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.
