I have a CC-RD300W and I am putting new tyres on the bike 700x37C but this size tyre does not show on the manual for the wheel circumference.
how do i find this out for a true reading on the computer

    If you look on page 1 below the tyre circumference table it shows you the method for custom measuring the circumference of a wheel and tyre combination that is not listed in the standard table. Input the 4 figure distance measurement, in mm's, into the computer at step 3 Preparing the computer.
