GB
You may enter two different wheelsizes into your VDO CYTEC C 15, i.e. one wheelsize for your street bike and another one
C
for your mountain bike.

Your VDO CYTEC identifies different wheelsizes as WS 1 = wheelsize 1 and WS 2 = wheelsize 2.
following defaults are entered
wheelsize 1 = WS1 = 2155 mm
wheelsize 2 = WS2 = 2000 mm
Watch out: Above defaults are automatically applied after a battery change.
After a battery change, the correct wheelsizes for your bikes have to be re-entered

How is the wheelsize precisely determined?

Place the front wheel of your bike with the valve at the bottom, mark this position with a line and push your bike ahead until
exactly one rotation of the front wheel is completed. Draw another line where the valve now is. Take a ruler and measure the
distance between marks 1 and 2 which reflects the wheelsize = wheel-circumference. The figure measured (inches or mm)
is the wheelsize to be entered into your computer.
