Shimano Deore XT BB-MT800-P

The BB-MT800-P is designed specifically for Shimano Hollowtech II cranksets with a 24mm spindle. If you are running a different crank standard, such as SRAM DUB or a 30mm spindle, this bottom bracket will not be compatible.

This is a press-fit bottom bracket designed for frames with an 89.5mm or 92mm shell width and a 41mm shell diameter, commonly referred to as the BB92 standard. You should verify your frame's bottom bracket shell specifications before purchasing to ensure a proper fit.

No, the bearings in the BB-MT800-P are sealed and not designed to be serviced or replaced individually. When the bearings eventually wear out, the entire unit is replaced as a single component.

Because this is a press-fit bottom bracket, you will need a dedicated press-fit installation tool to safely seat the cups into your frame. Avoid using improvised methods, as they can damage the frame or the bearings.

No, this model uses high-quality steel bearings. While ceramic bearings are often marketed for marginal weight savings or reduced friction, the steel bearings in this XT-level unit are chosen for their durability and reliability in harsh mountain biking conditions.
