Wheels Manufacturing Derailleur Hanger 528

This hanger is specifically engineered for the Rock Machine Catherine 70 (2020) and the YT Tues MK2 CF (2015-2018). Because derailleur hangers are frame-specific, we strongly recommend visually comparing your current hanger to the product images or checking your bike manufacturer's specifications before purchasing.

Yes. While stock hangers are often made from softer materials designed to bend easily to protect your frame, this Wheels Manufacturing replacement is CNC machined from 6061 aluminum. It offers a more precise fit and increased durability compared to many standard cast or stamped options.

The hanger is designed to mount using your existing axle nut. It does not include additional mounting bolts or hardware, so you should retain the original hardware from your current setup.

The black anodized finish is more than just an aesthetic choice; it provides a hardened surface layer that significantly improves the component's resistance to corrosion and wear. This is particularly beneficial for mountain bikes frequently exposed to mud, grit, and moisture on the trail.

If your current hanger is bent or misaligned, replacing it with a precision-machined part like this one can often resolve persistent shifting problems. However, if your derailleur itself is damaged or your cable tension is incorrect, a new hanger may not solve the issue on its own.
