Shimano GRX Di2 RX827 Rear Derailleur 12S Long Cage
- EAN 4550170290603
- Brand: Shimano
- Product Model: 891888
The Shimano GRX RD-RX827-SGS brings fully wireless Di2 1x12 shifting to gravel, combining a slim SHADOW ES low-profile design with a wide-link, skid-plate body, robust pulleys, and a protected in-housing battery for fast, precise shifts and exceptional durability on rough, muddy terrain. An Automatic Impact Recovery function snaps the derailleur back to position after a hit, allowing you to maintain confident chain control across a 10-51T cassette within a cohesive Shimano GRX groupset.
- Wireless Shimano GRX Di2 12-speed shifting delivers instant, accurate gear changes tailored for gravel adventures and racing.
- The SHADOW ES architecture stabilizes the chain with a slimmer, stronger profile for quiet running and reliable retention on rough tracks.
- A wide-link structure with skid-plate protection and solid pulleys enhances toughness and longevity when the course gets rocky and muddy.
- Automatic Impact Recovery returns the mech to its correct position after an impact to preserve shifting performance when you clip a rock.
- A protected, easily removable battery sits safely inside the derailleur housing to stay secure on washboard and chunder.
- Compatibility with 10-51T wide-range cassettes provides you with the gears to tackle steep climbs and maintain speed on flat sections.
- Seamless integration within a Shimano GRX groupset / Shimano gravel group keeps the cockpit tidy and the ride feel consistent.
