    Electronic speedo - wheel size

    I'm running 120-70-17. Calculated the wheel circumference for the speedo at 1852mm.

    Anyone else got one? I want to compare notes. Ultimately I guess I'll connect up my GPS to compare it.

      Ok that's something to think about.... I did a pi x dia calculation then marked out the floor to come up with the 1852 & got the same answer either way.

      Can't imagine you have a larger profile tyre than my 70 so maybe it's down to the profile of the riding surface of the tyre.

      Thanks for the info.... Maybe someone else will chime in soon
