ENDURO BEARINGS Bb kit bb90/95 shimano hollowtech ii - ceramic hybrid

Upgrade your Trek Madone with this high-performance Ceramic-Hybrid Radial Bottom Bracket Bearing kit. Featuring 52100 high-carbon chromium alloy races combined with Grade 5 Silicon-Nitride ceramic balls and 90% fill waterproof, high-pressure grease, this kit ensures maximum durability and smooth operation. The Si3N4 ceramic balls significantly reduce bearing wear and extend bearing life by eliminating steel-on-steel contact. This comprehensive kit includes all bearings, seals, and spacers necessary for installing Shimano 24mm or SRAM GXP cranksets into your Trek Madone.

Designed specifically for cycling, these Enduro ABEC-3 bearings feature 52100 high-carbon chromium alloy races, Grade 10 balls, LLB seals, and waterproof, high-pressure grease at 90% fill. Deep grooves allow for larger balls, maximizing contact area and greatly enhancing bearing lifespan. For easy removal and installation, we recommend the BRT-003 24mm x 37mm bearing tool, which simplifies maintenance by enabling quick bearing replacement with minimal effort while the bottom bracket remains in the bike.
