Was out on my "road" bike the other day on a group ride with some young brisk riders and ended up with just me and the leader together up front. Kept up OK but had to work a little harder than he was I am sure. But I think I had a specific handicap and it wasn't my platform pedals. I don't think that much of it can be attributed to lack of tight aerodynamic clothing, not bike weight because my bike is CF and in any case the syndrome was this: on a long downhill, my new roadie friend is coasting and pulling away from me whilst I pedal. I have flat bars but was hunkered down. He was in the hoods so our postures were similar. Of course, he is running 23s. I am running 28s which are so much more forgiving of road hazards and chip seal, etc., but it is my thought they hurt me in this particular case.
I do all my own work and can assure you my brakes do not rub. I can't see type of hub bearings making this much difference. The man was bigger and heavier than I am, but, being bigger, should have presented more aerodynamic resistance in proportion to his weight.
Tires are some kind of Bontrager 28s with Spin Skins and were inflated 110 frt, 120 rear.
I guess I will just have to get on EBay or AliBaba and order another CF frame, fork and etc. from China and build my #8 bike to leave permanently set up with 23s.
Or maybe shave my legs?
