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.

Gotta love an affordable replacement cost on a wear item.

This will let you pedal your Shimano cranks all day long! No creaks and easy to install

Shimano XT BB-MT800

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.
