Compatibility, Size and Fit
The listing describes the shifter for mountain and folding bikes, but bike type alone does not confirm fit. Check that the bike uses a compatible 7-speed drivetrain, that the shifter belongs on the right side, and that the handlebar measures 22.2 mm at the mounting point. A 7-speed rating does not establish compatibility with every 7-speed setup.
What to Compare Before Buying
- Speed and drivetrain: Verify the bicycle’s speed count and compatibility with this shifter. It is not specified for 8-, 9- or 10-speed systems.
- Mounting diameter: Compare the handlebar measurement where the shifter will mount with the specified 22.2 mm.
- Replacement needs: The listed configuration includes a shifter and matching shift cable. Check that this is the side and quantity needed for the repair.
Before You Decide
Confirm right-side placement, the 7-speed drivetrain, and the 22.2 mm handlebar fit. Check compatibility with the specific bicycle before choosing this replacement part.
