Can't - doesn't have the mounting holes.

I went to look at it again today. The discounted model is a WSD, that is "Women's Specific Design". In and of itself that doesn't bother me, but I do notice that the frame is sort of squashed down when compared to the standard 7.3; is this an inherently bad thing?

More bothersome is that they only have two sizes left - 15 and 17.5 - and I'm afraid the bigger of those might still be too small for me. How exactly do I figure out which size is good? I'm 180cm (5.9 feet according to Google) and fairly slim.

BTW, it has a Shimano Deore rear derailer and Avid Single Digit V-brakes.
