I just sold a 56cm semi compact goemetry frame that was a hair too tall for me but I liked the length so now I am on a 54cm with a 120mm stem and it is just right . I am 5-9 with a 31 inseam. I you are 6 ft it is way too small for you . You would probably need a stem that is not avilalable, I may be wrong but I think they only go to 130mm.
