The SHIMANO DEORE XT bottom bracket uses high quality sealed bearings and is offered in threaded and pressfit options. 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.
