On my everyday bike, (literally never ride another bike) i carry ~25lbs across my rear rack and wald baskets (ontop not in).

Right now I have a 26" bike but I was wondering if anyone has noticed a difference between having weight up higher on a 700c bike. I imagine it would be less stable but im curious as to others experiences.

Im building/getting a new bike and i'm contemplating getting 700c instead of 26"
