In Italy, since we are talking about Italian bikes, "touring" is nothing like you think. Their Turismo or Viaggio bikes are what you would probably call a city bike. In some cases these Turismo or Viaggio bikes were 1x5 gearing, but many were just single speeds. Pretty much all of them had flat bars. Drop bars were for pretty much for Corsa models only.

That said, from what I have bought for both types of bikes, geometry is similar. The Turismo/Viaggio bikes may have a slightly longer top tube and wheelbase than the Corsa, but without measuring the different models in the same model year, I'd say the geometry is probably the same to lower production costs. The only difference being pretty much all Turismo/Viaggio models probably have straight-gauge tubing where some of the Corsa models had butted tubing. The low-end Corsa models typically had straight-gauge.

Who has the "best" butted tubing? Columbus? Reynolds? Falck? All marketing bs. Again, the bike don't matter.
