Dear Bianchigirll,

For more information, the Columbus sticker on seat tube said "Profilo S4 Glico Design" is this help? I'll upload more photo of this frameset, especially dropouts.

Is this frame looks like this one? http://www.flickr.com/photos/5237566...n/photostream/

By the way, Front wheel is 650c for sure, will change it to Campy Shamal 700/650 wheelset soon

Thank you for your helpful answer!
