no, the 19" is XL. These are the sizes, which seem pretty average: 15", 16.5", 17.5", 19". I guess Giant chose to picture the biggest frame maybe. I remember when Kona did this and it made the bikes look very strange in print.xy9ine said:ya, but giant has always gone overboard with seat-tube lengths on their dh frames. they could easily lop a couple inches off & provide adequate seat extension. these ARE dh frames, after all. the large frame looks positively xc; what is it, 19"?
