Shimano Deore XT FC M8000 34x24T 11 Speed Crankset. Shimano's renowned Deore XT groupset has made the jump to 11 speed and as a result inherits some remarkable trickle down technology from the flagship XTR M9000 component line. The Deore XT M8000's crankset design utilizes Shimano's new 4 arm crank design found in both their road groupsets and the pro level XTR 9000 cranks which maximizes rigidity for smoother shifts and more efficient power transfer. The 34x24T chainring combination in conjunction with the 11 speed 11 40T M8000 cassette also keeps the gear ratios close, for a minimal shifting gap with no large leaps in gearing. As a result you're better able to maintain a steady cadence and retain your riding rhythm out on the trails, all the while able to ride an incredibly wide range of terrain with the 22 gears on hand. The XT M8000 crankset feature new 3D composite teeth that are optimized for each chainrings specific torque load while pedaling, making them more durable and stronger, while still being thinner and lighter than previous versions. Additionally, this crankset retains Shimano's Hollowtech II integrated bottom bracket spindle to optimize the balance between light weight and stiffness.
