None. It's done all the time, though usually with a 3/32" chainring and 1/8" rear sprocket. Presumably narrower sprockets will wear faster but it's not like you'll likely notice.

actually, 3/32 chain ring and 1/8 rear cog is what im doin right now. i should have been more specific. if i instal the back cog i'll have 3/32 front and back with a 1/8 chain running on them. will that cause me any trouble?

Still no issues, though whe it comes time to replace the chain, you might as well go to 3/32"

Hi,

Go with a new chain with a new rear cog, unless your chain is relatively new.
If you don't you'll just rapidly wear the rear cog to the same state as the chain.

rgds, sreten.

that I do know. thanks all the same though. it's a pretty knew chain so it should be all good. i had just bought a new chain and bottom bracket and after installing them at my homies place i was rummaging through his parts bin and found the cog. I was already planning on pickin up a 15 so i figured as long as it wont be an issue i might as well save myself a lil loot.

anyway thanks all. cheers.

1/8" is 4/32" after all.. that 1/32" aint much ..

Full Bushing Chains are longer Wearing, in single speed drivetrains, but finding any in 3/32" these days, is rare.
