This came up last year as well. Everyone just took a quick look at the shaft with a pair of calipers and assumed it to be 5/8ths. Then we all had to figure out why we couldn't get any sprockets to go on.

I think most teams just ream out the sprockets, and call it even. It's a pain, but hopefully teams learned a lesson and took the time to look at the drawings this year.

Thanks for the reminder though, I had completely forgotten.
