Frequently Asked Questions

What fits Shimano GRX Di2 REAR DERAILLEUR 11s (FOR 11-30/32/34T)?

On this page we list chains for this derailleur, shifters that drive this derailleur, cassettes 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 11s (FOR 11-30/32/34T)?

No. Shimano GRX Di2 REAR DERAILLEUR 11s (FOR 11-30/32/34T) is an 11-speed component and needs an 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.
