i disagree. i am 5.5 was 5.3 when i bought a small frame, and i regret it now, i think a medium would be good because you can also grow into it, ive had mine one season and its to small.
just under 30 I believe, once I have it back together I'll weight it and inbox you, finished painting my rim's, so I just have to put em back on, and I'll post a picture later tonight.
