I'm looking for a loaded tourer right now and I was surprised to see that the "58cm" Soma Saga had almost identical stand-over height and seat tube length as my 55cm Miyata 914, but a few cm longer top-tube, seemingly throwing off what I thought might be a good fit. I would think you'd want a short top tube to give a more comfortable, upright, riding position for touring. What am I missing here?
