I'm 5'10 and ride a small socom. Like the other guys who mentioned that they ride bikes small relative to their height, I like the tight feel. But I still only have about an inch or 2 between the lowest part of the top tube and my crown jewels. I think most smalls will be to tall for you in terms of standover height. Just keep looking around and checking the geometry info on company websites, their must be something with a very low standover. The small sx trail has a really bent t.tube but I'm not sure if that's because it's really low or not? Just research. See what will fit best.
thanks man but im looking at a norco and a bottle rocket and i just wanna no if its gonna be like overly huge or just a little bit cuz i have a 15" hardtail and i ride it so yea
