With the M8000-B, Shimano has completely renewed its outstanding XT group and, as with the XTR, relies on an 11-speed drive that scores with an incredibly wide range of applications. The crank with Rider Tuned ratios guarantees optimised bandwidth, precise gear changes and maximum drive efficiency.
Outboard This Deore single crank is especially suitable for 650B and 29 bikes. With a 3 mm outward offset chain line, the Outboard version meets the requirements for the new Boost 148 Standard.
The Hollowtech II crankset was developed for optimum and efficient power transmission. Hollowtech technology enables extremely light, hollow crank arms manufactured using Shimano's exclusive forging technology for maximum rigidity. Hollowtech technology enables extremely light, hollow crank arms manufactured using Shimano's exclusive forging technology for maximum rigidity. In addition, the Hollowtech II set has the right crank firmly connected to the axle, achieving an optimum balance between maximum rigidity and minimum weight.The real advantage of the 11-speed drive is that the entire transmission ratio bandwidth is available without having to give up the usual rhythm. Dyna-Sys 11 ensures an optimal rhythm with "Rhythm Step" courses in the most frequently used range, both on the level and on the ascent. Drive efficiency is a key performance indicator for the powertrain.
