The radius of a 650B wheel fitted with a neo moto

Hi All,

I have been riding 26 & 29ers for a while now but I would like to delve into a 650B wheel size.

Which got me thinking, what is the radius of a average 650 wheel fitted up with a neo moto ???

Having this dimension would be very handy for measuring up potential frame and or forks for my new project and I can I imagine it would be helpful to a whole host of other people who may be considering converting a current or new 26 inch bike/frame.

Any info will be appreciated.
