read today that due to wheel size a 29" in the 24x36 position (granny) is equivalent to a 26" in 24x28 (roughly 3rd from highest in back). the article also stated that the 29er in other equivalent gears is 15 % faster than a 26" at the same rpm. this would explain alot when it comes to my riding vs my friends on 26ers e.g. equal to slower on +15% grade climbs and much faster than most as the grade decreases.
