Not a Pro by any means but there are plenty of time trials in which 25 -27 miles an hour do well and place when the course is not flat. You are right in one thing, I love to ride and I love to compete against myself and others. As a personal trainer, my motto is the body will only go where the mind will take it.. I will get better as a rider, just curious about the disks. I know an areo helmet increased my speed by almost two miles an hour and the geometry of the tt bike (kestrel air foil) also increased my speed over the trek y foil road bike that I ride.
