I recently started riding a norco triathlon (tange). It is a bike out of my free bike program cause all mine have flats. I think ive fallen in love with the 700c with low CG, this bike is just such a pleasure. I am really questioning the frame I am about to hand build. The plan was designed around 26's. Is it the low cg that is getting me, or do you experienced tourers really find a big difference between 26 and 700 in terms of rolling resistance and stability?
