Compatibility

LTWOO GRT Shifter (ST-GR1209-R) 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.

Frequently Asked Questions

What fits LTWOO GRT Shifter (ST-GR1209-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 GRT Shifter (ST-GR1209-R) work with electronic shifting like Di2 or AXS?

No. LTWOO GRT Shifter (ST-GR1209-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 GRT Shifter (ST-GR1209-R) compatible with rim brakes?

No. LTWOO GRT Shifter (ST-GR1209-R) is built for hydraulic disc systems. The mounting standards and wheel/frame interfaces for disc brakes are different and cannot be mixed.
