Yes, it's a High School math test 
Actually I want to know what type of bikes you like riding. I've been trying to get my wife more interested in trail riding and her current bike isn't doing it. First, it's too big, IMO. She's 5'11 and the top tube is 19'' which I think is too long but that's what she was fitted with at Bike Line a good 8 years ago.
Anyway, I have the parts to build something up for her but I wanted to know if there were any frames out there that are really comfortable for women. I know there are WSD frames but I wanted to get a handle on whether or not most women like them or if any type frame, given the right size fit, works.
Looking at a hardtail and I would think a 17 incher.
