Hey guys, I'm new here.. and to the mountain biking world.. I've been doing some research lately and I have come up with two bikes that I am interested in. I'm looking around the 400-600 price range. I don't want a Full Suspension and I do mainly XC. I don't want to spend too much money at first, because I want to know if I am going to stick with the sport. So that is why I am looking at these two bikes. I found 04' K2 Zed 3.0 for 430 down from 600 at REI and an 05' Specialized Rockhopper at one of my LBS for 440. Which would you guys personally choose if you had the decision? I know some are biased but I want to hear your opinions anyway.. Thanks..
