Shimano XTR BB94 Bottom Bracket

Simple, reliable, and smooth, Shimano's XTR BB94 Bottom Bracket presses easily into your frame to give you long lasting and nearly friction free pedaling. The stainless steel bearings, composite body, and composite cups are designed to work with Shimano HollowTech II cranks, and the threadless nature of the bracket makes installation a breeze. A small plastic O ring keeps dirt, water, and debris sealed out, too, so you can put away the miles without worrying about conditions.
