3/32 chain and cog 1/8 crank?
i went and got a 17t cog yesterday but they only had 3/32 and so the lbs dude was like you can run a 3/32 cog and buy a 3/32 chain and you will be fine even though the crank is 1/8. he said it will work fine as long as i dont use a smaller chain.
has anyone else ever ran different sized drivetrain parts? how did it work out?
is this legit? like is it gonna some how kill on me? i saw this dudes post and he said he had wrong cog and it broke and he got messed up.

Your LBS is wrong. Go back and have him show you how to use a 3/32nd chain on a 1/8 chainring.
Your can run 1/8th chain on the 3/32 cogs and chainrings if you need to but not the other way around.

maybe i got it it confused. he put it all on.
okay i just checked the box and i got a 1/8" chain and cog and i got a 3/32 crank.
the crank is the stock crank on the kilo tt.
now that thats cleared up and i have a 1/8 chain and cog and a 3/32 crank will i be okay?
and will it still work correctly? or is there anything i should look out for?

Yeah, fail.
I run a 1/8" chain and cog that works just fine with a 3/32" chainring.

3/32 vs 4/32 isn't really a significant change in width. I think that a 3/32 5/7/8 speed chain would work ok, but a 9/10/11 might not.

Wrong again. All 3/32 derailleur chains, those marked 7,8,9,10 speed will work with 3/32 cogs/chainrings. The inner diameter, where it actually matters does not change as you go up in speed. Only the outside.

What I was saying about the 3/32 chain is you can probably get away with running 3/32 chain made for old 5/6 speeds since they would have less prescise tolerances vs the newer 8/9/10 speed indexed stuff thats going to have closer tolerances due to indexed shifting. Thats what I did at least.

Well, my bike came with a 1/8in chain, 1/8 freewheel and chainring, and all I did was switch out the rims and put on a 3/32 chain and cog. It worked fine, aside from making a small amount of noise. I checked the chain when I removed it and it had very little sign of any wear.

Your bike will make terrible noise if you use 1/8 chain and anything else 3/32.

Where are you from? Yesterday i bought a 17t cog and they gave me a 1/8th when i needed a 3/32. I got to go back to santa cruz to exchange it. Wanna trade if you live nearby? Im from San Jose, CA
