From the company that invented the freehub design comes the latest iteration and most durable version to date. Shimano's XT M785 hub features a robust freehub body that will perform under the most extreme conditions and environments. Angular contact bearings are protected from the elements via labyrinth seals. The hub body is black anodized for good looks and added durability. 135mm skewer is included. The rear freehub accepts 8, 9 and 10 speed Shimano and SRAM cassettes. The splined non-drive carrier accepts Shimano Centerlock discs only.
