Hi Sam,
The photo is you posted looks like one of the earlier model Clem Hs (maybe a 2017 or so).
Bikeinsights.com will give you geo info.
Sizing, like Jim says, isn't just about height but pbh, riding preferences, and so on...
That being said, I'm 168cm tall and found the 2019 Clem H pretty perfect, but I used bullmoose bars. I did not like it (too scrunched up) with swept back bars (like the boscomoose in the photo).
Cheers,
John
