Enduro Bearings Bottom Bracket | BB386 to Shimano Hollowtech II

BKC-0896 - TorqTite, Ceramic-Hybrid, XD-15, Angular Contact, Bearing Bottom Bracket for BB386 framesets and Shimano 24mm cranksets
An Enduro Bearings exclusive, our XD-15 Pro BBs feature XD-15 15° Angular Contact cartridge bearings pressed into precision machined aluminum cups that 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 15° angular contact sealed bearing in a standard-sized cartridge. XD-15 Pro bearings feature deep-groove raceways allowing maximum-sized Grade 3 Silicon Nitride ceramic balls for increased contact area and improved performance and longevity. Enduro XD-15 bottom brackets are manufactured to the highest standards at the Enduro Bearings production facility in California, USA. Enduro XD-15 bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls in a proprietary process that results in the ultimate high-performance bearing setup.

Find out why Bike Radar reported the XD-15 as "Hands down, the best bottom bracket we have ever tested." We are sure you will agree that we offer an unlimited lifetime bearing and race warranty. The most impressive feature of these bearings is that they only get better with use, unlike other approaches. As the bearings wear in, the balls make the races even smoother. So when compared to other ceramic-hybrid bearings on the market that claim speed and power advantages on day one, Enduro XD-15 bearings not only provide the same initial benefits on day one but will get even faster and smoother with time and use. In contrast, the other ceramic-hybrid options will only get slower.

The right bottom-bracket solution for the ever-growing range of bicycles on the market is not always easy. At Enduro, we currently offer over 50 bottom brackets for various bottom bracket shell and crankset combinations in multiple price/performance levels. Enduro bearings offer threaded options for BSA, BSA 30, Italian, and the robust T47 system. For press-fit bottom brackets, we created the oft-copied, thread-together Torqtite bottom brackets and press-fit Delrin Cup options. We even offer flanged, double-row bearings to fit 30mm cranksets in BB86 shells! Find your bottom-bracket solution here!
