The geometry of this frame is most different in the larger sizes, where the STA would usually be more slack. A seatpost with a lot of setback might be needed. The 74 degree angle is a bit steep, even in the medium size. A lot of smallest size frames have a 75 degree STA, which is steeper than I'd want, but I could use with a 32mm seatpost setback. I bought 32mm setback posts for my Cinelli Superstar frames, but it turned out that the STA was not the 75 degree listed on the geometry chart.
I ride an XS size in the Superstar, but most brands sell one size smaller. I've never bought the smallest size in other brand. My Yoeleo frames are a 47, which is the next to smallest. My LOOK 585s were size S, the next to smallest.
