Compatibility
LTWOO GR9 Shifter (ST-GR1109-R) is a LTWOO shifter. It is an 11-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.
GR9 Groupset6
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 GR9 Shifter (ST-GR1109-R)?
On this page we list handlebars with a matching shifter mount type (not clamp fit), 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 GR9 Shifter (ST-GR1109-R) work with electronic shifting like Di2 or AXS?
No. LTWOO GR9 Shifter (ST-GR1109-R) is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
Is LTWOO GR9 Shifter (ST-GR1109-R) compatible with rim brakes?
No. LTWOO GR9 Shifter (ST-GR1109-R) is built for hydraulic disc systems. The mounting standards and wheel/frame interfaces for disc brakes are different and cannot be mixed.
