linked to the bike appear under the bike name.
You'll find the following settings:
BIKE NAME: Bike 1, Bike 2, Bike 3 or Bike 4.
WHEELSIZE (MM):Set the wheel size in millimeters. For more information, see Measuring the wheel size.
SENSORS:View all the sensors you have linked to the bike.
MEASURING THE WHEEL SIZE
Wheel size settings are a prerequisite for accurate cycling information. There are two ways to determine the
wheel size of your bike:
Method 1
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 the
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 when the valve is at the starting point to mark a full rotation. Meas-
ure the distance between the two lines.
Subtract 4 mm from the distance to account for your weight on the bike to get your wheel circumference. Enter
this value in the cycling computer.
Method 2
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.
You can also check the wheel size from the manufacturer.
