Hello List Friends,

I have three NOS Mavic Mod E rims that have no size markings on them. Can anyone advise what/where to measure (please be very specific) and the dimensions I should look for for in order to determine if they are 650b or 26"? They are not 700c just based on size comparison to numerous other 700c rims I have in my stash.

Thanks in advance,
