Do you intend on using flat bars for single track or always use drop bars?
I considered a Fargo, but wanted to use flat bars... I did a CAD layout of my current mountain bike and compared it to the Fargo geometry and determined that the frame geometry for a drop bar frame does not lend itself to a decent setup for flat bars. I think I had the same result with the Long Haul Trucker (26" wheel). I'll take a look and see what size Fargo I drew up.
I'm not wise enough to understand why a single handlebar position isn't good enough for all intended uses.... what has me perplexed is why the ST location would be lower than the road position.... but it is a personal preference, so it is what it is
