Shimano XT BB MT800 PA Bottom Bracket

The Shimano XT BB MT800 PA Bottom Bracket steps up the 11 speed game with durable bearing seals and smaller bearings than previous models to reduce friction and provide a smooth pedal turn every time you clip in. It's compatible with 89. 5 and 93mm wide shells with a 41mm internal diameter. This bottom bracket pairs with MTB 24mm Hollowtech cranksets and will fit frames with the BB86, BB91, and BB92 bottom bracket standards.
