Derailleur hangers exist to fail. That sounds counterintuitive until you consider the alternative: a derailleur strike that threads into the dropout could crack carbon chainstays, strip threads from aluminum frames, or destroy an expensive rear derailleur. The sacrificial hanger absorbs the impact instead, bending or breaking while everything else stays intact. The Derailleur Hanger 163 from Wheels Manufacturing fits Cervelo road frames from the 2012-2018 era, giving you a direct replacement when the original takes a hit or a spare to carry in your travel case.

Wheels Manufacturing machines this hanger from 6061 aluminum in their Colorado facility, holding the same tolerances as the original equipment part. The profile matches Cervelo's DHR-R-2012 hanger exactly, so derailleur alignment stays where you set it without shimming or adjustment. Black anodizing protects the surface from oxidation and keeps the appearance consistent with stock hardware. Two M3x8 flat head screws attach the hanger to the dropout from the derailleur side, and both fasteners come in the package.

Compatibility spans Cervelo's road lineup from that generation: R2, R3, R5, S2, S3, and S5 models including the Team, CA, VWD, and RCA variants. The same hanger also fits Wilier Air and Superleggera frames from the same period. If you're running one of these frames, keeping a spare hanger makes sense whether you're traveling to races, riding in areas with limited shop access, or just want the security of knowing a minor crash won't sideline your bike for weeks while you source a replacement....
