5 7 ish I think but 31inch leg. Use a thomson straight, no where near full extension, but granted looks quite high due to the drop on the 16. The 2011 frame has bigged seat tube which might help that, just waiting for mine back as cracked my ’09 so have got a 2011 coming under crash replacement. Has standard thomson stem that comes with a pro. No problems and very comfy to ride! You just need to go sit on a couple and make your mind up, the extra couple of inches in your height could be the difference between a 17/18 and short/long stem 🙂
