After my first metric century the other day, I've begun doing some thinking about my next bike. I have two questions:
1. Is there some kind of rule of thumb that would compare riding a knobby-tired low-end MTB on the street with a better bike equipped with thinner tires? In other words, I went a particular distance (in this case, 62 miles) on my Trek 3900. Had I been on, for instance, a Trek 7500 FX (or something similar) would it be reasonable to expect that I could have gone 10% further on the same effort? 20%? More? (In other words, would a better bike -- more appropriate bike -- make a Century more feasible?)
2. My next bike will probably be a sub-$1000 hybrid (I like flatbars). Probably can't buy until Spring unless the deals are just completely irresistable. I know there's a ton of threads on this in the forum, but I'm asking particularly from the 50+ group -- any suggestions, recommendations, etc. as to which bike?
