Shimano XTR M980 Hollowtech 2 Bottom Bracket
XTR has been designed to give XC racers an edge by creating the lightest, strongest fastest components on earth. XTR is the benchmark of off-road cross-country component design.
Shimano XTR M980 Outboard Bottom Bracket is E-type compatible and features cartridge bearings. The Hollowtech II design reduces the number of parts, significantly cuts down weight and increases rigidity. It also allows the bottom bracket bearings to be spaced further apart. This dramatically changes the load on the bearings to increase rigidity and bearing service life.
