Front derailleur adapter clamp designed to secure mechanical front derailleurs on frames without a dedicated braze-on, improving shift stability and ride confidence. Key benefits Secure hold: Firmly clamps the front derailleur so it resists being pushed or knocked out of position, reducing chain rub and missed shifts. Improved shifting performance: A stable derailleur position delivers more consistent, reliable gear changes and reduces drivetrain wear. Lightweight and durable: Made from corrosion-resistant aluminium alloy with a hollow design for high strength at low weight. Easy to install and remove: Simple clamp design requires no complex tools or procedures and can be fitted by one person—ideal when working with soldered/brazed derailleurs. Size options for fit: Available in two sizes so you can choose the clamp that best matches your frame and derailleur setup. Function and compatibility Purpose: Holds a mechanical front derailleur in the correct position on frames that lack a compatible braze-on mount. Compatibility: Designed for front mechanical derailleurs and frames with soldered or brazed derailleur mounting requirements. Select the appropriate clamp size for your frame diameter. Practical uses Daily commuter bike: Replace a worn clamp or add a secure mount to a non-braze-on frame to prevent shifting problems during city rides. Weekend road rides: Stabilize the front derailleur for smoother chain transitions and fewer interruptions on group rides or long training sessions. Light off-road and gravel use: Keep the front derailleur firmly positioned over rough terrain to minimize chain rub and improve drivetrain reliability. What you get A reliable aluminium alloy front derailleur adapter available in two sizes A simple-to-fit solution for installing or stabilizing mechanical front derailleurs on frames with soldered mounts Choose the correct size for your frame to ensure a tight fit and optimal shifting performance.
