The Shimano XT BB-MT800 bottom bracket is the ideal choice for MTB setups with BSA (English) threading. Thanks to Hollowtech II technology, it offers smooth pedaling, excellent power transfer, and superior durability, even in challenging conditions like mud, sand, and rain.

The aluminum cups ensure lightness and strength, while the new sealed bearing system protects against contaminants, extending the bottom bracket's lifespan. Compatible with all Shimano XT and SLX cranksets, with a specific color for the M8000/M7000 series.
