ENDURO BEARINGS Bsa 68/73mm bottom bracket to 30mm - xd-15 pro - black

Upgrade your bike with the exclusive Enduro Bearings XD-15 Pro Bottom Bracket, designed for 68mm BSA framesets and 30mm cranksets. These high-performance ceramic-hybrid bottom brackets feature XD-15 15-degree angular contact cartridge bearings pressed into precision-machined aluminum cups that thread seamlessly into your BB shell. Crafted from the same durable XD-15 steel as our renowned Corsa bearings, these sealed bearings incorporate deep-groove raceways and Grade 5 Silicon Nitride ceramic balls for maximum contact area, enhanced performance, and extended longevity. Manufactured in California, USA, the XD-15 Pro combines corrosion-proof, cryogenically treated nitrogen steel races with advanced ceramic balls through a proprietary process, delivering unmatched durability and efficiency. This thread-in design allows easy installation of 30mm/386 cranks into BSA threaded shells without hassle. Recognized by Bike Radar as hands down, the best bottom bracket we have ever tested, we back these bearings with a lifetime warranty against wear and corrosion. Unlike other bearings that degrade over time, XD-15 ceramic-hybrid bearings improve with use—balls and races become smoother, increasing speed and performance. Whether you're upgrading or building new, find the perfect bottom bracket solution from our extensive range, including BSA, BSA 30, Italian, T47, and press-fit options, all engineered for durability and performance.
