My Sam is recent, purchased in May. Blue 51. The geo chart for my Sam gives 53 as the space between chainstay crimps. With Surly Knards, I see at least 3-4mm on either side, maybe more.
The Maxxis Pace supposedly* fits a bit smaller than listed width, at least on something like my 19mm inner-width rims. My goal is to find the perfect summer trail tire. I can do about 20 miles, mostly dirt and gravel roads, to a network of about 30 miles of fantastic singletrack around Whitefish, MT, as well as some nearby sections of the Great Divide, but I'don't like to have thebiggest tires I can for it. *This is, of course, iffy speculation -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
