Seems a single speed on a Caad9 is a cardinal sin, but for my ride its fine... no real hills and its freewheel, but yeah, avg cadence is 90-100 and i go about 25-26, but when the energy is in and I don't have wind pushing against my body... a solid 30-31 for a few miles, but then my heart rate jumps to 180+

I did the conversion because I found out for 3 months I not once changed my gears. I figured if my drive-train was to go unused then I might as well protect them from the elements completely and retain their resale value.
