The SHIMANO RD-RX717 GRX Di2 Wireless Rear Derailleur brings electronic precision to gravel and adventure riding.
This 12-speed derailleur features wireless shifting via integrated battery (BT-DN320 sold separately) with BLE and ANT+ connectivity for seamless gear changes on any terrain. The Shadow ES design includes a low-profile skid plate and dual-spring chain stabiliser that reduces bounce and skipping on rough surfaces. Enhanced spring force keeps chains firmly meshed with sprockets, while 13T solid pulleys and fluorine-coated bushings ensure durability. Crash recovery function protects against impacts, and zero-maintenance performance means reliable shifting mile after mile. Compatible with 40T or 42T chainrings and 10-51T MICRO SPLINE cassettes, it's engineered for drop bar mountain and adventure bikes demanding rugged, responsive performance.
Features
-
SGS long cage for 10-51 cassette: Speed paired with range; the long cage rear derailleur withstands hard impacts on the trail and scores with lightning-fast shifting speed and top-class performance at the same time
-
Low Profile Design: SHIMANO SHADOW ES technology delivers a wedge-shaped design that reduces the derailleur’s front-facing surface area and eliminates edges that could catch on rocks and road debris
-
Automatic Impact Recovery Function: The derailleur absorbs impacts and then automatically resets the rear derailleur, ensuring continued performance
-
Super Strong Design: The rear derailleur body boasts a wide, well-braced linkage and solid pulleys to minimize debris entry and ensure durability
-
New Chain Stabilizing Technology: The dual spring design creates higher chain tension for better chain wrap and retention
-
Battery Protection: Tucked safely inside the rear derailleur body, the sealed battery won’t budge even in the roughest terrain but is still easily removed for charging
