Are Dura-Ace 10 spd chains 3/32" width?

Or narrower?

I have an extra 52t Dura-Ace 7800 10 spd chainring and a NOS 3/32" chain sitting around that I may slap on a fixed gear project.

Would they be compatible with each other?

No. 3/32 is 8 speed.

Congratulations on not reading the first post. Those should work together since you're running one gear.

They should work together. I'm wondering if the narrow chainring will cause any additional drivetrain noise as compared to a 3/32" ring, though. I don't know how new your ring is, but racking up miles on an expensive DA ring designed for smooth shifting vs. buying a cheap no ramp no pin 3/32" ring perfect for a fixie may not make economic sense. Your call, though.

Congratulations on managing to be condescending in all your posts. I also congratulate you on not reading the thread title.

1/8" is even wider, right? Is that a BMX chain?

Yes, BMX or track. No reason to buy a 1/8" chain unless you're running a 1/8" cog & ring.

I am pretty sure all geared chain is technically 3/32". What changes the width is the thickness of the plates and furthermore 10 speed chain has flush rivets.

I remember when Dura-Ace 10 referred to a 10mm chain...

Wow. To clarify things:
3/32" refers to the inner width of chains, as does 1/8". Nearly all geared bikes, up through 9-speed, used 3/32" chains. With the move to 6, 7, 8, and 9 speeds, the outer width of the chain decreased, but the inner width stayed the same.

With the move to 10-speed, the inner width of the chain was finally decreased along with the outer width, requiring narrower teeth on chainrings. A 10-speed chain will still work on chainrings designed for earlier speeds, but it will often get widened by fitting over fatter chainring teeth than it was designed for. (Note that lots of 9-speed chainring teeth are also slightly thinner than earlier chainring teeth and are 9- and 10-speed compatible).

Of course, a wider chain will work fine with a narrower chainring. Lots of people, myself included, run 1/8" chains on a 3/32" chainring or sprocket on fixed-gear or singlespeed bikes (I do it b/c the sprocket is 1/8" and the chainring 3/32", or vice versa on another bike).

But I agree that it's kind of a waste to throw a 10-speed Dura Ace chainring on a fixie project. The main reason these chainrings are so expensive is because of all the machining and ramps and pins to make it shift better. And you want NOT-shifting. You should just get a cheap non ramped or pinned chainring wiht a taller tooth profile and sell your Dura Ace chainring on eBay.

Good info. I'll just sell the DA 7800 52t.
You're all right - it would be a waste on a beater!
