....need to only lift some of the rider, not all the rider for each bump on the road, resulting in less tire deformation.

According to the old softride website: http://www.softride.com/..._adv/resistance.html



This is actually in line with my results at Ironman Canada, (in 6 years in the 90's my times were similar, but the one year I rode with a softride, my time was 10 minutes faster)....some of that is aerodynamics, but what they say makes some sense.
