Ok so I’ve now tested size on a med patrol which has the same geo as the scout.
And it felt almost identical to my blur.
Considering the bike had a 60mm stem (so I could shorten it anyjow if really needed)
I’m 100% (sorry helpful) that the small would be to short for me.
Glad I had oppertunity to test though, numbers don’t always show you the way.
Many thanks to the guys at tamed earth bikes for their help, really nice shop with very knowledgeable staff.
