This clamp adapter converts any Campagnolo braze-on front derailleur into a band-on setup for frames without a braze-on tab. The thirty-five millimeter diameter fits standard road bike seat tubes and works across the full range of Campagnolo electronic and mechanical groupsets from Record and Super Record down through Chorus EPS and Potenza. If you have a frame that requires a clamp-on derailleur but prefer the features of a braze-on model, this adapter bridges the gap without compromising shifting performance.

The adapter uses anodized aluminum construction with an asymmetric clamp design that closes evenly around the seat tube. The mounting bolt sits nearly tangential to the tube, which distributes clamping pressure uniformly rather than creating a single point of stress that could mark the frame. The derailleur tab machined into the adapter maintains the same interface geometry as a frame-mounted braze-on tab, so cable pull and cage positioning work exactly as intended.

Campagnolo includes the frame fixing bolt with the adapter. The company specifies 7Nm of torque for the mounting bolt, which secures the adapter to the frame without risk of slippage during shifts under load.
