If someone can tell me what I'm supposed to learn from that diagram, I'm interested. Seems to me that a typical rear dropout is about 7mm thick. Then add half of whatever stay they have drawn and what they have drawn there is about 10mm on any bike I have ever seen. Plus there needs to be a radius out from the axle to tie all this info together. I guess it doesn't matter too much, because I just cut back the stay until it clears a 13 tooth cog and I'm done.
