13. Selecting the wheelsize
Your VDO CYTEC C 10 WL can work with two different wheelsizes (WS1 or WS2), i.e. one wheelsize for your road bike the
other one for your mountain bike. When using the respective bike you can just switch to the proper wheelsize.
Wheelsize is only selectable if any of the following information is displayed: AVS-RID-STP-MAX
The currently active wheelsize is indicated in the display by WS 1 or WS 2. You can switch from wheelsize 1 (WS 1) to
wheelsize 2 (WS 2) and vice-versa by pressing the MODE 1 button for 5 sec.
14. Entering your wheelsize
You may enter two different wheelsizes into your VDO CYTEC C 10 WL, i.e. one wheelsize for your street bike and another one
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.
