Campagnolo 12-speed EPS V4 Power Unit

The Campagnolo 12-speed EPS V4 Power Unit provides long-lasting power to the whole electronic gear system, allowing derailleurs to move accurately and smoothly and maintaining consistent and reliable communications from the Ergolevers. When it runs flat, it can be quickly and easily recharged.

Its small overall size allows it to be mounted inside a seatpost, down tube or seat tube using the provided adaptors, keeping the bike’s aesthetics neat and tidy. It has a waterproof rating of IP67, ensuring that it functions through all weather conditions.
