Anyone know the brand of this chainring?

The outer ring made in the US. Stolen picture from a for sale thread.

Thanks!

I'd guess "Vuelta."

Ditto on Vuelta. They made many different size and color chainrings in the early ‘90’s.

This makes sense. I didn’t realize Vuelta made them in the US?

However, when I searched, couldn’t find any rings with that scalloped out section.

I am pretty sure that ring is from a company called QBP. I have one, 110bcd-46t. I purchased it from EBay. If you look closely at the outer edge, below the teeth, you may find the info in very small etching. The ring in this picture, the info is at about 5 o'clock

I have owned a few Vuelta rings, they have all had a Vuelta label

I can't get a clear shot of the etching

99% sure that QBP (Quality Bicycle Products) was/is just the distributor and Vuelta is the manufacturer of this "Engagement Ring" (clever branding, huh?)
Vuelta still make some similar flat (no pins or ramps) rings in the USA but I believe this (the OP's) model has been discontinued.

That is it! Thank you. They seem to be nice rings!

Nice basic ring that I used with a friction shifting set up. 7075 aluminum, light and durable. I removed it only because I acquired a ring that is closer to matching up with the crank.

The triplizer ring underneath in the OP pic is a Mikkelsen. I goes on a 144 mm double crank and gives you 6 holes to mount a TA Cyclotouriste granny ring.
Those are rare and wonderful things, as opposed to the Vuelta which is a commodity item, good quality but commonplace.

The Mikkelsen design dates back to before the invention of the 74 mm 5-bolt bolt pattern, which originally came on Sugino Aero-Tour or AT cranks. Before the debut of the AT, there weren't so many good choices for the granny on a triplizer. Bernie could have used the Stronglight 99, but that only went down to 28t, vs. 26t for the TA, plus the TA had better selection and distribution.

Here's the Engagement Ring in original packaging. Doesn't have the engraving in the web like the one shown in the first post so maybe that one was sold by Vuelta as some have said.

Those are what I’ve got! Thanks Bob!

Someone on eBay had an auction for one last night and the bid was like $17 or so when I saw it.

Edit: it was a Merz. Ended at $33 without shipping.

From their catalog:

The Merz is super cool and rare too, $33 is a steal. The Merz only fit rings with a 100 mm BCD, which back in the '70s was limited to only one size, 36t, until Jim made his in 32t and 31t.
In modern times, a few people (myself included) have made 100 mm rings in 30t, and I made one in 29t.

With the baby boomers aging out of racing gears, there's an increasing pressure to convert '70s full-Campy racing bikes to lower gears, and this (or the Mikkelsen) is the OG way.

Well, another time-tested way BITD was to drill the 5 spider arms at a suitable BCD for some small granny, be it 74 mm (Sugino AT), 86 mm (Stronglight 99) or 100 mm (Campy Record triple). There were even a few others like Tevano, Gipiemme and Assos that had their own wacky bolt circles — avoid those unless you have a stack of chainrings to fit.
With the drilled spider method, you don't use a triplizer middle ring, but you need some sort of stand-offs or spacers to hold the granny the right distance away from the spider.

That was a steal, even without one of Jim's small rings. I guess I need to keep better watch for this sort of thing. A lot of these I see are worn out including the one I have. It seems like they might be a challenge to adjust shifting on for some maybe especially for downshift under load. Mines too worn to adjust well so I didn't keep it on, It was too hard to shift well when it mattered.

The ring is a "Salsa" branded version. Distributed by QBP, yes. Made by Vuelta? I don't know.

Oh crud, I didn’t even see that in the lower left corner. Great catch!

Now I see the Salsa. My brain was looking by for small etching like on the one I posted. Pretty obvious when one knows it's there.
Good eyes.

It stuck out like a sore thumb to me because the one in my image is my own. :lol:

Probably my most used track chainring over the past 5 years. I hold it, as well as the other QBP Engagement Rings I've owned, in high regard! It's often my first search on eBay when I'm looking for something without ramps and pins.
