These bikes were likely 7 pounds heavier than today's winners and less aero.

Anyway, we have to figure out how they are losing 5mph to today's fast flat crits. I think the weight matters a lot, as does the aerodynamics and ...these are fighting words, but I also don't think the fitness was near what it is now.

Can't forget tires. I still remember feeling a very noticeable difference going from the stock tires (some lower end Vittorias, Rubino maybe?) on my first road bike to GP4000s.
