Well as I see it, that's exactly the benefit of disc brakes. You can achieve the exact same overall diameter using any two distinct, given rim sizes, just by varying tire casing sizes. That's why fat 650b conversions work on frames that originally ran skinny 700c. Another cool recent development and example (this week, in fact) was the announcement by V-Rubber that they will be releasing a 650b tire called the "trax fatty," which will be about 3" wide and roughly the same diameter as a 2.1" 29er tire which is, in turn, about the same diameter as a 26" x 4.5" tire. This means that I'll be able to run all three on my fat bike (the bike I ride more than any other).... *without* changing the geometry!!! The Atlantis is specifically sold as being versatile enough to take a skinny road tire or a fat mountain bike tire - but in entirely different diameters! I could sort of see where Riv could eventually embrace the idea of a bike that had this versatility, but by varying tire width alone, rather than by varying width WITH diameter as happens now. (Of course I say this as someone who still prefers cantis and who doesn't really expect it to happen either. Fun to think about, though....) -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
