SHIMANO XTR Di2 shifters SW-M9250-IR 12-speed | I-SPEC EV
The advantages of electronic shifting are obvious. One push of a button and the chain shifts from one sprocket to another in a fraction of a second, regardless of the situation and without any delays or effort. The high-quality XTR shifters with Shimano's Rapid ES technology are also synonymous with precision. The defined pressure points of the rubberized buttons give you the secure feeling of being in control at all times, while their ergonomic arrangement and adjustment options ensure that you always have a firm grip on the handlebars when shifting.
The rear derailleur communicates wirelessly via Bluetooth®. This eliminates the need for complex cabling and makes mounting on an I-SPEC EV-compatible mount very easy. Of course, the Shimano E-Tube app can be used to personalize the switch assignments. Whether single shifting, multi-shifting or button swapping, the system adapts to your preferences. In addition, another small push button can be used to control a bike computer, for example.
SHIMANO XTR Di2 rear derailleur RD-M9250-GS 12-speed | medium-length cage
The advantages of electronic shifting are obvious. One push of a button and the chain shifts from one sprocket to another in a fraction of a second, regardless of the situation and without any delays or effort. The high-quality XTR Di2 rear derailleur is also synonymous with precision.
In combination with the Hyperglide+ cassettes, you will experience unprecedented shifting performance with virtually no noise. The further developed Shadow chain stabilization concept, here called Shadow ES, enables a very slim design and prevents uncontrolled chain slap on rough trails.
The developers paid particular attention to robustness.The narrow, wedge-shaped design of the rear derailleur, which offers 23 mm more ground clearance, as well as the smooth and resistant surface, significantly minimizes the risk of direct impacts and allows impacting objects to literally slide off. However, if small rocks or a root get in the way, the cage can move inwards thanks to the RD protection function and automatically returns to its previous position. This happens so quickly that the rider is unaware of it and can continue at full speed. In addition, the closed pulleys reliably fend off twigs and branches.
In addition to all the positive visual and technical features, you will also be pleased with the low weight. This is achieved through the clever and elegant choice of materials, with aluminum and carbon dominating.
SHIMANO BT-DN320 battery for XTR Di2 rear derailleur RD-M9250
A major innovation compared to the previous Di2 variants is the elimination of the central power supply. This means that cumbersome wiring is no longer necessary, which makes installation much easier.
The small 305 mAh battery is plugged directly into the rear derailleur. There it sits invisibly, protected against loss and supplies it inconspicuously with the necessary energy. Despite the waterproof compartment, it can be removed quickly and easily for charging.
