Ok, OBVIOUSLY the lighter the bike (or any vehicle, for that matter), the easier to accelerate, and the less power it requires to maintain velocity.
Also, the lighter the rider (and assuming equal power capacity) the quicker acceleration and higher top speed capacity.
But we are "clydes." How much does bike weight matter in relation to body weight? I, for instance, weigh 300#, with tree trunks for legs. How much difference woul I really notice between a 30lb bike vs. a 22lb bike?
I know that rotational mass, specifically rims and tires, is the ideal place to cut weight, but are the extra couple of pounds of frame and components all that improtant, especially with people our size?
