Shimano XT FC-M8000-B1 Boost 170mm Crank Arm

The 1-speed crank is Shimano's driving efficiency MTB gear range ever and with one ring up front, rhythm is optimized. B-Version with 3 mm outboard chain line.

Following mountain biking's evolutionary path, Shimano DEORE XT M8000 delivers the 11-speed features and premium performance found on the top-of-the-range XTR-level components, elevating the performance of enduro and cross country riders on demanding trails or race circuits.

Now 11-speed, new DEORE XT M8000 brings powerful, dynamic performance that establishes a new benchmark for mountain bike excellence. With DYNA-SYS11 Shimano encourages modern mountain bikers to ride anywhere with its advanced gearing concept that helps maintain rider efficiency. Designed with both XC and aggressive trail riders in mind, DYNA-SYS11 brings enduring performance thanks to smart materials and enhanced drivetrain stability due to new derailleur and chainring designs.

Like its XTR sibling, DEORE XT M8000 offers 1x11, 2x11, and 3x11 crank options to satisfy any type of rider ability level or terrain. New 2x11 and 3x11 M8000 drivetrains, expand range while maintaining even better rhythm when paired with an 11-40T cassette for optimized cadence control. An exciting addition for DEORE XT M8000 is a 1x11 specific 11-42T cassette that expands Shimano’s 1x11 gear range slightly over the race inspired 11-40T of XTR.

Reduced capacity for dropped chains - The 1x11 tooth profile on the XTR and new DEORE XT chainsets combine wide steel teeth shape with special hooked teeth design for lasting chain retention especially over uneven terrain. These improvements increase chain retention force by 150%, increasing chain life and drastically reducing the possibility of a dropped chain.

Dyna-Sys11
The real advantage of 11-speed is the ability to have all the range you require without sacrificing the rhythm you need.
