I am deciding between a Bianchi Via Nirone 7 Alu Carbon. Or a Cannondale Six 5. Normally these wouldnt be my only options but I can get a good deal on either. They both have the Aluminum/carbon rear Triangle. I want something I can eventually ride crits on. It seems that the geometry on the Nirone is a bit more relaxed. Any opinions would be appreciated. Oh, I am also looking at the Aluminum Bianchi1885.
