Shimano Deore XT WH M8020 27.5 Mountain Wheelset. The new Deore XT M8020 27.5650b wheelset is Shimano's Trail version whose wider, 27.9mm rim width is optimized for strength, rigidity, and superb traction sought out by enduroall trail riders in search of the ultimate in 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.
