#!markdown I have two bikes, a 26er and 650b. I go back and forth between them and yes the 650b rolls a bit better but nothing revolutionary. The difference is a half inch on the radius, fart-all. I think the industry finally revising the old school thinking of geometry has been a huge benefit. For decades a medium bike had a 23″ top tube and nobody challenged that.
