David Bonzon rides a trials bike and only happens to be the best in Switzerland. And Europe. And in the world. Yep, he holds the world champ titles in all three junior categories. He lives only an hour away from the Epic headquarters, so we asked him to give us a tour of his hometown of Montreux, Switzerland. He took us to one of the most unlikely trial spots, the Chateau de Chillon, and this is what happened.
