Electro-Campy? We offer a first look

Watch your head, because the component war continues to wage at full-fury. First, with Shimano's intentional/accidental shot over the bow with its posterboy Armstrong showing up all big and beautiful in the latest Sports Illustrated sporting next-gen Dura-Ace. And now with Campagnolo granting VeloNews the first detailed images of its much-rumored electronic gruppo.
