Shimano’s Firebolt customizable shift button placement is determined entirely by human ergonomics. This means that the shifters are now exactly where your thumbs naturally rest. Shifts can happen more quickly, allowing you to adjust to the terrain and your desired effort like never before, taking Shimano’s Rider Tuned concept to an entirely new level.
Improved efficiency: The XTR M9050 derailleurs communicate gear position and automatically execute front and rear shifts when riders select a sequentially larger or smaller gear.
Riders can program two customizable shift maps based on terrain and personal preferences. An audible alarm will warn of an upcoming front derailleur shift so that a rider can choose to remain in a given gear
Total control: On a mountain bike with both front and rear Firebolt shifters installed, the rider can manually shift at any time. Synchronized Shift becomes another available tool for riders, not a requirement. With a touch of a button, riders quickly choose between synchronized maps or choose manual mode for complete control
