Are you sure about 56cm? That might be a bit small for many of your height. FWIW, I’m a very leggy 6’0 and ride 63cm frames. Bigger frames, especially with horizontal top tubes, make it easier to get the bars close to level with them saddle, which you’ll appreciate on the kind of trips you’ve mentioned.
