The GRX groupset’s rear derailleurs are also unique in accommodating very wide cassettes up to a maximum 11-51 for the 1×12-speed variant, although only up to 42 teeth for 1×11-speed.
Automatic Impact Recovery: this returns the derailleur instantly to its original position after an impact.
Wide link structure and skid plate: the wide links provide added strength and the skid plate helps protect the derailleurs' internals if the bike is dropped.
Shadow ES technology: the lower-profile, wedge-shaped design increases ground clearance and frontal area. The derailleur also features a chain-stabilising clutch to reduce bounce and chain slap.
Protected battery housing: keeps the battery tucked away and out of harm, while providing easy access for charging.
"CUES for recreational road and gravel riding has 9, 10 and 11-speed options with the right, wide-range gears for confidence in the mountains, on descents, through forest paths, and in the city."
