Well I certainly don't doubt the new race bikes can make almost anybody faster 1 or 2 mph faster. I can see CF bikes blow by me anytime, but the big IF is if they show up at all where I go. And it sure as hell is NOT just a fraction of a mph faster. Even 15 years ago I would be going 16 or 17 then a guy comes along at 23. I never in my life did 25 on the flat with any gears. Hell last year a fat guy on a fixie blew by me up a hill. And a young aspiring racer was doing near 20 mph up that same hill.
