Did I say I had a flat tire after yesterday's ride? Make that TWO flat tires.

The front seems to have a damaged stem. It's very short and has been a problem since day 1 because I have trouble attaching it to the floor pump. So no surprise that it's now shot.

The rear tire has a puncture. Upon inspection, I'm finding many cuts in this tire, some pretty deep. There are no holes going all the way through but that doesn't seem to matter. But the kicker is, after replacing the tube and filling it with air, there is the beginning of a split on the side. This might have been caused by the tire hitting the hallway wall as I carry the bike up and down the stairs of my apartment building. Not that it matters, though. Because it's time to get rid of these Conti Grand Prix tires and get some new Gatorskins.

Should I get folding bead or regular? What's the difference?
