Yup, I have that barcelona and one that I made myself out of a pinto/kromag frame.
I found alot of parts through various sites, even some personal contacts, but whenever I was on the monza spain forums they did not want to deal with me for some reason.
Actually had some great email convo's and lined up some parts but when it came time to get the deal going, they bailed. Ebay.se is gabage, but there are alot of whole monza's like ours for cheap but like I said no one wants to deal with it. :(
Email me, id be more than happy to compare notes and find parts or combine shipping if more good deals are to be had.
