Wheels Manufacturing Derailleur Hanger Dropout 652

Derailleur hangers are frame-specific, not universal. You must visually compare your current hanger to the photos of the 652 model or check the Wheels Manufacturing compatibility guide using your bike's make, model, and year to ensure an exact match.

The hanger acts as a sacrificial fuse for your drivetrain. By bending or breaking during a crash or impact, it absorbs the force that would otherwise destroy your frame's derailleur mount, which is often a permanent, non-replaceable part of the frame.

Wheels Manufacturing hangers are typically machined from 6061 aluminum, which often exceeds the quality and precision of the original cast or stamped hangers provided by many bike manufacturers. This results in stiffer, more reliable shifting performance.

Installation is straightforward and usually requires only a set of hex keys to remove the mounting bolts from your frame. However, once installed, you may need to perform a minor derailleur adjustment or use a derailleur hanger alignment gauge to ensure the shifting remains crisp.

Yes, it is highly recommended. Because the hanger is designed to fail to protect your frame, a bent or broken hanger will immediately disable your bike's ability to shift gears, effectively ending your ride unless you have a replacement on hand.
