The  circumference  of  the  wheel  can  be  taken  from  the  chart 
(Pict. G) or be measured by yourself.
Measuring the circumference of the wheel (for a more precise setting):
Put a marking at the front-tire and on the ground (e.g. with chalk). Ride 
straight ahead exactly one turn of a tire (for a very exact measurement, 
check the pressure of the tire before getting on your bike) and mark this 
position on the ground.  Now measure the exact circumference of  the 
wheel between the two markings at the ground (in mm) – see pict. F.

Set with right button, store with left button
