I know I'm supposed to consult the fit calculator, but my results were inconclusive.
I'm buying a Surly Steamroller, and I'm not sure if I should go with the 53 (54.7tt) or the 56 (56.8tt). I'm 5'9-10 and have an inseam of around 31.5. I'm currently on a 56 Windsor the Hour which has a 53 seat tube with a handful of seat post showing. The 56tt feels okay, but I'm worried that the longer top tube of the Steamroller will be too long. At the same time I'm worried that the 54.7 will be too short. I do like the feel of smaller bikes, but I'm not sure if the 54.7tt will be too small.
If it matters I will mostly be riding with zero-drop bullhorns.
