Shimano XTR FH-M9111-B Center Lock Rear Hub 12x148mm
The XTR FH-M9111-B Rear Hub is Shimano’s top Boost 12x148mm standard hub for mountain bikes with the Center Lock compatibility ensuring a simple and secure mount for the disc rotor. High precision angular contact bearings give both lateral and radial support to the balls to improve durability and keep the hub running smoothly, and the wide placement of the bearings gives better rigidity when combined with the Boost spacing. Weather protection is provided by the double contact seals and internal grease sleeve.
The Micro Spline freehub is compatible with 12-speed Micro Spline cassettes and allows the use of a 10 tooth sprocket which is particularly useful on 1x drivetrains. The 10° engagement gives quick pickup and power for accelerations and lifting the front end over obstacles. An anodised finish in classy XTR grey matches the rest of their premium groupset.
