The Sugino XD 600 (46,36,26) worked well for us, but we eventually replaced the 26 with a 24. I rode coast to coast with the 26 and it was fine. A few places in the Appalachians I would have used the 24 if I had it. The 26 was completely adequate (for me at least) for the TA in the Rockies. My companions had and used the 24 in both the Rockies as well as in the Ozarks and the Appalachians.
Edit: I personally would pick the Sugino with the aluminum rings over the one with steel rings
