PSA- Repro Campagnolo NR chainrings?
I stumbled onto Kopp's Cycle's website today, and saw that they were offering Origin8 Alloy Classic chainrings in 3/32" thickness for road bicycles:
https://www.koppscycle.net/product/o...t-201278-1.htm
With some additional polish, they look like they might pass muster- genuine NOS Campagnolo NR rings in desirable sizes are getting hard to find
and expensive when they do surface.
Anybody here have real world experience with Origin8 products?
Should I buy a 52-42 set and try to make them look good?

I will admit to zero experience with those rings, but, Sugino rings are the same size as campy and co-ops tend to have piles of them.

Those look nice. Probably popular, because many out-of-stock.
I may list some Nuovo and Super NOS or low-mileage ones here.
eBay activity a bit sluggish these days.

I rarely buy anything used, and my local recyclery tends to trash even nice stuff- all just tossed into a plastic tub.
I did recently buy a 52-42 NOS set of SR Royal rings- quite respectable.

If you have NOS NR chainrings in 52 and 42 sizes- post them to the sales sub-forum. SR is too modern for me...

They missed the chance to do 41 tooth versions. I'd be interested in those.

I have yet to hold a 41t in my hands or knowingly see one. I've known they existed since 1977. (Like the fabled 24 tooth fix gear cog but a few years ago I learned that they existed for sale in England and I found a UK fix gear website. I also have a couple of Cinelli 135 stems. Just picked up a Nitto stainless steel 140! And I've been riding a Pearl 14 for a while - actually closer to 155. I've got arms that go forever. Who'd a thunk I'd start collecting and riding hen's teeth.)

Specialities TA makes 144bcd Campy NR replacement chainrings: https://specialites-ta.com/53-double...%5C/5+branches
Per TA: Inner: 41, 42. Outer 48, 50, 52, 53.
Peter White cycles has them, not cheap: https://www.peterwhitecycles.com/tach.php#competition
There may be European sources which have them, too.

I suspect the TA rings will be higher quality than the Origin8 rings, probably made from harder alloy (7075 v 6061?), and thus worth the price difference if you want chainrings which will actually be used instead of just look pretty.

I like the size of the “slots”. Reasonable pricing for fresh cut.
