Congratulations! I was in the same situation as you when I ordered my Sam. Had a 14 year old Bontrager Privateer Comp that had been through many reincarnations and it was time to get something new and nice. I think you're going to look back at this as one of the best and most overdue decisions you ever made.
In answer your question about the crankset; I went with the triple because they accidentally shipped it to me (I ordered the double with the guard). After riding it for awhile, I removed the big ring in favor of the guard and I've never looked back. I still wish I got the double to begin with because the gearing would be just a bit more useful. In my case, I bought the 12-36 cassette from Riv and I never quite get to low gear even living in hilly Seattle. The cassette would make more sense with the 42/30 double or whatever it is, for me at least. As for the big Marathons, you can go wicked big if you want. I got some 700x47 ones to try on my Sam and they fit no sweat, even (kinda sorta) with fenders. I usually just ride the 38 version though. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
