I have a Bianchi Pista right now with B43 rims right now and I am thinking of lightening up my frame. I realize the wheels are heavy, but I want to try them out on an aggressive aluminum track frame. I've compared the geometries of the Super Pista and the Cinelli Mash, the two primary frames I am considering. The Bianchi seems to have a little tighter geometry on paper, but how do they differ in handling, climbing ability, sprinting, absorbing bumps in the road, and any other advise you could give to enlighten my decision. Thank you!
