The BKC-0801 - BSA Thread-In, Ceramic-Hybrid, XD-15, Angular Contact, Bearing Bottom Bracket is a high-quality bottom bracket designed for 68 mm BSA frames and Shimano (24 mm) cranksets. Exclusively available at Enduro Bearings, it features XD-15 15° angular contact ball bearings housed in aluminum cups that screw directly into the bottom bracket shell. The XD-15 Pro bearings utilize XD-15 steel and offer sealed 15° angular bearings with deep raceways for maximum contact area and enhanced performance. Made in California, USA, they combine corrosion-resistant steel races with Grade 3 silicon nitride ceramic balls.

The threaded solution allows for easy installation of 24 mm Shimano cranksets into the BSA threaded bottom bracket shell. The XD-15 has been named the best bottom bracket by Bike Radar and comes with a lifetime warranty against wear and corrosion. The Ceramic-Hybrid bearings actually improve with use, unlike other options that tend to slow down over time.

The range also includes press-fit bottom brackets and flanged, double-row bearings for 30 mm cranksets in BB86 shells.
