Derailleur hangers exist to bend or break before your frame does. When your bike falls over in a parking lot or your rear derailleur catches a stick, the hanger absorbs that impact and deforms instead of transferring force into your dropout threads or carbon structure. The Wheels Manufacturing Derailleur Hanger 330 replaces the factory hanger on Cervelo disc road frames including the C3, C5, and R3 Disc models, restoring proper derailleur alignment after the inevitable incident that leaves your original hanger tweaked.

A bent hanger causes shifting problems that no amount of cable tension adjustment can fix. The derailleur mounting tab sits at the wrong angle, which means the jockey wheels don't track correctly through the cassette. Ghost shifts, hesitation under load, and noise all trace back to hanger alignment in many cases. If your Cervelo has been shifting poorly since a crash or tip-over, the hanger is the first thing to check. Carrying a spare on longer rides or during travel makes sense given how quickly a bent hanger can end your day.

This hanger fits Cervelo disc brake frames that use standard thru-axle wheels with M12x1.75 threads. One important compatibility note: it does not work with Cervelo's R.A.T. (Rear Axle Through) system, which uses a different dropout interface. If your Cervelo has R.A.T. axles, you need a different hanger. The part replaces Cervelo's DRH-WMN112, so you can cross-reference against your frame's documentation if you're unsure which system you have.... Read More
