Rear derailleur: what to check before buying

• Number of speeds. Check compatibility between the chain, cassette, derailleur and shifters.
• Component standard. Check the fittings, interfaces and spare-part code of the system fitted to your bike.
• Use and adjustment. Gear selection and adjustment should be assessed across the complete drivetrain.

Unsure about compatibility?

Have the brand, model, year and, if available, the code of the fitted component ready. You can ask the Doctorbike team or contact our certified workshop to assess the work needed.
