Robust, Resilient, Ready for Anything
The centerpiece of this bomb-proof system is the new XTR M9250 rear derailleur, which features a unique low-profile wedge-shaped design that helps it avoid blunt force trauma—like when you cut a high-speed corner just a tad too tight while trying to shave seconds off your enduro race run. And even when the inevitable miscalculation does happen and you bang your derailleur into a sleeper rock, its unique shape and surface materials help it glance off, preventing catastrophic damage. The new derailleur also boasts a wide link structure, tough carbon skid-plate, and solid pulley design that reduces the chances of debris getting jammed inside.
Customisable Di2 Buttons
Carrying over the familiar shape of a traditional shifter, it features four-way multi-axis adjustability where the shift paddles can be placed where you want them. Simply place your thumb in its most comfortable position and move the paddle to meet it.
The new Di2 shifter’s shift paddles also feature a comfortable and tactile feel, and their functions can be customized for different riding preferences using the SHIMANO E-TUBE app. Options include hold-down multi-shift, click-through double shift, and locked-out single shift. There’s even a programmable third button that can be used to scroll through screens of a connected GPS device. Or follow the lead of many SHIMANO pro racers and assign electronic “barrel adjuster” status to the third button. This allows you to adjust derailleur trim on the fly with one hand so you can tune your shifting after a crash without taking your foot off the proverbial gas.
