Wheels Manufacturing Derailleur Hanger

This specific hanger is designed exclusively for the 2009 Commencal Supreme DH. Because derailleur hangers are frame-specific, you must verify your bike's exact make, model, and year before purchasing, as even slight variations in frame geometry will prevent proper installation.

CNC machining allows for extremely precise tolerances, which is critical for a derailleur hanger. A hanger that isn't perfectly aligned will cause poor shifting performance, chain drops, or even damage to your derailleur and drivetrain components.

Yes, 6061 aluminum is an industry standard for derailleur hangers because it offers an ideal balance of strength and ductility. It is designed to be the 'weak link' in your drivetrain, meaning it will bend or break to absorb impact energy, effectively protecting your more expensive frame and derailleur from damage.

The black anodized finish provides a crucial layer of corrosion resistance, protecting the aluminum from oxidation and the elements. This helps maintain the structural integrity of the part over time, ensuring the threads and mounting surfaces remain clean and functional.

It is highly recommended. Because a bent or broken hanger will immediately disable your shifting and effectively end your ride, keeping a spare in your pack is a simple, low-cost insurance policy for any mountain biker.
