Although as a devoted Tarmac rider I might be a bit prejudiced, I really like this ad from Specialized featuring Paolo "the Cricket" Bettini riding really fast at home in Tuscany, wearing the whole rainbow ensemble of the World Champion. The sun is shining, the villages are beautiful, the kids worshipful. There is even an accordion playing.
Paolo looks great. Sometimes it is just a question of La Bella Figura and I think this ad captures it. I even like it when he says, in the only English he speaks in the ad, "I yam Specialized" at the end.
