if you calculate it based on the circumference and rounding the number it would be

(26inch) 590 / 3.14 diameter = 187mm

(24inch) 540 / 3.14 diameter = 171mm

Or using the online calculator https://www.omnicalculator.com/math/circumference

Anyway I need to know because I'm ordering a new chair and need to adjust my front frame and rear frame heights based on the difference in height of the wheels.

A difference in height of 16mm seems too small from what I can remember when seeing both sizes together but I could be wrong.

If anyone knows let me know?

Thanks,

Rob
