BB-set Shimano XT BB-MT800-PA Press-Fit

DEORE XT cranks turn on an updated HOLLOWTECH II press fit (BB-MT800-PA) bottom bracket. Using smaller, lighter bearings and a seal system proven on both XTR and road groups, MT800 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.Weight: approx. 68 gBSA/ITA: PressfitBottom bracket spindle profile: Hollowtech IICase width: 89.5/92 mmCase diameter: 41 mm
