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.
