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.

The Ultra Seal is a non-contact, frictionless seal that is placed beneath a metal shield so they are still considered maintenance free and lubed for the life of the bearing. 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.
