Shimano, Bottom Bracket, Bb-Mt800-Pa, Press Fit Type For Mtb, Right & Left Adapter

Part of the Deore XT lineup, the BB-MT800-PA is a press-fit bottom bracket built for 89.5/92mm shell widths and matched to Shimano's 24mm-spindle MTB cranksets. It uses sealed cartridge bearings mounted on a widely-spaced bearing layout derived from Hollowtech II engineering, which helps keep the crank axle steady and transfer pedaling power efficiently. The kit includes both right and left adapters for proper fitment into press-fit frame shells.
