The Flyer has pretty stiff springs, it has to work for everyone, from 80 - 250 or more pounds. So the lighter you are the less effect you will get. I weigh a little over 200lbs and the springs work great absorbing all kinds of road shock. I think if I weighed 150 lbs, the saddle would be less effective, still work for the big bumps, but not the small stuff.

Hope that helps.
