BB-set Shimano XT BB-MT800

DEORE XT cranks turn on an updated HOLLOWTECH II bottom bracket. Using smaller, lighter bearings and a seal system proven on both XTR and road groups, the new bottom bracket reduces weight and bearing drag while improving mud durability. In short, less weight and increased rotational efficiency results in a faster DEORE XT ride.
