With the cold-forged, trail-optimised XTR FC-M9020 you get the most advanced crank in the Shimano range. It is packed with technologies that guarantee first-class stability, lightness and power transmission. The outboard/B version of the FC-M9020 has a further outer chain line and is therefore suitable for the BOOST standard with 148 mm rear hubs.
Hollowtech II The development of the Hollowtech II crankset took place with a view to an optimal and efficient power transmission. 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.
Dyna-Sys 11 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. Several chainrings in the front mean consistently higher efficiency across the entire spectrum.
Hollowglide Hollow large chainring: The extremely rigid hollow structure reduces the weight with the same strength. This results in better power transmission and faster, more precise shifting.
Shimano XTR The new XTR M9000 series presents the most advanced XTR mountain bike components and wheels ever.
