I reckon you may want something more like a mountain bike crankset also. My setup is 22/32/42 at the front with a 8-Speed 11-30 set on the back. Before I went on tour I very rarely used the small ring at the front but on the tour I think I must have spent half of my time on it. I did tour some of mountainous area's of Austria though. I am not up with the brands however so can't recommend a specific model. (I have Shimano Alivio gear) Best of luck with your trip.
