Introducing the PF30A - TorqTite - XD15 Pro - 24mm bottom bracket from Enduro Bearings. This Ceramic-Hybrid, XD-15, Angular Contact bearing is specifically designed for PF30A framesets and 24mm cranksets. The XD-15 Pro BBs by Enduro Bearings feature XD-15 15° Angular Contact cartridge bearings which are pressed into precision machined aluminium cups. These cups then thread directly into the BB shell. Made from high-quality XD-15 steel, the same as our XD-15 Corsa bearing, the XD-15 Pro bearings provide a 15° angular contact sealed bearing in a standard-sized cartridge. Our XD-15 Pro bearings have deep-groove raceways which allow for maximum-sized Grade 3 Silicon Nitride ceramic balls. This design increases the contact area for improved performance and longevity. Enduro XD-15 bottom brackets are expertly manufactured to the highest standards at our production facility in California, USA. Our Enduro XD-15 bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls using our proprietary process. This results in the ultimate high-performance bearing setup. We are so confident in the quality of our products that we offer an unlimited lifetime bearing and race warranty. Unlike other bearings on the market, our XD-15 bearings actually get better with use. As they wear-in, the balls make the races even smoother. This means that our XD-15 bearings not only provide the same initial advantages as other ceramic-hybrid bearings, but they will also continue getting faster and smoother over time and use. Finding the right bottom bracket solution for your bike is not always easy. At Enduro, we offer over 50 different types of bottom brackets to fit various bottom bracket shell and crankset combinations. We have options for threaded frames such as BSA, BSA 30, Italian, and the T47 system.
