Shimano BB-MT800 Bottom Bracket XT Press-Fit 89.5/92mm
XT sealing for press-fit frames
A press-fit bottom bracket lives a hard life — water runs straight down the seat tube onto it. The MT800 is the XT-grade unit, with better seals and better bearings than the OE part most bikes leave the factory with.
Best for: BB92 press-fit mountain frames running Hollowtech II cranks.
