External EPS V4 Interface
Brand: Campagnolo
External version of the Campagnolo EPS V4 interface unit, for frames with no internal housing. It fills the same role as the internal interface — taking the impulses from the Ergopower levers and driving the derailleurs — but mounts outside the frame. Campagnolo quotes 33 g including wires and lists it as compatible with the internal V3 and V4 EPS Power Units.
