Thompson Piedmont

Thompson has a pretty good deal on a Piedmont gravel bike. It’s a demo bike, size small. Curious about how their sizing runs. My Diverge is a 54, my Aethos a 52, and my Salsa Blackthorn is a size small. I’m about 5,6” so I figure a small will fit me fine. Just curious if anyone rides one and how it sizes out.
