A smooth ride.

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.

Shimano XT BB-MT800

  • Familiarity: I've put it through the wringer

Shockingly spin-able. The amount of grease included pre-installed on the spindle interface is excessive but a super cool color.

It spins!

It's great that Shimano offers any size you need to fit your PressFit frame. They last a good while and are easily affordable!

Works Great

If you are looking for a reasonably priced bottom bracket to pair up with your Shimano crank this is it. Long lasting bearings and super easy to install.
