Measure Wheel Size

Wheel size settings are a prerequisite for accurate cycling information.

To set the wheel size, go to Settings > Bike SET. Select Bike 1/ 2 / 3 > Wheel SET.

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. Measure 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 ETRTO chart on the following page. Wheel sizes on the chart are advisory as wheel size depends on the wheel type and air pressure. Due to the variation of the measurements, Polar cannot be held responsible for their validity.

You can also check the wheel size from the manufacturer.
