Premium XT bottom bracket keeps the elements out and your cranks spinning freely.

The XT BB-MT800 uses smaller ball bearings for smooth operation while durable seals keep the dirt and grime out. The BB-MT800 is compatible with Shimano Hollowtech II cranks and 68/73mm BB shells.

Installation:

The smaller diameter 16 notch 41mm cups on this BB require the Cleanskin 4-in-1 BB Tool, or the Park BBT-59.2 41mm OD External BB Tool for installation.

If you already own a larger 16 notch 44mm BB tool you can save a few dollars with the Shimano TL-FC25 Bottom Bracket Adaptor Tool (see links & more info section).

Features:

  • Excellent seals prevent wear
  • 16 notch 41mm cups
  • Includes BB, spacers, inner sleeve and o-rings
  • Compatible with 68 and 73mm BB shells
  • For use with Shimano Hollowtech II cranksets with 24mm spindle.
