I've been thinking about getting a new hardtail bike. Im interested in buying something so that i can go on the rides with my local bike club, and still be able to go hang out with friends and do some of the jumps they like to do. I was sorta thinkin about getting a specialized hardrock or somethin like that, but i can only spend around 400 bucks, so i suppose i have to buy it used. anybody got any suggestions? thanx!
