SHIMANO GRX Di2 RD-RX815 Rear Derailleur

The Shimano GRX Di2 RD-RX815 electronic rear derailleur is built for a 2×11-speed drivetrain and can score points with the SHADOW RD+ adjustable chain stabiliser and a quiet, smooth shifting system.

Since the spring tension is adapted to the gravel insert, the GRX Di2 RD-RX815 is particularly suitable for uneven terrain. However, the stabiliser can also be switched off by manual switching directly at the idler pulley, which facilitates wheel removal, for example.

In combination with the matching Di2 shift levers, the gears can be changed almost effortlessly at the touch of a button.

It is perfectly suited for cassettes with 11-30 and 11-34 teeth. In addition, the E-Tube connection makes it possible to read out and update the rear derailleur or adjust it individually.

Please note that the individual components have the same firmware so that there can be no malfunctions.
