ENDURO BEARINGS Torqtite bottom bracket - bb386 to 30mm - xd-15 pro - black

Discover the ultimate in bottom bracket performance with the Enduro XD-15 Pro, an exclusive Angular Contact bearing designed for BB386 frames and wide 30mm cranksets. Featuring XD-15 15-degree angular contact cartridge bearings pressed into precision-machined aluminum cups, these bearings thread directly into the bottom bracket shell for a secure fit. Crafted from high-quality XD-15 steel, the sealed bearings incorporate deep-groove raceways and large Grade 5 Silicon Nitride ceramic balls, ensuring maximum contact area, enhanced durability, and superior performance. Manufactured in California, USA, at Enduro Bearings' state-of-the-art facility, these bearings combine corrosion-resistant, cryogenically treated nitrogen steel races with advanced ceramic balls through a proprietary process, delivering unmatched high-performance reliability. Praised by Bike Radar as hands down, the best bottom bracket we have ever tested, the XD-15 Pro offers a full lifetime warranty against wear and corrosion. Unlike traditional bearings, these actually improve with use—balls and races become smoother over time, maintaining speed and power advantages longer than other ceramic-hybrid options that tend to slow down. With over 50 different bottom bracket types, Enduro offers solutions for various shell standards including BSA, BSA 30, Italian, T47, and press-fit options like Torqtite and Delrin Cup. Perfect for a wide range of bicycles, these bearings set the standard for durability and performance.
