Shifters & Derailleurs

SHIMANO Deore XT Di2 rear derailleur RD-M8250-SGS 12-speed | long cage

Since the Deore XT groupset revolutionized the mountain bike world in 1980, it has been synonymous with reliability, durability and functionality. Over time, it has been continuously optimized and improved and is still considered a pioneer in the bicycle industry. Nevertheless, Shimano still managed to make a big leap forward with the Di2 M8200 version. Thanks to modern wireless control, perfect performance, a 12-speed drivetrain and the usual outstanding build quality, there are no limits to your cycling dreams and you have a loyal companion for your adventures.

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 first-class Deore XT 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.
The power supply to the rear derailleur is also a small revolution. For the first time, Shimano is using a decentralized battery, which is well protected inside the derailleur and can be easily removed for charging.
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 high-quality aluminum dominating.

Note: The battery is not included in the scope of delivery, but can be purchased separately in our store.

SHIMANO Deore XT Di2 shifters SW-M8250-IR 12-speed | I-SPEC EV

Since the Deore XT groupset revolutionized the mountain bike world in 1980, it has been synonymous with reliability, durability and functionality. Over time, it has been continuously optimized and improved and is still considered a pioneer in the bicycle industry. Nevertheless, Shimano still managed to make a big leap forward with the Di2 M8200 version. Thanks to modern wireless control, perfect performance, a 12-speed drivetrain and the usual outstanding build quality, there are no limits to your cycling dreams and you have a loyal companion for your adventures.

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 Deore XT 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 3-way adjustment options ensure that you always have a firm grip on the handlebars when shifting.
Communication with the rear derailleur is wireless 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, 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.
