I'm new to dirt jumping and want something cheap and 24" ish. I've got my eye on a bunch of used bikes, including a specialized p1 from 2006. This is the one that came stock with 26/24" wheels. My question is, do these bikes ride like crap with dual 24"s? I don't want the combo, I can tell you that right now, but it sounds like a decent deal for 400$ brand new....
