It teaches you how to pedal smoothly in a complete circle. You probably only push down and and don't realize it. It teaches you to spin faster. I can hit 160 rpm for a few seconds and pedal 100-110 comfortably. It's more pure and simple than having 20-30 gears...almost like driving an American muscle car as opposed to a caddy...unless your Colnago is a custom steel job handmade in Italy (not Taiwan like most of their bikes now) I'm not impressed.
