Well said Glass, nothing further needs to be said on this matter.  So to just call out the actual difference between the wheel sizes and the BS that manufacturers have and are still trying to make you believe. So looking at the very simple math, you can easily see just how much BS that actually is, if 650B was exactly between 26" and 29", it would have an ERD of 590.5, i.e. it is just over 1/3 bigger than 26", or more accurately 2/5 bigger. 622         584         622                              63             63            63 584 -       559 -       559 -                            2 /              3 /            5 / -------       ------        -------                          ------            -----           -----    38           25            63                           31.5             21           12.5  x 2 = 25
