OK, assuming I fit my old Pinarello steel roadie which is a 56cm c/t and 55.5cm c/c top tube and stand over of 31.5inches, traditional Italian steel road racer and am 5-10.5 and PBH of 86cm and a fairly normal mesomorph (arms proportional to legs) build, would I go with a 54 or a 56 in a Surly Cross Check? I do not intend to race the bike but to use it as a multi-purpose, dirt road, light trail, multi-surface and road bike. I intend to fit smooth center type tires and fenders for winter and even commute with it as well general fitness riding.
I live down a dirt road I have to traverse before reaching pavement, my old Pinarello and Guerciotti (56c/c, says 57cm) do not like it one bit.
The Surly and the Soma DC and all of these bikes seem to have long top tubes and this is confusing me.
Thanks for any insight.
