actually, tires would be more more expensive. if i get the bike i described above, it will be a straight-up trade. so it will cost me nothing.
if i try to put knobbies on my Legato, can someone recommend me some decent, not over-expensive dirt tires? i have 700x28s on there now, and i don't think a tire that's much larger will fit in my chainstays, so a 700x32 might be the widest.
basically, i want to turn my bike into a flat-bar cyclocross bike and ride it through wooded dirt trails. the dirt around here is really rocky, so i am just afraid this will be a wasted effort because the rigidity of my bike will rattle itself to pieces on those rocky trails.
