Great photo of the Nomad, all hidden away in a suitcase Mickeg. Makes the appeal of S&S couplings that much greater.
Saved me a lot of money for air fare by not having an oversize bike box. I think it was about $300 USD in savings for that trip. But the cost (in addition to the purchase price of the higher cost frame) also included about $250 USD for the case and a couple hours in each direction for disassembly/packing and unpacking/re-assembly.
Savings are highly dependent on which airline you use and how much you can save.
I built up the bike so I am comfortable with the mechanical aspects of it, but those that are less mechanically inclined might not be as interested. When you are even taking the water bottle cages off the frame, fork out of the frame, etc., it could be less appealing to some.
The Nomad is a heavy bike, that with the weight of the case and you are close to the weight limit. I had a few bike parts in the green bag. The rear rack (Tubus Logo) did not fit in the case with the Nomad, that was also in the green bag.
A big advantage of avoiding the oversize box is that I can take a taxi to and from the airport. Taxis in my community do not have the capability to haul a bike box sized box, thus I would have to rely on the very few friends that have a large enough vehicle to ferry me to and from an airport. The ease of getting to and from an airport without a bike box I am concluding can be almost as important as the lower air fare cost.
And if you have a coupled bike but you travel with someone that does not, you still may have the difficulties of worrying about how to get to and from an airport when one of you can't use a normal taxi. My last trip, I traveled with someone that does not have a coupled bike. We ended up driving several days to and from the starting point instead of flying, in part because his bike is not coupled.
