Shimano GRX REAR DERAILLEUR 12s (FOR 11-34/36T) Compatibility Guide

Quick Verdict

Shimano GRX REAR DERAILLEUR 12s (FOR 11-34/36T) is a Shimano rear derailleur. It is a 12-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.

How this list is built: a part is listed only when we hold the specification that decides the pairing for bothparts and those specifications match: the freehub body for a cassette and a wheel, the mounting interface for a chainring and a crankset, and so on. Each card shows exactly what was compared. Where we do not hold that specification the part is left out rather than assumed to fit, so this list is deliberately incomplete rather than speculative. Always confirm against the manufacturer’s own compatibility documentation before buying.

Frequently Asked Questions

What fits Shimano GRX REAR DERAILLEUR 12s (FOR 11-34/36T)?

On this page we list cassettes this derailleur can wrap, shifters that drive this derailleur, chains for this derailleur. 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 12s (FOR 11-34/36T)?

No. Shimano GRX REAR DERAILLEUR 12s (FOR 11-34/36T) is a 12-speed component and needs a 12-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 12s (FOR 11-34/36T) work with electronic shifting like Di2 or AXS?

No. Shimano GRX REAR DERAILLEUR 12s (FOR 11-34/36T) is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
