What to Compare Before Buying

  • Drivetrain: Check that your bike uses a compatible 6/7-speed setup. The speed description alone does not establish compatibility with every drivetrain component.
  • Mounting: Confirm that your frame and current derailleur use a compatible direct-mount arrangement.
  • Cage: Compare the medium-cage configuration with your bike’s existing setup rather than assuming cage styles are interchangeable.

Compatibility, Size and Fit

The derailleur is described for mountain bikes and general bicycle repair, but those use descriptions do not confirm fit on a particular bike. Compare the mounting type and drivetrain requirements with your existing setup. If compatibility is unclear, check with a qualified bike technician.

Before You Decide

Confirm the 6/7-speed match, direct-mount fit and medium-cage configuration for your bike. The listed quantity is one derailleur.
