Hmmm . . . I think the WSD-type bikes like the Ruby are made for people with longer legs and shorter torsos - at least that is how I am built and I love my Ruby. I am 5'2" (on a "tall" day) and ride a 48" Ruby with an 80mm stem - interesting to see that nonsmoker3 is 3" taller than me and rides the same size Ruby. Just goes to show you have to get on the bike to see if it fits you . . .
