Here is a follow up. I got titanium chainplates - really cool stuff!
My shackle pin seems slightly less than 0.5" and AT made a hole slightly larger (0.520") to account for tolerance, etc., so in the end, there is almost a millimeter of free play.
Is there any shock load to worry about or it's too small? Do you think there is a way to calculate it?
Thanks,
Gleb
