The new Shimano XTR M9000 group brings shifting to the next level for mountain bikes. Where other brands choose for a single or a double, Shimano chooses to create a group for every type of rider. Single,double or triple everything is possible.
The new XTR M9000 Direct Attach I-spec is an good example. The left shifter can be converted to a two or three click system, which means this shifter can be used on a double or a triple. The shifter has been completely redesigned. A carbon shifting lever brings it weight even further down. It is possible to move the shifter vertically and horizontally to achieve the optimum ergonomics.
The Direct-Attach I-spec system is only suited for use with the new XTRM9000 magnesium brakes.
