Shimano XT FC-M8000-2 Hollowtech II Crankset

The XT crankset FC-M8000-2 by Shimano - rider tuned and highly efficient

The Shimano XT FC-M8000-2 crankset with 24-34, 26-36 or 28-38 tooth gradation is characterised by special drivetrain efficiency and competition-ready performance. It is one of three crank options in the XT 11-speed shifting system, which provides the right set-up for every type of rider and terrain according to the " Rider Tuned" principle. The FC-M8000-2 aluminium crank impresses with precise shifting as well as robustness and low weight. It is optimally tuned in terms of gear range and even pedalling rhythm (Dyna-Sys11 technology). The Hollowtech II design with fixed 24 mm axle, which has been tried and tested for many years, also ensures stability.

Technology:

Dyna-Sys11
Dyna-Sys11 is the name of the 11-speed shifting system for MTBs from Shimano. The focus lies on maintaining the pedalling rhythm both on flat ground and on uphill segments. The gear ratios are selected so that you make efficient progress in the most frequently used gear range and do not have to shift gears as much (" Rhythm Step" ).

Hollowtech II
Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.
