ABEC-3, Oversized, Bottom Bracket Bearing Kit for 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 is a unique custom bearing kit that is not used a lot, but when you need it, its a major problem solver. 

Trek BB90 bottom brackets require the bearing to be directly pressed into the BB shell that is usually made from a material that is softer than steel (carbon or aluminium), and over time quite often the bearing seat can become slightly oversized from use. The custom replacement bearings in this kit have been made just slightly oversized (0.1mm) to compensate for any slop that may have developed in the BB shell. 

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 (EB9040) allows you to quickly remove and install bearings with a few twists of the wrist while the BB is still in the bike.
