That's not necessarily a bad thing. Sizes are somewhat flexible. My favorite bike is 58cm, technically slightly large for me (I'm 5'11", 33" inseam). I can straddle it flat footed but there ain't much room for Johnson and the twins. But with 175 cranks, a longer top tube, etc., it's like riding a sofa bike. I can ride it all day and night without getting tired. I suppose it would be closer to a French Fit if I used drop bars, which I might someday as my neck conditioning improves.

My new-to-me (going on three weeks and about 15 rides) road bike is a 22.5" 1989 vintage Centurion Ironman. Technically 57cm, although Centurion had no such official size in the catalog so it was probably rounded down to 56cm or up to 58cm. But it's very noticeably shorter than my 58cm Univega. It has 172.5 cranks, shorter top tube, steeper head tube angle, very "sporty" ride that translates into more neck pain. Took about three weeks to finish some 10-20 mile rides without stopping for a minute to stretch my back and neck.
