Good points - sorta like a design to failure point to keep more expensive item from breaking.
In this case I got this November-2015, I checked the bolt for snugness and it was "good", I never added more torque to it.
The chain had some "extra" slack in it a few weeks back, I adjusted that to have 1/2" slack.
Since my order is in, should I change the bolt grade to a SAE 3 instead?
I'm not sure how much true engineering was done to this design, vs copy another and use best practices.
[edit] too late, the order was just shipped - they are too fast!
