ENDURO BEARINGS Torqtite bottom bracket - pf30 to 30mm (narrow) - xd-15 pro - black

Upgrade your bike with the Enduro Bearings XD-15 Pro ceramic-hybrid bottom bracket, designed for PF30 framesets and 30mm cranksets (standard spindle length less than 90mm). This exclusive enduro bearing features XD-15 15-degree angular contact cartridge bearings pressed into precision-machined aluminum cups that thread directly into the bottom bracket shell. Crafted from high-grade steel similar to our XD-15 Corsa bearings, these sealed bearings use deep-groove raceways and large Silicon Nitride Grade 5 ceramic balls for enhanced contact area, performance, and durability. Manufactured in California, USA, the XD-15 Pro combines corrosion-resistant, cryogenically treated nitrogen steel races with advanced ceramic balls through a proprietary process, delivering unmatched high-performance cycling experience. Recognized by Bike Radar as hands down, the best bottom bracket we've tested, these bearings come with a lifetime warranty against wear and corrosion. Unlike other bearings, XD-15 Pro improves with use—balls and races become smoother over time, providing sustained speed and efficiency. With over 50 types of bottom brackets available, Enduro offers threaded options for BSA, BSA 30, Italian, and T47 systems, as well as press-fit solutions like TorqTite and Delrin Cup models, plus flanged, double-row bearings for 30mm cranksets in BB86 shells.
