Frequently Asked Questions

What fits Shimano SAINT REAR DERAILLEUR 10s?

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 SAINT REAR DERAILLEUR 10s?

No. Shimano SAINT REAR DERAILLEUR 10s is a 10-speed component and needs a 10-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 SAINT REAR DERAILLEUR 10s work with electronic shifting like Di2 or AXS?

No. Shimano SAINT REAR DERAILLEUR 10s is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
