Ok, I should have said "the main reasons". When I look at people riding around town, way too many have their seats too low - much more than people that have it too high. And I rarely see people spinning too much, if they're not ready, they just won't spin as fast. The average person doesn't spin enough. Of course, if you're going downhill on a fg, that's another issue. I was talking about general cyclists.

And from the bikes I see in the SS/FG gallery, I can foresee many sore backs, stiff necks and numb wrists in the years to come That's unless people don't actually use their bikes a lot.
