Track racing bike-build

That's a pretty wild claim. are you saying a touring frame or cross frame would ride like a track frame if you get contact points in same place?

I can only speak from experience, and I haven't ridden either of those. Road my new Vigorelli (@Saindsbury's Ed not Mash, sans spoks ;)), and didn't notice anything that I could attribute to a difference in geometry. The one thing I did notice was the bars supplied with it (Cinelli Vai XL) are far too wide, and far too shallow a drop and will be changed toot suite for some Nitto track drops I've been using for the past few years
