The BSA - Bearing Kit - ABEC3 - 24mm from Enduro Bearings is an ideal choice for Shimano 24mm External Cup BBs. This ABEC-3 bottom bracket bearing kit provides a precise and professional installation, surpassing other products in the market.

With Enduro's custom application-specific drive-side bearing featuring an extended inner race and 22mm and 24mm outer seals, this kit effectively keeps out the elements. Its engineered design for bicycle use includes 52100 High-Carbon Chromium alloy races, grade 10 balls, LLB seals, and a high-pressure, waterproof grease that is 90% fill. These features ensure maximum bearing contact area and greatly increased bearing life.

For easy removal and installation, we recommend using the BRT-003 (EB9040) 24m x 37mm bearing tool alongside this kit. The BRT-003 allows for quick bearing adjustments while the BB is still on the bike.

The BSA shell fitment is perfect for this kit, and the ABEC3 bearings and LLB seal make it a reliable choice. The kit also includes a 1-year warranty against manufacturing defects. The Enduro reference number for this product is BKS-54101.
