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 not only receives the electronic impulses and sends them to the front and rear derailleurs, but – 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.
