5.2 Setting and measuring the wheel size

You must set the wheel size (wheel roll circum-
ference) of your bike so that your VDO computer
can measure correctly. There are 2 ways of
doing this:
5.2.1 Setting using tyre table
The common types of tyres are listed in the tyre
table. If your tyre type is not listed, we recommend
entering the wheel size manually.
The values given in the table are approximate
values. These values differ according to brand, tyre
height and tyre profile. This can consequently also
lead to discrepancies in the distance measured
and the speed shown.
