Mount it up.
There are some frames that won't accommodate internal mounting, and there are also those who simply prefer the battery access an external mount provides. For these scenarios, Campagnolo has developed a new External EPS V2 Power Unit Holder. The durable bracket features six holes that enable a variety of external mounting positions along both axial and radial planes.
The Campagnolo External EPS V2 Power Unit Holder is only compatible with the new V2 Power Unit. It comes in one color and one size.
