A significant enhancement for the Deore XT M8000 is the introduction of a 1x11 specific 11-42T cassette, broadening Shimano's 1x11 gear range beyond the XTR's 11-40T. This feature, combined with the Rhythm Step progression, ensures a smooth and calculated transition between gears, allowing you to maintain momentum and conserve energy while riding. Additionally, the premium 11-speed chain features an HG-X11 asymmetric plate design and SIL-TEC surface treatment, further enhancing the overall performance of the Deore XT M8000. This results in superior mountain biking capabilities and a more enjoyable ride.
