Wheels Manufacturing Derailleur Hanger 151

Derailleur hangers are frame-specific, not universal. You must match the hanger shape to your specific bike frame's dropout. We recommend using the Wheels Manufacturing hanger finder tool on their website or comparing your current hanger visually against the photos provided to ensure an exact match.

The Hanger 151 is CNC machined from 6061 aluminum, which is a high-quality, durable material. While it is designed to be a direct replacement that meets or exceeds original equipment specifications, it is still engineered as a 'sacrificial' part. This means it is intended to bend or break during an impact to prevent more expensive damage to your bike's frame.

Yes, this hanger includes the necessary M4x8 flat head screws for installation. You will not need to source additional hardware to mount it to your frame.

If your shifting is poor, a bent hanger is a common culprit. Replacing a bent hanger with this precision-machined part will often restore crisp shifting performance. However, if your derailleur itself is damaged or bent, replacing the hanger alone may not solve the issue.

The black anodized finish is more than just aesthetic; it provides a protective layer that significantly increases the aluminum's resistance to corrosion and wear. This helps the hanger maintain its structural integrity and precise fit even when exposed to moisture and road debris.
