Compatibility
Shimano GRX REAR DERAILLEUR 11s (FOR 11-40/42T) is a Shimano rear derailleur. It is a 11-speed component. It uses cable shifting. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.

Frequently Asked Questions
What fits Shimano GRX REAR DERAILLEUR 11s (FOR 11-40/42T)?
On this page we list shifters that drive this derailleur, chains for this derailleur, cassettes this derailleur can wrap. Each listing was matched on a specification we hold for both parts; anything we could not verify is omitted rather than assumed to fit.
Can I use a higher or lower speed chain with Shimano GRX REAR DERAILLEUR 11s (FOR 11-40/42T)?
No. Shimano GRX REAR DERAILLEUR 11s (FOR 11-40/42T) is a 11-speed component and needs a 11-speed chain. Chains for different speed counts have different external widths and inner-plate profiles, which causes poor shifting or interference with the neighbouring sprockets.
Does Shimano GRX REAR DERAILLEUR 11s (FOR 11-40/42T) work with electronic shifting like Di2 or AXS?
No. Shimano GRX REAR DERAILLEUR 11s (FOR 11-40/42T) is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
