Shimano rear derailleur GRX RD-RX717 Di2 12 speed SGS type MTB

Description

With the SHIMANO GRX RD-RX717 rear derailleur, your gravel bike gains calm, confident shifting even on rough gravel. Gear changes are instantaneous, so you can focus on your line and riding rhythm.

Main benefits

Di2 electronic shifting works fast and quietly, even when you’re climbing or accelerating out of a corner. The response is precise, because the chain moves to the selected sprocket with a single press.

The SHADOW ES design keeps the derailleur close to the frame and helps stabilize the chain off-road. The result is less rattling and smoother drivetrain operation on rocky tracks.

The long-cage SGS version handles a wide gear range for adventure rides. It reliably copes with demanding route profiles where fast sections alternate with steep climbs.

The auto-return-after-impact function helps when you hit an obstacle. The derailleur deflects and quickly returns to the correct position, keeping shifting usable.
