A 36 spoke wheel built on a shimano hub is adequate.. and when you happen to bend the rim,
something like it is what you will find at your bike shops along the way..
any thing fancier you are at the mercy of a very busy bike shop that may not have the time
to rebuild a wheel around your high end hub... for several days..
(Staying in a motel and drinking with the locals a couple days aint bad

)
CR 18 is a good rim.. getting a machine built wheel hand checked at the selling bike shop is a good deal , and
if you break a wheel along the ride , that is probably what the bike shop will have, to get you back on the road the same day.
