BK-54101 - ABEC-3 Bottom Bracket Bearing Kit for Shimano 24mm x 37mm External Cup BBs Upgrade your bicycle's bottom bracket with the Enduro ABEC-3 bearing kit, designed for Shimano 24mm x 37mm external cup BBs. While it offers entry-level performance, it surpasses many other products on the market by combining high-quality radial bearings with all necessary seals and spacers for a precise, professional installation. Crafted specifically for cycling, these Enduro ABEC-3 bearings feature 52100 high-carbon chromium alloy races, grade 10 balls, LLB seals, and 90% fill waterproof, high-pressure grease. Deep grooves in all Enduro radial bearings maximize contact area with large balls, ensuring extended bearing life. For effortless removal and installation, we recommend using the BRT-003 bearing tool, which allows quick and easy bearing replacement with minimal effort while the bottom bracket remains in the bike.
