i strongly advise against kenda kampaigns. i beleive pyramid continues to distribute these to bike shops, despite their being discontinued. i picked a set up at my LBS when i was short on cash, as they were the least expensive 700x23's they had @ $18 a pop. these things wear rediculously quick, have terrible traction, and are extremely prone to flats. the sidewall in my front tire blew out on a descent.

this is in stark contrast to bontrager selects and irc redstorms, which are great tires around the $15 price point
