" Top level groupset: the shimano xtr 11-speed crank fc-m9020mountain biking has rapidly evolved since the previous introduction of shimano's top level xtr groupset in 2010; Shimano sees different directions in mountain biking with wheel sizes and riding styles changing and now defines four main categories within mountain biking; Competitive cross country is driven by physical efforts while enduro focuses on more technical challenges but both have equivalents at the non-competitive trail level; To serve mountain bikers who will only settle for the best, shimano today introduces the new rider tuned xtr m9000 groupset;
Shimano's rider tuned concept starts with the gear combinations and xtr m9000 has options for all riding styles and mountain bikes; The 1x11 drivetrain is the best option if you are a competitive cross country or enduro racer and you know exactly your skills and the level of terrain you are going to face; If you want to be competitive and flexible then 2x11 is the non-compromise choice; For those who prefer an all-round bike to explore trails and conquer every climb, shimano has developed a versatile and proven 3x11 drivetrain;
Besides the gear combinations there are two different crank arm options available; The first option is the fc-m9000 race specific crank arm with a q-factor of just 158 mm and a 3d hollow bonded lightweight left crank arm which can be used for single or double use; The other option is the fc-m9020, a trail specific crank arm with a cold forged super strong construction and a standard 168 mm q-factor for 1x, 2x or 3x setups; Both cranks have one pcd so if you want to change from a single ring to double or triple you only have to change the chainrings;
The dedicated xtr 1x chainring features retention technology with a unique tooth profile that eliminates the need for chain retention devices; New xtr m9000 provides range and ensures rhythm for diverse riding styles and terrain to create smooth, harmonic pedalling; the ultimate goa.
