Shimano Deore XT M8000 Bottom Bracket - 68mm and 73mm
The Shimano Deore XT M8000 bottom bracket has been updated with a new bearing and seal design. The new design features smaller ball bearings for less friction and better rotation, resulting in more efficiency. Improved seals keep mud and dirt out for a longer wear life, and longer intervals between servicing.
