Just because you road bike 'feels' like a rocket doesn't mean you are any faster or powerful than you would have been if you'd stayed riding your road bike.[/QUOTE]

I recently did a tour with some hills. It was amazing to me how effortless the hills seemed. I passed everyone in my sights and wasn't passed. Sure, I guess I wasn't among the most serious of riders but I have to attribute this to my daily workout on my single speed. I have to disagree with you.
