Shimano RD-RX815 GRX Di2 Rear Derailleur

Gravel riding has been taken to new levels in the past years. What used to be a niche cycling event for the rebels and rule breakers has taken to the masses, with events that are packed with faces from all walks of cycling life, from the avid endurance athlete to the roadie, and everything in between. And with such growth, it doesn't surprise us at all that Shimano made its debut into the gravel scene recently with its launch of a gravel-specific groupset. Now, bringing things even further into the future, Shimano offers its GRX group with a little bit of Di2 magic dusted on top, and the GRX RD-RX815 Di2 Rear Derailleur is ready to hold things down in the rear end. The GRX Di2 rear derailleur takes the shape and tech that we love from the standard GRX rear derailleur, like the clutch mechanism that secures your chain on rough roads, and ads in electronics for crisper shifting than before.


*Shimano brings Di2 to the gravel scene with this sleek new derailleur

*Shadow clutch mechanism increases spring tension to eliminate chain slap

*Clutch is easily flipped to make wheel changes and flat fixes a breeze

*Derailleur cage tucks closer to frame to avoid hits and bumps

*Compatibility for both 1x and 2x drivetrains

*Durable alloy construction handles mud and off-road adventures

*Works with current Shimano 11-speed road shifter/brake levers

*Low-profile Shadow design helps avoid damage from impacts

*Electronic shifting is smooth, crisp, and precise

*Short cage accommodates up to a 34t sprocket, look to the 812 series for larger cassette needs
