I've been talking to the lbs and also talked to surly (for about 30 minutes) about long haul trucker sizing and haven't come up with the right size yet. I'm right between a 46cm and a 50cm. I'm about 5'6"-5'7"? and my inseam (with pressure) is 31.5 and 29" without (pant size). The 53cm TT on the 50cm frame is pushing the limit for me and I'm afraid the 75* seat angle may not give me enough forward adjustment to get over the pedals. On the 46, I'd have some rearward adjustment if necessary via setback seatpost and saddle adjustment. Is anyone here my size or close to it? What frame do you ride??
