Cervelo Hanger Direct Mount Shimano / DRH-SDM

The Cervelo DRH-SDM is a genuine Shimano direct mount derailleur hanger designed for Cervelo disc brake road and gravel frames. Engineered to provide a clean, stiff interface for Shimano direct mount rear derailleurs, this hanger delivers precise alignment and consistent shifting performance across a wide range of mechanical and Di2 drivetrains.

By eliminating the need for a B-link adapter, the direct mount design improves derailleur rigidity and shifting accuracy under loadideal for performance road and gravel riding.

Supplied with mounting hardware, the DRH-SDM is the correct replacement hanger for a broad range of Cervelo disc brake models produced from approximately 2015 onward, ensuring compatibility with Shimanos direct mount derailleur standard.
