What to Compare Before Buying
- Drivetrain: Check for a 6- or 7-speed SIS INDEX setup. Matching the number of speeds alone does not confirm that every part of a drivetrain will work together.
- Sprockets and capacity: Compare the bike’s smallest and largest sprockets with the stated ranges, and check its required total capacity against 43T.
- Mounting: Verify the derailleur’s direct-mount and wheel-nut bracket arrangement against the bike’s existing mount.
Compatibility, Size and Fit
Broad claims of use on different bike types do not establish fit on a particular bicycle. For a replacement, check the drivetrain and mounting details against the bike and component instructions. Have installation and adjustment checked against those instructions.
Before You Decide
Confirm the drivetrain type, sprocket sizes, required capacity and mounting arrangement. These details matter more than a general match by bike category.
