Chain compatibility

So i recently purchased a wheel set fit with an 1/8" cog and threw it on my old road bike.

I shortened the chain and everything however the teeth don't seem to accept the chain in a smooth manner. The chain is the same one that came on the old road bike. I'm guessing its a 3/32" chain.

My question is: Since the rear cog is 1/8" could the be the reason why the 3/32" chain doesn't move smoothly ? Could a 1/8" chain fit both the rear cog and the existing 3/32" chainring in front ?

1/8" cog has teeth too wide for the 3/32" chain

I'm guessing the 1/8" chain will work on a 3/32" chainring. I'll let someone else give a definite answer

[edit]

aren't 1/8'' cogs used in bmx?

I don't believe so. Sheldon says their usually found on track bikes whereas, 3/32" are usually found on old road bikes like mine.

I stupidly bought the wheelset with 1/8" cogs without realizing the chain probably wouldn't fit.

Yeah. Hopefully the 1/8" chain will just fit on my current 3/32" chainring for now because when i save up some money i'm looking to invest in a new crankset. So getting a 1/8" chain now that works with my current situation would be optimal.

Anyone have an answer as to whether the chain will fit on a 3/32" chainring ?

1/8" chains work fine on 3/32" cogs/chainrings. The opposite is not true.

Awesome. Would it still work fine with 1/8" cog in the rear and 3/32" chainring in the crankset ?

I'd guess yes. But i want to make sure because i already made one stupid purchase

Yup. No worries. That's how my FG is set up.

I got surprised by the same thing with my first fixed wheelset. It came with a 1/8" cog and I had planned to use the existing chain, but had to buy a (SRAM) ss chain. I'm also running the existing 3/32" chainring on three fixies I converted.

1/8 is usually a bmx chain. it works fine for track stuff, but it will look super beefy compared to 3/32.
