MR 22371 LLB-E - ABEC-3, Extended Race, Radial Bottom Bracket Bearing for Trek BB90 and SRAM GXP cranksets - 22mm x 37.1mm x 8/11.5mm -
ABEC-3 Radial Bottom Bracket Bearing featuring 52100 High-Carbon chromium alloy races paired with grade 10 Balls with 90% fill, high-pressure, water-proof grease.
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 steel, 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 steel, 440C stainless steel, ceramic-hybrid and XD-15 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.
