Measuring Wheel Size

Set wheel size

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

25-559

23-571

35-559

37-622

47-559

20-622

52-559

23-622

25-622

28-622

32-622

42-622

47-622

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 training computer.
