Hey guys i'm looking to build up a flip flop 700cc paired with a front 650cc bike on a bianchi pista frame. obviously the fork is built for a 700cc so i would have to deal without a brake. i guess my question is how will it effect my riding, it's a horizontal top tube so will the smaller wheel drastically change the dynamic of the ride, will buying taller riser bars/taller stem make it so i don't notice it?

this all for aesthetic purposes of course
