Derailleur hangers exist to break. That sounds counterintuitive until you consider the alternative: a bent or cracked dropout on your carbon frame. The Cervelo Derailleur Hanger serves as a sacrificial component, engineered to deform under impact before that force transfers to the frame itself. When your bike tips over in a parking lot, takes a hit from debris, or suffers an unfortunate encounter with a rock, the hanger absorbs the damage so your frame doesn't have to.

Cervelo manufactures frame-specific hangers because derailleur alignment depends on precise geometry between the hanger mounting surface and the derailleur pivot. Generic aftermarket hangers often miss this precision, leading to shifting issues that no amount of cable tension adjustment can resolve. The OEM hanger matches the exact specifications of your frame's dropout, ensuring the derailleur sits at the correct angle relative to the cassette. This matters most with 11-speed and 12-speed drivetrains where tolerances have tightened considerably compared to earlier generations.

Two versions cover the Cervelo rim-brake road lineup. The DRH-R-2003 fits all rim-brake road bikes from 2003 through 2010, while the DRH-R-2012 works with rim-brake road models from 2012 forward. Check your frame's model year before ordering to ensure compatibility. The hangers share the same lightweight aluminum construction and mounting interface design that Cervelo uses across their road platform.... Read More
