Yes, I am in BFE.

As luck would have it, I'm just about your size and proportions. I'm just a hair under 6' with a 34 inseam. I have a 58 cm LHT and as many said the TT's are on the long side. I believe that for the 58 cm frame it is in the neighborhood of 586 mm. The 60 cm frame would have a 600 mm effective TT. This sounds like it might be quite a stretch for you. I know it would be for me. I have wondered if a 56 cm fame might have been a little better fit. Depending where I measure to, I only have about 70 mm of seat post showing. Another 20 mm would not make much difference there, but the 16 mm shorter TT might have helped.

I did not cut the steerer tube right away. This allowed me to dial in the bar height. I have the bar level with the saddle which tends to shorten the distance between saddle and bars. Actually I still have not cut the steerer tube, and like some of the other folks have spacers above my stem. I also built this one up from the frame.



I'm OK with the LHT. I put a 70 mm stem on it and it seems to be set up reasonably efficient and comfortable. I've got about 6,000 miles on it with no real issues. But if I could find something with a shorter top tube I'd be tempted to switch.
That's helpful info. Going over what you've just stated and my own personal stats, I'm sure the only reasonable SDT size for me would be 56.

Given your longer legs and shorter torso, I think your fit on a Disc Trucker will end up being a compromise. It wouldn't be a bad idea to find some bikes locally that have similar geometry. Perhaps another brand of touring bike or a cyclocross bike? If you can't do that, then I'd suggest ordering the frame from a shop with a very liberal return policy.
I agree, any trucker will be a compromise. The Jamis geometry fits me a lot better, but it's not quite the tourer that the SDT is. However, the wife and I are considering trailers, which is a whole other thread I'm starting. Point being, the Jamis would work for a trailer just fine and the SDT would be obviously better for panniers.

This works out pretty good on a SLHT/SDT - the longer HT is helpful, and no one will think it odd to see a touring bike with the handlebar 2-8cm higher than the saddle. You can either go short, low angle stem with lots of steerer tube+spacers, or a longer, steep angled stem and much shorter steerer - or any combination in between.

I have a 56 SDT with a 57cm ETT. With my 83cm PBH and other physical dimensions, the CC fit calculator (and others) suggested a 55.5 ST + 54.0 ETT. I currently use a -5d/80mm stem with bar 7cm above saddle to achieve a (recommended) 64cm reach. It's very comfortable, I could go longer.

You can make a fairly wide range of touring frame sizes fit a person with the right stem and handlebar height - not so much with road bikes constrained to typical low handlebar postion. Remember, hbar/reach recedes 1cm for every 3cm of height increase for a 71-72d HTS.

Attached below is a BikeCAD model I made to size my SDT. It's not completely accurate to the specs stated above, as I decided to start with very high bar to delay committing to a steerer length (don't want to buy a second fork). If you like, you can use BikeCAD's free java CAD software to modify my SDT design to your own custom size. You'll need to edit TT, ST & HT length, saddle height, spacers, and stem angle/length. The free version calculates the newer reach/stack for fit calculation, included in my design. The pay version of BikeCAD additionally calculates conventional reach (saddle-hbar), toe overlap, wheelbase, etc. Even designs and prints templates for frame building miters - pretty neat.

I agree that the stem selection these days can give anyone the proper reach within a reasonably sized frame, but the problem IMO is that when you get too upright you start to lose power to the pedals. So if you have no option but to be very upright to have a reasonable reach, you never have the option of getting in better shape/stronger and lowering your handlebars. It will always be too long. Having said that I freely admit I don't know where I am right now in the comfort/power balance. It has been 15 years since I rode 60-100 miles every weekend and have barely touched a bike since. I'm 57 now and that might just affect how low I can go on the handlebars all day, even after I do get in decent shape.

Your post did give me helpful info and more to think about.
