Compatibility

Shimano DEORE REAR DERAILLEUR 2/11, 1X10, 2X10s is a Shimano rear derailleur. 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.
