Wheels Manufacturing Derailleur Hanger 248

Derailleur hangers are frame-specific, meaning they are designed to fit the exact geometry of certain bike models. You should compare your current hanger visually to the 248 model or check your bike manufacturer's documentation to confirm the correct part number before purchasing.

Yes, this hanger is CNC-machined from 6061 aluminum, which typically offers superior stiffness compared to the softer, cast aluminum hangers often used as original equipment. This increased rigidity can lead to more precise shifting, especially under load.

The black anodized finish provides a durable, corrosion-resistant layer that protects the aluminum from the elements. It helps ensure the part maintains its structural integrity and smooth finish even after exposure to mud, water, and road grime.

Installing a derailleur hanger is a straightforward task that requires basic bike tools, usually just a hex key. However, because the hanger aligns your derailleur, you may need to perform a minor indexing adjustment on your gears once the new part is installed to ensure smooth shifting.

CNC machining allows for much tighter tolerances than traditional casting or stamping methods. This precision ensures the hanger fits perfectly into your frame's dropouts, which is critical for maintaining the correct alignment of your rear derailleur.
