If you swap cassettes do you need two chains?(2 posts)

If you swap cassettes do you need two chains?JL
Jun 7, 2002 11:07 AM
With the discussions about having two cassettes for different riding situations or 2 wheels for different situations, do you need a chain to "match" the different cassette? Or would this only matter if you made a big jump between cassettes? Knowing you can sometimes have problems when changing a chain without a new cassette due to wear, does it matter? Or does it depend on how often you switch between them?

Thanks in advance. Happy riding.

First, the chain has to be long enough to cover the big/big sprocket combination for whatever cassette is on the bike.

Second, if you replace your chain before it gets too worn, say whenever two pins are between 12 1/16 and 12 1/8 inches apart, you should be able to interchange cassettes without any concern.
