- Supplier Warehouse In StockUsually dispatched within 3-5 business days
ABEC-3 Radial Bottom Bracket Bearing constructed with 52100 High-Carbon chromium alloy races combined with precision grade 10 Balls at 90% fill capacity. Features high-pressure, water-proof grease formulation for optimal performance in demanding riding conditions.
This is a unique custom bearing that is not used a lot, but when you need it, its a major problem solver.
Engineered specifically for Trek BB90 systems where bearings press directly into potentially softer BB shells that may expand with use. These precision replacement bearings feature a deliberate 0.1mm oversize design to compensate for seat enlargement. With a 24mm internal diameter, they're compatible with Shimano 24mm cranksets and SRAM GXP non-drive-side installations. For SRAM GXP drive-side applications, consider our complementary MR22371 bearing designed for the same BB90 dimensional challenges.
