But speaking of tires, I got new ones for the road bike today. The old ones had about 6000 miles on them. I use Gatorskin tires. I don't care if they're a little heavier; I need tough tires. It's amazing how much trash there is, no matter where I ride. If I were into racing, I could still use the heavy tires for training, and switch to something lighter for the actual race.
I also use tire liners; Tuffys, I believe they are. Back in the tricycle days, I got about eight flats in 14 months. I finally decided that tire liners were a wise investment. I can tell you, they're worth it.
