Calculating the K-value

K = 10 x number of revolutions of the clamp cable / tire circumference in cm.

You can determine the number of revolutions of the clamp cable in this way: disconnect the clamp cable from the odometer. Put a paper clip on the square inner cable and rotate the wheel exactly 10 times (note on the tire).

In the meantime, count the number of revolutions the paperclip/km.meter cable makes.
For example: 10 x 27.5 revolutions / 202 cm = 275 / 202 = 1.36 is rounded off 1.4
