Good intro info. I'm 70+ and still riding some. No centuries any more or anything like that, but trail riding when we have time and energy. You can see my old standby do-everything bike in a thread here:
Trek on trail ...
I will take a bit of an exception to the statement in the intro that mountain bikes (MTB) are not all that good on road. To me, it all depends on the road ... Dirt and gravel roads, they excel. Paved road, maybe not, unless it's rough or has pot holes and pavement breaks/heaves ... I have found that MTB's make good all purpose bikes for local stuff. If I was going to ride a 100 miler (century), I'd opt for a drop bar roadie. But to old to do that now and no real interest. So MTB's work for me with "city" tires for all but a distance/speed road ride. Just my $.02 worth
