Funny you mention your Volpe -- I think it's the same frame, just with different decals. It's a Valle from '08. The published frame geometry is identical to the Volpe, and the tubing appears to be the same. I decided to convert it once I figured that it would be no more expensive than adding a dynohub wheel and wiring to a Volpe (plus the Valle has wiring guides on the fork, which is nice).
