Campagnolo.Chorus 11 EPS V2 Power Unit

Working in conjunction with the Chorus EPS V2 Interface brain, the Campagnolo Chorus 11 EPS V2 Power Unit is the heart of the system. It's the battery, but also more, utilizing Campy's Digital Tech Intelligence (DTI) to work with the Interface to calculate derailleur functions like shifting and alignment, and project remaining charge life (indicated on the Interface's color LED display). The unit's cylindrical shape allows it to be installed externally or inside seat tubes, whether round or aerodynamically-shaped. For internal installations, a specially-engineered casing has been designed to absorb impacts and road vibrations to ensure long component life and reliability, while there's also an "input/output gate" on the battery for battery charging and firmware updates. The Chorus V2 Power Unit weighs roughly 130 grams and uses a connector system than can only link with Chorus and Athena EPS systems, not Record or Super Record EPS systems.
