• To teach a new sensor, make sure that there are no other cadence sensors nearby (40 m/131 ft) and then
select Yes.
After selecting Yes, Start test drive is displayed. Rotate the crank a few times to activate the sensor.
The flashing red light indicates that the sensor is activated. Completed is displayed after the teaching has
been finished. The training computer is now ready to receive cadence data.
To return to time mode, press and hold the STOP button.
Measuring Wheel Size
Select Settings > Features > Shoes/bikes > Bike 1/2/3 > Wheel
Wheel size settings are a prerequisite for correct cycling information. There are two ways of determining
the wheel size of your bike:
Method 1
Look for the diameter in inches or in ETRTO printed on the wheel. Match it to the wheel size in
millimeters in the right column of the chart.
ETRTO Wheel size diameter (inches) Wheel size setting (mm)
25-559 26 x 1.0 1884
23-571 650 x 23C 1909
35-559 26 x 1.50 1947
37-622 700 x 35C 1958
47-559 26 x 1.95 2022
20-622 700 x 20C 2051
52-559 26 x 2.0 2054
23-622 700 x 23C 2070
25-622 700 x 25C 2080
28-622 700 x 28 2101
32-622 700 x 32C 2126
42-622 700 x 40C 2189
47-622 700 x 47C 2220
Wheel sizes on the chart are advisory as wheel size depends on the wheel type and air pressure.
Method 2
Measure the wheel manually for the most accurate result.
Use the valve to mark the point where the wheel touches the ground. Draw a line on the ground to mark
that point. Move your bike forward on a flat surface for one complete rotation. The tire should be
perpendicular to the ground. Draw another line on the ground at the valve to mark a full rotation. Measure
the distance between the two lines.
Subtract 4 mm to account for your weight on the bike to get your wheel circumference. Enter this value in
the cycling computer.
