Frequently Asked Questions

What fits Shimano GRX Di2 REAR DERAILLEUR 2x12s?

On this page we list cassettes for this derailleur, 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 Di2 REAR DERAILLEUR 2x12s?

No. Shimano GRX Di2 REAR DERAILLEUR 2x12s 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.
