Well, I just ordered a new Bianchi Super Pista frame. I like the aesthetic of the Pista Concept better but they transformed it into the Super Pista. Getting the same size (same geometry) in Celeste. Turns out the Bianchi warranty on aluminum frames is 5 years. This one is over 6-1/2 years old. I'll post photos of the crack later.
My wife said, "Don't you want to upgrade?"
I thought OMG, what an opportunity. However, I believe I need to have a Celeste Bianchi in my life that I ride regularly so I'm sticking with them. I guess I'm lucky that Bianchi USA has one in stock that's my size.
