Shimano Deore XT M8000 Crankset - No Chainrings. If you're looking to upgrade to 11-speed, but haven't made a choice about going 1x or 2x yet, the Shimano Deore XT M8000 crankset without chainrings might just be the right choice for you. By purchasing just the arms and spider, you can get your bike built up, and then make a choice about gearing later, choosing your own custom chainring combinations, or purchasing different combinations of chainrings that can be swapped out to suit the riding conditions. The Deore XT M8000 Hollowtech II crankset is features an all-new 11-speed design that gives you the power to choose how and where you ride. A 2x11 drivetrain will give you 22 possible gearing combinations, so there is truly no terrain that will hold you back. The new 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 chainring gearing options also keep the ratios loose, for a minimal shifting gap with no large leaps in gearing--making it easier to maintain your cadence and keep your rhythm out on the trail.
