Can you measure the inside diameter of the race. That will give you the maximum size of the tool.
13mm = 0.512". If you could find a 1/2" Allen wrench, that would give you an idea of how close you will be with the 13mm.
A metric bolt with a 13mm head would also give you something to test. Even a bolt with a 1/2" head will tell you if you are close.
Because of the way those are designed with the 12 point, I would choose a wrench that fits tight.
Whew, it looks like finding a 13mm Allen Wrench will be a pain. A few that might work coming from Europe.
Back to trying 1/2"?
I never though about that. I may try it although I think a 13mm will fit perfectly. There's no where in my area that has these size keys. The biggest they got is 10mm. Therefore I have to keep ordering and sending back these packages until I find the right one. So time consuming.
