Hello again.. I originally started this post back on 5-6-13...Well anyway an update, I have converted my bike to a 3 speed (Shimano hub) 44 teeth on crank and 20 on the hub...it felt like second gear was the same as when it was a single speed...so I put a 40 tooth on the crank and it is just what I wanted...now third gear is like the single speed was and have two lower gears for the hills or lite cruising...thanks again to all. 1.75
