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.
I go back to my original post that a lead weighted bat will quicken my bat speed. Did you ever see a major league batter in the on deck circle without the doughnut on his bat? A SS/FG will make you work harder than a geared bike and therefore is a good training technique. It sounds logical to me....but I could be wrong.
