Performance & Use Case
The Trek BB90/95 Bearing Kit is the OEM replacement for the bearings in a Trek BB90 or BB95 bottom bracket shell - a frame-specific standard found across Trek's road and mountain bike range. When the original bearings wear, the BB90/95 Kit provides a direct, guaranteed-fit replacement without the need for adapter cups or third-party conversion.
Construction & Materials
Each kit ships with two of Trek's integrated steel bearings - the same units Trek specs in original frame builds. The BB90 and BB95 shells press the bearings directly into the frame, with no cups required.
Compatibility
Fits any Trek frame with a BB90 or BB95 bottom bracket shell. Two spindle-compatibility options cover Shimano Hollowtech II (24mm) and SRAM GXP (24/22mm) cranksets. Select the variant that matches your crankset. Not compatible with BB30 cranks.

About Trek
The best bike, ridden everywhere.
Founded in a Wisconsin barn in 1976, Trek has grown into one of the world's most recognised bicycle brands without losing the obsession that started it all: build the best bike, ride it further, share it with everyone.
Trek believes the bicycle is a simple solution to many of the world's most complicated problems. Every bike Trek builds — from the Madone race weapon to the Marlin trail bike — is made with that conviction. More riders, more often, on better bikes.
