Wheels Manufacturing Derailleur Hanger 651

This hanger is specifically designed as a replacement for Orbea Hanger #51/X259. Because derailleur hangers are frame-specific, we strongly recommend visually comparing your current hanger to the product photos or checking your bike manufacturer's specifications before purchasing.

Yes, it includes two M4x8mm flat head screws, so you have everything you need to mount it to your frame right out of the package.

Derailleur hangers are engineered to be a 'sacrificial' part. By using 6061 aluminum, the hanger is designed to bend or break during an impact, which helps absorb the force and protect your bike's more expensive frame and derailleur from damage.

While it provides a clean, stealthy aesthetic, the primary purpose of the anodized finish is to add a layer of corrosion resistance, helping the part withstand exposure to the elements and road grime.

You will typically only need a standard hex key (Allen wrench) to remove the old screws and secure the new hanger. It is a straightforward bolt-on installation.
