I averaged about 150/week last year on my hybrid and went the road bike route early this year. I did a metric century last year with no problems and actually comfort on my hybrid is no problem at all. My Bianchi hybrid was oriented to road work, it had 28mm Continental Gator tires and a similar riding position to my road bike. I find that I'm about 2 and a fraction mph faster ride average day in, day out on the road bike. At least some of that is due to the superior gearing, it has 10 speed 12-25 and the shifts are so closely spaced that it is a big help on keeping me in my powerband.
I'm 63.
