Your height, inseam and arm lengths don't figure into the equation? You didn't mention them... Are we supposed to be mind readers???

These new bike frames - fugetaboutit.

When I bought my Mk V, I straddled the bike and made sure I could clear the top tube standing flat. Actually since it was special ordered I used a couple other bikes of the same geometry for sizing. When it arrived, I adjusted the height of the saddle and bars to my arm lengths, and that was that. Strange how it still fits after 39 years.
