ENDURO BEARINGS Mr 22371 llb-e - abec 3 (radial) - 22x37,1x8/11,5

Upgrade your cycling performance with the MR 22371 LLB-E ABEC-3 radial bottom bracket bearing, specially designed for Trek BB90 and SRAM GXP cranksets. Featuring high-quality 52100 high-carbon chromium alloy races paired with grade 10 balls filled to 90%, this bearing offers exceptional durability and smooth rotation. Equipped with high-pressure, waterproof grease, it ensures reliable operation in all weather conditions.

This custom bearing is a perfect solution when replacing worn or oversized seats in softer materials like aluminum frames. Slightly oversized by 0.1mm, it fits precisely into the BB shell, especially for SRAM GXP drive-side installations. For non-drive side and Shimano cranksets, we recommend our MR24371 model, designed for similar oversized BB90 applications.

Our Enduro line includes bearings made from high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless steel balls. Engineered with deep groove races and dual-lip seals in micro-grooves, these bearings provide superior protection against dirt, water, and debris. Weighing only 32.8g and capable of static loads up to 834lbf / 3.71kN, they are ideal for demanding cycling conditions.
