Wheels Manufacturing Derailleur Hanger 148

Derailleur hangers are frame-specific components. Because every bike frame has a unique dropout shape and mounting interface, you must use a hanger designed specifically for your bike's make and model to ensure proper shifting alignment and structural integrity.

CNC machining from 6061 aluminum creates a much more precise and consistent part compared to cast alternatives. This precision ensures your derailleur sits at the exact angle required for crisp, reliable shifting.

Yes, this hanger includes the necessary mounting hardware, specifically two M4x8 flat head screws, so you can install it immediately without hunting for compatible fasteners.

This hanger is compatible with a range of models from brands including BH, Bianchi, Blue, Deng Fu, On One, UNOVELO, and Van Dessel. Because compatibility can vary by year and specific frame version, we strongly recommend verifying your bike's specific hanger ID against the manufacturer's compatibility chart before purchasing.

The derailleur hanger acts as a sacrificial fuse for your bicycle. If your bike takes an impact on the rear derailleur, the hanger is engineered to bend or break first, protecting your expensive frame from catastrophic damage.
