Well, I finally had my Bianchi TSX Reparto Corse frame looked at by a very reputable framebuilder and his conclusion was that the hairline crack I found in the head tube was not serious enough to warrant a rebraze. Some of you may have read some of the tear-drenched threads I posted after finding the crack. I'm not going to have it refinished for now, but I am going to start looking for a component group. The original goal of piecing together an 8spd Campy Chorus group has been squashed by the reality of the cost. And I have also retreated from my original thought that Shimano on an Italian bike would just be wrong. So, I'm asking the Forums' opinions about what component group would be the best quality versus cost for an upper shelf Italian frame?
