Shimano Deore XT WH M8000 27.5 Mountain Wheelset. The new Deore XT M8000 27.5650b wheelset is Shimano's Race version optimized for the faster acceleration and smoother rotation prized by cross country riders in search of optimal performance. Shimano has lightened up both the rims and the hubs when compared to the previous XT wheels while the rim's offset design ensures superb strength and reliability. Both front and rear hubs are set up for thru axle systems and the 27.5 aluminum rims are UST tubeless ready. Additionally, since the new Shimano 11 speed mountain cassettes don't require a new freehub standard, the rear hub is compatible with Shimano 891011 speed drivetrains.
