Campagnolo EPS V4 12-Speed Internal Interface without Cables/Fittings and Cover

Internal interface can be mounted in frame or handlebar end.

Internal interface available for new Super Record EPS groupsets that can be mounted either on the right-hand end of the handlebar or inside the down tube on specifically designed frames. All communication between the Ergopower control levers and the front and rear derailleur components becomes a specific action thanks to the new interface. The V4 version not only receives the electronic impulses and sends them to the front and rear derailleurs; thanks to its two internal aerials, with both Bluetooth Low Energy and ANT +, it can also communicate in real time with a vast range of external devices, ranging from phones to bike computers, through to any other electronic device used by the cyclist.
