There are 2 standard sizes, red, for a brand new crank and blue for a used non re-ground crank. I got the blue ones, apparently there are 4 more sizes for each time the crank can be re-ground

what size are the blue ones do you know?
Is there a code on them?
I thought they used the different colours for factory process intolerances, mixed and matched them.
