This hanger is specifically engineered for select Rocky Mountain frames. Because derailleur hangers are frame-specific, we strongly recommend comparing your current hanger visually to the product photos or checking your bike manufacturer's compatibility chart before purchasing.

Yes, this is CNC-machined from 6061 aluminum, which often provides a more precise fit and better durability than standard cast or stamped factory hangers. It is designed to be a direct, high-quality replacement that maintains the exact tolerances required for crisp shifting.

Yes, the kit includes the necessary mounting hardware, specifically the M8 chainring bolt, to get your derailleur securely attached. You won't need to source additional bolts to complete the installation.

The black anodized finish is applied to provide enhanced corrosion resistance and protection against the elements. While it is durable, it is a surface treatment and can show signs of wear over time, but it will maintain its clean look much longer than raw aluminum.

If you have basic mechanical skills and the correct hex keys, this is a straightforward installation. Just ensure your derailleur is properly aligned and indexed after you bolt the new hanger into place to guarantee smooth shifting.
