The BB386 - Torqtite - XD15 Pro - 30mm is a bearing bottom bracket designed for BB386 framesets and wide 30mm cranksets. This product is an exclusive from Enduro Bearings, a renowned brand. Our XD-15 Pro BBs feature XD-15 15° Angular Contact cartridge bearings that are pressed into precision machined aluminum cups. These cups can be easily threaded directly into the BB shell. The XD-15 Pro bearings utilize XD-15 steel, the same material used in our XD-15 Corsa bearings. They offer a 15º angular contact sealed bearing in a standard-sized cartridge. XD-15 Pro bearings have deep-groove raceways that allow for maximum sized Grade 3 Silicon Nitride ceramic balls. This design feature increases the contact area, resulting in improved performance and longevity. Manufactured to the highest standards at our production facility in California, USA, Enduro XD-15 bottom brackets combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls. This proprietary process ensures the ultimate high performance bearing setup. We are so confident in the quality of our bearings 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 the bearings wear-in, the balls make the races even smoother. This means that while other ceramic-hybrid bearings may claim to provide speed and power advantages from day one, our XD-15 bearings not only offer these advantages but will also continue to get faster and smoother over time. At Enduro, we understand that finding the right bottom bracket solution is not always easy. That's why we offer over 50 different types of bottom brackets, catering to various bottom bracket shell and crankset combinations. Our range includes threaded options for BSA, BSA 30, Italian, and the T47 system. We also provide press-fit options such as our thread-together Torqtite bottom brackets and press-fit Delrin Cup options. Additionally, we offer flanged, double-row bearings to fit 30mm cranksets in BB86 shells.
