Compatibility

LTWOO A3 Rear Derailleur (RD-A0810-S) is a LTWOO rear derailleur. It is an 8-speed component. It uses Cable 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.

Frequently Asked Questions

What fits LTWOO A3 Rear Derailleur (RD-A0810-S)?

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 LTWOO A3 Rear Derailleur (RD-A0810-S)?

No. LTWOO A3 Rear Derailleur (RD-A0810-S) is an 8-speed component and needs an 8-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 LTWOO A3 Rear Derailleur (RD-A0810-S) work with electronic shifting like Di2 or AXS?

No. LTWOO A3 Rear Derailleur (RD-A0810-S) is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
