Here's a pic, this is from the same roll. Is there a difference in early or late UG?
(The other gold UG chain is earlier, as its most likely from the 600 EX Arabesque group).
I don't have that here, that's with the bike out back in the shop.

(Also, if it matters, the axle is set to the most rearward point in the dropouts, which are forged with screws. I did that to gain as much tire clearance as possible between the tire and seat tube. As it is, I have to deflate the tire to get the wheel out, as well as to gain some derailleur to freewheel clearance. It was close with the wheel in the middle or the dropout, but since I also swapped up to 28mm tires, I needed the added space). It was close but never hit in any position, but it's more normal looking now. Since it shifts gears fine and my only issue is noise, I don't think that gap is the problem.
