Hi, yesterday I bought a 17t surley cog from my local bike shop to change the stock 16t on my kilo chrome stripper. I'm quite new to doing all my mechanic and so I tought that it would fit easily but later I found out that the kilo chain is 3/32 while the cog I bought was 1/8.

My question is, should I return the cog and order a 3/32 online (because they don't have it in stock) or should I upgrade my chain to 1/8.

Are there any benefits to upgrading from 3/32 to 1/8? I've read somewhere that 1/8 is standard for track bikes.

Thank you!

1/8 would be the better way to go. Then again, you'd need to also upgrade your chainring as well as the chain. It's up to you. I personally would run 1/8 which I am. It's slightly more thick than the 3/32 and it feels beefier.

Would I be able to use my 3/32 chainring with the 1/8 cog and chain for a while? Money is kind of tight but I don't mind investing in the good stuff.

Yo can keep your chainring if you get the 1/8" chain.

I did the exact same thing a few years ago and got a 1/8 Surly cog! I changed to a 1/8 chain (8-10 bucks) and everything is fine. My chainring is 3/32. Been using this setup for more than 2 years and had no problems.
I personally can't tell a difference in performance.

1/8" chain can work with both 1/8" and 3/32" cogs/chainrings. Personally, I would use the new Surly cog that you already now have and get a 1/8" chain. You should be able to find one for not too much $$.

Keep cog, change chain. Yes, yes.

Thanks everybody! I will sure do so (keep the cog and get a new chain). Eventually I will upgrade my chainring, probably when I upgrade my crankset.

A new crankset will most likely come with a new chainring, so look for 1/8" chainring when doing so

No need to rush with the chainring. We ran a 1/8" chain with 3/32" rings for the timing chain on our tandem for tens of thousands of miles with no ill effects. The 1/8" chain seemed to last much longer than the narrower chains.

I ride SS/FG for commuting purposes and I have discovered that I have a much wider selection of parts by running a straight 3/32 drive train rather than going for a 1/8 track setup.

absolutely. and it's much more forgiving of any chainline issues. and it's lighter. and you can run a non-144bcd crank.

yes, it does.
