12 and 13 tooth sprocket?


Can I run both a 12 and a 13 tooth sprocket on the same chain?
I want to install a 13 tooth sprocket and swap to a 12 when conditions require different gearing without having to run a different chain?


The simple answer to your question is, 'Yes.'

Well...considering that your chain isn't too worn to start with. If you're around 6-8 on the snails with a 13T, I doubt you'd have enough left to correctly set a 12T.

I've changed back and forth a number of times. Takes all of a minute or two. Works fine.
