For TT Bikes.

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.
