Wheel Size Setting

It is important to set the correct wheel size to calibrate the display

so that reasonably accurate speed and distance can be shown.

The GRANITE and DIAMOND

models are supplied with 26”

wheels and are set to 26.2/2133

when they leave the factory.

The QUARTZ model is supplied

with a 20” wheel and has been set

to 20.2/1590 prior to leaving the

factory.

If you replace the original tyre with a different size then refer to the table at the

end of this manual for the correct calibration settings. (Page 30)

Alternatively, you can determine the circumference of the tyre by measuring the

distance travelled in one revolution of the tyre on the ground and set the display

to the nearest value available. (measured in mm)

To change the wheel size setting press and hold the SET button for

10 seconds and then use the UP and DOWN buttons to select the

required value. Press the SET button to confirm your choice.
