Hi all,

I want to order a new set of roundels for Blanca. (yes, she has a name, yes she is black, and yes... I know what Blanca means, that the joke.)

I measured her roundels front and back but I'm not coming up with the standard 82mm I thought I would.

The rear measured 3.25in which comes out to 82.5mm (using standard 2.54cm per inch). This I'm figuring is a standard 82.

And the front measured 2.75in... which comes out to a more confusing 69.8mm
Is there a 70mm? or a 69mm?

Or are my measurements off?

Thanks all...
