Also, Sugino knurled chainring bolts are probably less expensive than Dura Ace. I've used them as replacements for Dura Ace when I happen to break them.

I've ordered from there before. Nice people.
The lobed inserts are clever, I guess maybe they're patented by Look? That would explain why you don't see them anywhere else.
I've heard there's good reason not to machine a forged part from a structural standpoint, maybe that's why they don't bother shortening them.
