Cannondale SuperSlice Rear Derailleur Hanger

You should inspect your hanger if you notice inconsistent shifting, chain skipping, or if the bike has fallen on the drive side. If the hanger appears visibly bent, twisted, or if your shifting performance suddenly degrades after an impact, it is likely time for a replacement.

This specific hanger is designed for the Men's SuperSlice Dura Ace Di2, Red eTap, and Ultegra Di2 models. Always verify your specific frame year and model against the manufacturer's compatibility list, as hanger designs can change between production years.

While some hangers can be realigned using a specific tool, the metal is often weakened during the bending process. Replacing the hanger is the safest way to ensure proper drivetrain alignment and prevent future shifting issues or potential failure.

The derailleur hanger acts as a sacrificial part. It is engineered to fail under stress to absorb the impact energy, which protects your expensive carbon frame and rear derailleur from catastrophic damage during a crash or drop.

Installation typically requires a standard set of hex keys to remove the mounting bolts and detach the old hanger. You will also need to re-index your gears after installation to ensure the derailleur is properly aligned with the cassette.
