THE METHOD / 01

A clear wayfrom start to finish.

Circumference = π × measured outside diameter.

01

A worked example

A 700 mm measured outer diameter gives about 2199.115 mm circumference.

02

Keep the assumptions clear

700 mm is an example outer diameter, not a claim about the 700C rim standard. A loaded rollout measurement is more useful.
