Compatibility
LTWOO RX Shifter (ST-R1209-2L) is a LTWOO shifter. It is a 12-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.
RX Groupset7
A groupset is designed and tested as one system, so these are the most reliable match. Other compatible parts are listed below.

Frequently Asked Questions
What fits LTWOO RX Shifter (ST-R1209-2L)?
On this page we list front derailleurs this shifter drives, rear derailleurs this shifter drives. 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 RX Shifter (ST-R1209-2L) work with electronic shifting like Di2 or AXS?
