Fleslider and RobbieTunes, thanks again. That pretty much confirms it then. I'm riding a 1989 and loving it. It was that way with my first car, a 1965 Mustang built in 1964. Should have held on to that thing.
The rim information is interesting. I understand, from you guys and the local shop, that these 700x18/19s are really too narrow for the kind of riding I'll be doing. Rough potholed blacktop. I may upgrade to some 23's sooner than I thought. Yesterday we had a break in the rain, so I took a spin around town only to realize the back tire has a bump in it. Can't see it, but can feel it every time the wheel goes around.
I'll put these on the shelf as backup then, but what are your recommendations for new 23's? I read that ratings suggest Continental Grand Prix 4000 S II's and Gators are right up there.
Thanks
