Well here's a pic of the Bianchi. I've been riding steel framed RBs for many years and this one is as light as the aluminum rides. I'm wondering if the sloped geometry is what contributes to its lightness? I also like the adjustable stem, a nice touch. It's a terrific riding and handling bike and it shifts *very, very smoothly*, which is surprising, considering all the negatives I've heard about Sora components. Its even smoother than the 105's on my Trek. I have no complaints.
