Are there more like me? I just don't like anything about road bikes or the riders.
I think most grow out of it eventually.
Maybe it's wanting to compete. Maybe it's wanting to get some kind of riding, any kind of riding, in during the off-season in a part of the country with trails that need to be left alone when wet. Maybe it's a longish commute, and not wanting to chew up the MTB's knobby tires, or swap wheels all the time, or lock it outside. Maybe it's wanting to be able to go out the front door and ride, instead of having to drive somewhere.
Kinda reminds me of skiing vs. snowboarding. Sooner or later, adults tend to try both.
My favorite kind of riding is certainly off-road. But I think my favorite bike is my road bike. Certainly it's the one I've owned the longest. Most of my cycling stuff at this point is lycra and polyester. In general, I probably get a little more ride time on the road, out of convenience, but I'm off-road at least once a week, usually more like twice, and most of my competing is off-road. I miss being in college and being able to get onto some grey trails less than a mile from my dorm, and some really good ones in fifteen or twenty minutes of riding, but life goes on and where I am now, if I didn't also ride road, I'd only be a commuter and weekend warrior.
