On the bay a couple weeks ago was a Paramount with a 60 tooth chainring. A racer I knew in the 70's raced on a bike with 180mm cranks and a 56 tooth chainring. And know days the 10 and 11 tooth sprokets can boost your high gear. I'm a small gear spinner with a top gear of 48/13, but have always been fascinated by bikes setup with monster gears. Anyone running the mongo gear on any of your bikes?
