To answer all the questions...
It is a 53cm frame size. It does look small to me too. That was my first thought when I saw it. But is fits me perfectly
The saddle bag is an Axiom Road Journey ( that is what is says on the bag). Got it at Universal Cycles. It is the perfect size--not too big or too small.
I bought the bike in Hazel Park, MI at Continental Bike Shop. It is kind of far from me, but so worth the drive. You are right ..... Not many places sell Bianchi. They only special order them at Continental.
