Okay, I need some help. I'm starting to get into some urban riding & some dirt jumping. I want to build a DJ/urban bike. I'm 5'6". I'm currently using my trailbike & it feels kind'a big & besides, I'm about to give to the wife so we could ride trails together. For you not so tall riders out there, what's a good size for my height. I'm looking at the Kona (Cowan) & Santa Cruz (Chameleon) frames. Thanks.
