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

Discover the exclusive Enduro Bearings XD-15 Pro Bottom Bracket, featuring high-performance ceramic-hybrid cartridge bearings pressed into precision-machined aluminum cups that thread directly into your bike's BB shell. Designed for BB386 framesets and SRAM DUB cranksets, these bearings utilize the same durable XD-15 steel as our renowned Corsa bearings, offering a 15-degree angular contact sealed bearing in a standard cartridge size.

With deep-groove raceways and large Grade 5 Silicon Nitride ceramic balls, XD-15 Pro bearings deliver increased contact area, enhanced performance, and extended longevity. Manufactured in California, USA, these bottom brackets combine corrosion-resistant, cryogenically treated nitrogen steel races with premium Silicon Nitride ceramic balls through a proprietary process, ensuring maximum durability and high performance.

Bike Radar praised the XD-15 as hands down, the best bottom bracket we have ever tested. We back our XD-15 Ceramic-Hybrid bearings with a full lifetime warranty against wear and corrosion. Unlike other bearings, XD-15 improves with use—balls and races wear in together, making the bearings smoother and faster over time, unlike other ceramic hybrids that tend to slow down.

At Enduro, we offer over 50 different bottom bracket options for various shell types and cranksets, including threaded BSA, BSA 30, Italian, and T47 systems, as well as press-fit options like our TorqTite and Delrin Cup models. We even provide flanged, double-row bearings for 30mm cranksets in BB86 shells!
