Compatibility
Shimano GRX Di2 DUAL CONTROL LEVER 2x12s is a Shimano shifter. It is a 12-speed component. It uses Electronic (Di2) 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.
