Ultegra RX Di2 RD-RX805-GS 11-speed rear derailleur

With the Ultegra RX Di2 rear derailleur, the Japanese manufacturer Shimano moves with the times and expands the Ultegra Di2 high-performance groupset by a drivetrain component that is designed to fit stylish adventure and gravel bikes or cyclocross bikes. The rear mech comes with the proven Shimano Shadow RD+ Technology you know from the MTB sector, where a stabilizer slows down the movements of the RD-RX800 Di2 rear derailleur. Thus, the derailleur does not hit the chain in rough riding conditions, which results in a smooth and silent performance.
