BK-5418 - ABEC-3 Bottom Bracket Bearing Kit for Shimano 24mm cranksets and Trek BB90/95 framesets
Enduro's entry level BB bearing kit, though many steps up when compared to other products on the market, we couple our ABEC-3 radial bearings along with all of the necessary seals and spacers to complete a precise, professional installation. This press-fit kit features an application-specific drive-side bearing with an extended inner race along with 22mm and 24mm outer seals to keep the elements out.
Engineered specifically for bicycle use, Enduro ABEC-3 bearings feature 52100 High-Carbon Chromium alloy races paired with grade 10 Balls, LLB seals and 90% fill high-pressure, water-proof grease. All Enduro radial bearings are engineered with deep grooves to accommodate the largest balls possible, 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.
