BKC0819 | Ceramic XD-15 Angular Contact Bearing
An Enduro Bearings exclusive, our XD-15 Pro BBs feature XD-15 15degree Angular Contact cartridge bearings pressed into precision machined aluminum cups that simply thread directly into the BB shell. Utilizing the same XD-15 steel as our XD-15 Corsa bearing, Enduro XD-15 Pro bearings offer a 15degree angular contact sealed bearing in a standard sized cartridge. These bearings feature deep-groove raceways to improve longevity and to allow for maximum sized grade 5 Silicon Nitride ceramic balls. Enduro XD-15 bottom brackets are manufactured to the highest standards at the Enduro Bearings production facility in California, USA. All XD-15 bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride grade 5 ceramic balls in a proprietary process that results in the ultimate high performance bearing setup.
