Description

The GRX RX717 rear derailleur, paired with a 10-51T 12-speed cassette, gives gravel riders the speed, range, and robustness to pursue any gravel challenge. With built-in Automatic Impact Recovery, an impact-deflecting shape, and solid pulleys, this derailleur stands up to hard impacts and still retains its lightning-quick shifting performance. It also features the same battery featured on GRX RX827, XTR M9250, XT M8250, and DEORE M6250 derailleurs, so you can swap batteries between your mountain and gravel bikes.
Features:
– Fully wireless shifting built for rough gravel terrain
– Robust Design: A wide link structure, skid-plate design, durable aluminum plate and solid pulley add robustness and longevity.
– RD Protection Function: The new Automatic Impact Recovery function instantly returns the derailleur to its original position after impact.
– SHIMANO SHADOW ES: A slimmer, stronger evolution of SHIMANO´s pioneering chain-stabilizing SHADOW RD+ concept.
– Protected Battery: Tucked safely inside an enclosed space, the battery won´t budge even in rough terrain, while remaining easily removable for charging.
