Chain link (adding) question...

[SoCalSteve]

Hi all,

I have been running a 46t big cog now for awhile and want to go back to a 50t.

How many links do you think I need to add to the chain to compensate for the larger big ring?

As always, thank you all in advance!

Steve

4 teeth requires one inch of chain, but with modern flush-pin chains, you're not supposed to add such a small amount. You should start with a new chain.
