Shimano XT Di2 RD-M8050 11-speed Shadow Plus Rear Derailleur

The XT Di2 RD-M8050 rear derailleur by Shimano - powerful and high-precision

The electronic Shimano XT Di2 RD-M8050 rear derailleur impresses with a super powerful servo motor and shifting at the touch of a button, which is highly accurate even under extreme load or in difficult conditions. The Synchro Shift function allows the front derailleur to make automatic movements according to the position of the rear derailleur, making it even easier to use and preventing possible cross chaining. In addition, the Shadow Plus stabilizer provides friction damping and optimum chain stability. The RD-M8050 is made of aluminium and is only available with a short GS cage, which shifts cassettes up to 11-42 (2x11-speed) or 11-46 (1x11-speed).

Technology:

Digital Integrated Intelligence (Di2)
Di2 systems are the electronic shifting systems from Shimano. They are based on the SEIS, the Shimano Electronic Intelligent System, which takes over the index shifting function from the mechanical components, only via power cables or radio signals and not via a Bowden cable. Shifting is done by simply pressing a button. This has the advantage that no great effort is required, your concentration on the ride is not disturbed and operation is easy even with cold hands. In addition, the electronic gear changes are very fast and highly precise. There is also no risk of a defective circuit due to dirty cables or other problems. You can adjust individual settings via the E-Tube Project, such as adjusting the shifting speed, the number of shifting operations per button press or the Synchro or Semi-Synchro shifting function. Shimano offers an app for this purpose. Gear maintenance and firmware updates are also done via E-Tube, with the bike connected to a PC running the appropriate E-Tube software for more extensive workshop work.

Shimano Synchronized Shift
Shimano's synchronised shifting function is a shifting mode that automatically matches the Di2 rear derailleur and Di2 front derailleur. It is activated either via the E-Tube platform or via the rear derailleurs with a function button. Synchro Shift means that the front derailleur automatically selects a suitable gear depending on the position of the rear derailleur, while Semi-Synchro Shift means that a suitable rear derailleur position is automatically set when you operate the front derailleur. This gives you the advantage that you only have to concentrate on one side of the shifting process and are not thrown off-rhythm by sudden unfavourable changes to the gear ratio.

Shadow RD+
Shadow Plus rear derailleurs are just as low-profile as Shimano's Shadow rear derailleurs. In addition, a stabilizer with on/off switch is used to reduce chain slap and thus counteract chain drop. At the same time, this results in a quieter drive. Weight is also saved compared to other chain restraint devices.
