Phil's Standard bearings are an extremely high quality stainless steel cartridge bearing with a 100% Phil Waterproof Grease fill and have full contact seals to ensure maximum durability.

Phil's Carbonyte bearings are an extremely high quality stainless steel cartridge bearing with a 30% fill with proprietary Carbonyte grease and have a partial contact seal, and every internal specification has been optimized to produce a low rolling resistance.

Sold individually.

Phil's Carbonyte bearings use a proprietary grease applied to provide protection against wear while allowing for the low rolling resistance you would expect from a ceramic bearing. Bearing seals are are not full-contact, so we do not recommend these bearings off road or wet/corrosive environments.
