Bottom bracket bearing kit Enduro Bearings Shimano BSA ABEC 3

BK-54101 – ABEC-3 bottom bracket bearing kit for Shimano 24mm x 37mm external cup BBs.

This entry-level Enduro bottom bracket bearing kit includes ABEC-3 radial bearings, seals and spacers needed for a precise, professional installation.

Enduro ABEC-3 bearings are engineered specifically for bicycle use. Their races are made from 52100 high-carbon chromium alloy, and the bearings use grade 10 Balls, LLB seals and high-pressure, waterproof grease with a 90% fill. All Enduro radial bearings are designed with deep grooves to accommodate the largest possible balls, providing maximum bearing contact area and greatly increased bearing life.

For the easiest removal and installation of this bearing kit, we recommend the BRT-003 24m x 37mm bearing tool. BRT-003 allows you to quickly remove and install bearings with a few twists of the wrist while the BB is still in the bike.
