No argument here...
2nd time around, mine is dialed in. NOT as much mileage as you...
The basic design, (not-with-standing the quality of materials), is a crude method of transferring power in a high-speed mechanism to cause wear, (catastrophically so), to a critical structural element: the spokes of the wheel, where they intersect the 9 mounting bolts.
As the rubber of the clamping mechanism fatigues and degrades from time and use, there will be continuous maintenance keeping the sprocket aligned laterally.
There is also the situation with the eccentric run-out and no metal spacer to physically hold the assembly in a firm, concentric position.
As I said, there's no argument.
It's all in the engineering.
I'll look forward to reviewing the thread you mentioned, 2door!
