Compatibility
LTWOO EGR Rear Derailleur (RD-EG1201-M-A) is a LTWOO rear derailleur. 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 EGR Rear Derailleur (RD-EG1201-M-A)?
On this page we list chains for this derailleur, cassettes this derailleur can wrap, 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.
Does LTWOO EGR Rear Derailleur (RD-EG1201-M-A) work with electronic shifting like Di2 or AXS?
No. LTWOO EGR Rear Derailleur (RD-EG1201-M-A) is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
