Experience unparalleled performance and longevity with the Enduro Bearings BSA - Bearing Kit - XD15 Ceramic. Designed specifically for Shimano 24mm x 37mm external cup bottom brackets, this top-tier bearing kit combines precision engineering with cutting-edge materials to elevate your bike’s drivetrain efficiency. The unique XD-15 Ceramic-Hybrid bearings feature corrosion-proof, cryogenically treated nitrogen steel races paired with Grade 3 Silicon Nitride ceramic balls, creating a bearing system built to outperform and outlast traditional options.
Unlike standard bearings, the deep-groove design raceways in the XD-15 allow for larger ceramic balls, increasing contact area and enhancing smoothness and durability. The kit includes all necessary seals and spacers for a professional-grade installation that ensures your bottom bracket operates with minimal friction and maximum reliability. Enduro also utilizes 90% fill Kluber NBU52 grease, a specialized lubricant engineered to resist washout and improve with use, meaning your bearings will run smoother and faster the longer you ride.
Backed by an unlimited lifetime bearing and race warranty, this kit assures exceptional quality and long-term support. For easy maintenance, pairing this kit with the BRT-003 (eb9040) bearing tool allows quick bearing removal and installation while the bottom bracket remains mounted on the bike, making upkeep straightforward and efficient.
Is this bearing kit compatible with all Shimano bottom brackets?
It is compatible specifically with Shimano 24mm x 37mm external cup bottom brackets using a BSA shell fitment. Please confirm your bottom bracket specifications before purchase.
What makes the XD-15 Ceramic-Hybrid bearings different from standard ceramic bearings?
The XD-15 bearings combine cryogenically treated nitrogen steel races with Grade 3 Silicon Nitride ceramic balls, providing enhanced corrosion resistance, durability, and a unique wear-in process that improves smoothness and speed over time.
