Shimano XT BB-MT800 Press Fit Bottom Bracket

The Shimano XT BB-MT800 Press Fit Bottom Bracket is built to keep your XT M8000 crankset spinning cleanly through the kind of conditions that mountain biking regularly throws at it. Smaller ball bearings — relative to higher-tier Shimano bottom brackets — are designed to reduce rotational drag, giving you a smoother pedal stroke without the added weight of a more complex bearing system.

Sealing is where this bottom bracket earns its place on a trail bike. It's engineered to resist dirt and water ingress, which means less maintenance interruption and more consistent bearing performance over time. It fits press fit shells from 89.5–93mm, covering the standard range for modern mountain bike frames.
