Shimano GRX Di2 RD-RX825 rear derailleur

Like Shimano's electronic road 12-speed derailleurs, the GRX 12-speed electronic rear derailleur has an integrated wireless connectivity unit and charging port, which ensure fast and reliable shifting and easy charging. The integrated Shadow RD+ technology, already proven in the MTB sector, prevents chain slap and ensures precise shifting even on uneven terrain. Thanks to the integrated ON/OFF lever, the reduction of the chain tension (lever in the OFF position) makes wheel removal for transport, service, etc. much easier. The RD-RX825 rear derailleur is compatible with 11-34T and 11-36T 12-speed cassettes and supports fully or semi-synchronized shifting modes, which improves individual adaptation to the rider. The derailleur cage handles a total capacity of up to 40 teeth.
