Shimano GRX RX810 1/2x11 speed

The Shimano GRX RX810 was designed especially for single and double Shimano 11 speed gravel groupsets. This Shimano GRX gravel rear derailleur is silent, shifts smoothly and doesn't rattle on rough terrain! The Shimano GRX 11 speed rear derailleur is also compatible with road bikes with different Shimano 11 speed shifters. In that case, consider classic road cycling routes or tours over bad roads and cobblestones.

Stable due to its clutch
This derailleur comes with an integrated clutch. This clutch keeps the derailleur from rattling when you're riding on rough terrains, and the chain will keep its tension. This also makes sure the derailleur shifts quickly and smoothly, and you won't hear a lot of noise from the derailleur.

Compatible with all 11-speed Shimano shifters
This derailleur is compatible with all 11-speed Shimano shifters. This derailleur is of course compatible with GRX RX180 shifters. These shifters are designed especially to give you as much grip as possible on rough terrain.

Which cassettes are compatible with this derailleur?

• Long cage (GS): 11/28, 11/30, 11/32, 11/34

Crooked derailleur hanger?
Crooked derailleur hangers are a common problem. This happens sometimes if you knock your derailleur hanger into something, for example in case of a fall. Luckily this can be fixed!

Clean your jockey wheels well too!
Just like your chain, the jockey wheels on a derailleur will get dirty. This affects your bike's cycling feel and isn't good for your bike's drivetrain. That's why we recommend cleaning the jockey wheels whenever you clean and lubricate your chain. Do this by running a cloth along the jockey wheel while gently turning the chain. When your jockey wheels are worn out eventually, they'll have to be replaced.
