Gerolsteiner rider Fabian Wegmann is the one rider in the Amgen Tour of California on the latest prototype version of the Shimano Dura-Ace group.
VeloNews spotted it before the start of stage 1 in Sausalito, and got the walkthrough with Gerolsteiner's Michael Rich, a friend and training partner of Wegmann, and the team's directeur sportif in California.
