FRAME SIZE S/47cm M/50cm L/53cm XL/56cm XXL/59cm
Seatpost-Chainstay Angle 75.5° 74.5° 73.5° 73° 72.7°
This is a really odd geometry measurement. Why are they measuring the angle between the seatpost and chainstay? It should be the angle between the seatpost(seat tube, really) and a horizontal line. Chainstay angles vary and also arent level with the ground.
Also, an XXL frame with only 581mm of stack height is a joke.
