I was thinking of picking up a pair, since they're nearly on clearance at Nashbar. Anyone have experience with them? Do they last a while? I'd like to put about 2000- 3000 miles on it without worrying about going over a pebble and getting a hole in them. I like that you can really pump them up with a lot of air- that's what I'm looking for! And I'd like a tire with reduced rolling resistance.
