I have decided to get a Rip Current S, but I am not sure what size to get. I am 57, 5'10" with about a 31 inch inseam from floor to body. The standover height for the L frame is 30.3 and the medium is 29, so either one will work. While I am leaning towards the M frame, the problem is that historically I have always preferred an oversize bike frame (had a huge Schwinn Varsity when I was 14 because my parents thought I would grow into it, but grew to love bigger bikes), but now with age, the speed of this bike and the weight of the bike, I am concerned the bigger bike might not be right. So my question, is a there anyone with similar build to me that has bought either size bike and their thoughts on size.
