Good shifting requires a straight, stiff derailleur hanger. Aftermarket hanger is 100% compatible with Cannondale bikes. Cannondale strongly advises not trying to straighten hangers by bending with a hanger alignment tool.
Kit includes one derailleur hanger and the two tiny screws. Those screws take a 2.5mm hex wrench at installation.
This is the road single sided derailleur hanger that fits most of Cannondale's carbon and aluminum road frames over the past years including (but is not an exhaustive list):
- SuperSix (2008-2013)
- SystemSix
- Six13 Team and Pro
- CAAD9
- CAAD8
- CAADX
- Synapse Carbon (older generations)
- Synapse Alloy (older generations)
