Frequently Asked Questions

What fits LTWOO R7 Rear Derailleur (RD-R1000-M)?

On this page we list chains for this derailleur, cassettes for this derailleur, shifters that drive 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 R7 Rear Derailleur (RD-R1000-M)?

No. LTWOO R7 Rear Derailleur (RD-R1000-M) 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 LTWOO R7 Rear Derailleur (RD-R1000-M) work with electronic shifting like Di2 or AXS?

No. LTWOO R7 Rear Derailleur (RD-R1000-M) is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
