I really don't long arms or a long torso. I am pretty much average, just rounder than most women.

I relied on the the bike shop person to tell me what size. I probably should go back and look at a small. I just assumed that I was given that size due to my weight. One of the shops kept saying I was right on the borderline. I guess between small and medium.

thanks for the information. I'll go back to the different shops and see what they have and try to ride them.
