Al - a friend of mine is selling her 2008 Bianchi Volpe cyclocross bike - it's too big for her, so she's never ridden it very much, and it's been sitting in the garage since 2010. 55 cm, cro-moly frame, tiagra components. Comes with a set of slicks and a set of knobbies.
Asking $550. I can send over pics if you PM me or email at ihankim -at- yahoo -dot- com.
