SHIMANO GRX Di2 Rear Derailleur RD-RX825 | 2x12-speed

Description

SHIMANO GRX Di2 rear derailleur RD-RX825 | 2x12-speed

With the GRX, Shimano launched the first gravel-specific groupset on the market. Since then, the range of applications and the range of gravel bikes has expanded significantly. Shimano has responded to this development by updating the GRX groupset. It now comes with modern Di2 technology and a 12-speed drivetrain. The high level of functionality and quality reflects the Japanese company's many years of experience.
Technically, the GRX Di2 is similar to the current road bike groupsets. The shifting commands are transmitted wirelessly to the front derailleur and rear derailleur. The latter are connected to a central battery, which can be concealed in the seat post, for example. The 12-speed drivetrain has also been adopted and enables a wider gear range. This makes long uphill rides very comfortable even for less trained riders.

The RX825 Di2 rear derailleur has been specially developed for the 2x12 GRX drivetrain and cassettes with 11-34 or 11-36 teeth for Shimano Road freehub bodies, giving you a very wide range and a very finely graduated gear ratio at the same time. Thanks to the built-in Shadow RD+ chain stabilizer, the chain remains securely on the chainring even on the roughest gravel trails. What's more, gear changes have never been so quick. At the touch of a button, the chain shifts from one sprocket to the other in a fraction of a second, regardless of the situation, thanks to the powerful and reliable integrated motor. The system is also supplied with new energy via the rear derailleur. The charging cable is plugged into the small charging port and after approx. 1.5 hours you can get back in the saddle. A small LED reliably indicates the remaining capacity. With the help of the Shimano E-Tube app, the rear derailleur is fine-tuned after installation and a manual, fully or semi-synchronous shifting mode is selected depending on your preference. The narrow Shadow profile reduces the risk of damage in the event of a fall.
