Shimano Di2 M8250 SGS Upgrade Kit

SW-M8250 shifter: the perfect gear shift solution
The XT M8250 shifter features the same technologies as the XTR version, its bigger brother. With two versatile shift buttons that are adjustable in height as well as rotation direction, the shifter can be customised to the user's hand shape and size. This ensures optimal control and comfort on every ride, whatever the conditions.

Sophisticated technology for today's mountain bikers
The programmable third button on the shifter gives you complete freedom in terms of function allocation and can easily be set via the E-TUBE app. Whether you want to use it to operate your bike computer or for other e-functions, the SW-M8250 gives you the technology you need. The shifter has a rubber grip surface and is available in two mounting options: I-SPEC EV for a sleek finish and ease of use, or a clamping strap.

RD-M8250 rear derailleur
The XT M8250 rear derailleur is a fully wireless derailleur. Its battery is well concealed and covered inside the derailleur and, therefore, protected from any impacts and weather influences. The derailleur has been designed to withstand any form of impact and has a special impact-deflecting shape that makes it quite flexible. Thus, in case of an impact, the derailleur automatically and instantly returns to its original position to continue the ride as if nothing has happened. The jockey wheels are completely covered, so nothing can get caught in them. The long cage is made for the 10-51 cassette, and the medium cage is compatible with the 9-45 cassette.

Battery, charger and quick link
The compact 310 MaH battery will last at least 300 kilometres. It is perfectly concealed inside the derailleur and can be easily removed for charging. The charger is included in the kit, as is a USB-C cable. Since the chain has to be disconnected for derailleur installation, a new quick link is also included.

Material and construction
The rear derailleur in the XT M8250 upgrade kit has been designed using the proven Shadow ES technology, which not only makes gear shifting fast and direct but also quiet and stable. The robust aluminium design offers an optimal balance between durability and weight, allowing the derailleur to withstand tough conditions. The built-in Di2 battery ensures a constant power supply, and the construction aims for reliability in variable conditions. This combination makes the system not only solid but also efficient in power management, so you can enjoy smooth shifting performance for a long time without interruption.

Extras and unique details
As the SW-M8250 shifter features Rapid ES technology, gear shifting feels extremely intuitive and direct. The wireless design makes the cockpit sleek and uncluttered, without any excess cables. The BT-DN320 battery and EC-DN100 charger are a perfect match, making charging easy and efficient. The Quick Link SM-CN910-12 makes chain connection easier and faster, saving time during maintenance or mounting. The combination of these parts results in an upgrade kit that is not only technically advanced but also practically well developed in terms of use and maintenance.

For a 10-51 cassette, you need the long cage. The 9-45 cassette is compatible with the medium cage. Swapping is not possible.

The upgrade kit is compatible with the 6100/7100/8100/9100 MTB groupsets.
