Frequently Asked Questions

What fits Shimano DEORE XT REAR DERAILLEUR 1X12s (RD-M8100-GS)?

On this page we list shifters that drive this derailleur, cassettes for 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 DEORE XT REAR DERAILLEUR 1X12s (RD-M8100-GS)?

No. Shimano DEORE XT REAR DERAILLEUR 1X12s (RD-M8100-GS) 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 DEORE XT REAR DERAILLEUR 1X12s (RD-M8100-GS) work with electronic shifting like Di2 or AXS?

No. Shimano DEORE XT REAR DERAILLEUR 1X12s (RD-M8100-GS) is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
