Rim size means nothing, the Ape and Boss have a 0.1cm difference in rim thickness
Ape 21.1 1.5 1.2 16.2 2.4 5.7
Boss 21.2 1.5 1.2 16.2 2.5 5.7
Both are speed 13 on the Innova scale, but these discs are nothing alike.
If you mean rim size means everything, then you are right. I don't think you are thinking this through at all. You are coming up with your own "speed" which is fine, but not what we talk about here or what the manufacturers use.
