I'm 5-9 5-10 and the medium fits about perfect. For me a large frame would be a little large, certainly not as comfortable going down. I would try it first if you can.

 i got the large and it is comfy for me... the only downside is the length of the seatube.... i would ideally have to run the saddle low. with the saddle at a reasonable height sitting on the saddle, i'm on my toes..... not flat footed, but, who rides sitting down with their feet on the ground... the large feels great, will run a shorter stem, right now i have a 60mm i will drop a 40mm on it.

 Good to hear. There is a bit of gray area in the sizing right around your height. It's an awesome bike regardless.

 Indeed it it, will post some pics after ive updated it with newer better parts.... what seatpost are you using?

 It's a KS dropper post, I don't remember the exact model now.

 Thank you. It's been fun so far, nothing like riding a hardtail to keep you game up!
