Product description

This is a unique custom bearing 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 often made from a material that is softer than , and over time quite often the bearing seat can become slightly oversized from use. These replacement bearings have been made just slightly oversized (0.1mm) to compensate. This version features a 22mm ID extended inner race that designed specifically for SRAM GXP drive-side installation. For non-drive and Shimano cranks we also make MR24371 for the same oversized BB90 issue. The Enduro line of bearings are available in high-carbon chromium , 440C stainless , ceramic-hybrid and XD15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
