Re-configured the Volpe with Dura Ace hubs and Velocity A23 rims, and replaced the very heavy cassette with a 105 cassette.
Now the fundamental difference between our bikes is the crank; my Ritchey has an Ultegra triple, and the Volpe has a Tiagra triple.
The Volpe is still noticeably heavier...the frame seems to be the source of most of the weight at this point. But it is noticeably lighter than it was.
I think the Ritchey would do exactly as well as the Volpe on tour. The Volpe's only advantage is the mid - fork eyelets.
