I built up a Carbon Fiber wonder bike this year. So far, I am still getting used to the bike and the compact double 50t 34t gearing and with the crappy weather, I am way behind on miles over last year. I will say that the bike is not as stiff feeling as I thought it would be. I am still out of shape but getting my legs back slowly. The CF bike still managed to give me a personal best on one Strava segment , and two second bests on a couple others. I will know more by the end of the season.
I do hope to give a person on a steel ride, who is in far better shape than I, a great day and bragging rights for passing me on my carbon fiber wonder bike. I do not get passed very often on any of my bikes, but when I do, they are really fast and fit riders.
