Check the bike’s drivetrain speed and confirm compatibility with its shifter and cassette. Verify the required mounting interface against the bike and the derailleur’s specifications. The listed speed range alone does not confirm fit across different bikes.
Before You Decide
Match the speed setup, shifter and cassette compatibility, and mounting interface. Check the listed dimensions and confirm that one derailleur is the quantity you need.
