearings. Bearings that are packed in grease will require a short break in period to loosen up.

Full Ceramic Peekaboo5 bike bearing kits are specially designed for competitive on-road or off-road riders looking for the absolute least amount of rolling resistance. Peekaboo5 bearings have high precision, grade 5, silicon nitride ceramic balls, Zirconia ceramic ABEC 5 races, a high speed Peek retainer, no friction peek seals and Boca's exclusive low friction grease. Full ceramic bearings are virtually frictionless and roughly half the weight of a steel bearing.

The Boca Bearings Ceramic C-HIP Bicycle bearing series allows you to ride further and faster, and last longer thanks to the hardened steel races and superior dense ceramic balls.
