Manufacturer/Model By Series

Our Stainless Rubber Seal line of bike bearings are specially designed for Off Road or excessively dirty riding environments. These bearings are maintenance free and lubed for life and an affordable way to replace stock bearings. The heavy duty rubber seal provides extra protection against the harshest elements. All sealed bearings are packed in grease and will require short break in period to loosen up.

Our Ultra Seal line of ceramic hybrid bicycle bearings are specially designed for On Road and relatively clean riding environments. These bearings are maintenance free and lubed for life. The non-contact seal eliminates any drag typically associated with a rubber sealed bearings and still provides extra protection against external elements. All sealed bearings are packed in grease and will require a short break in period to loosen up.

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 life. 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.

Silicon Nitride (Si3N4) Ceramic Balls are suitable for applications where high loads, high speeds and extreme temeratures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Silicon Nitirde is non-porous, non-magentic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually frictionless. and capable of spinning faster than steel balls.

Peekaboo5, Ceramic hybrid bicycle bearing kits are specially designed for use with motorcycles, road/mountain bicycles and other demanding applications. Peekaboo5 bearings have high precision, grade 5, silicon nitride ceramic balls, extra hard chrome steel races, Boca's exclusive Ultra dry Lube (UDL) coating, ABEC 5 tolerance races, a high speed Peek retainer, low friction rubber seals and Boca's exclusive low friction grease. Ceramic hybrids are lighter, have less rolling resistance and can sustain 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.
