Re: Chain Conversion

[Christopher May]

Rear sprocket definately needs replacement.

There are those of us who think that, in normal circumstances, BOTH sprockets should 
be replaced when the chain is replaced.  Sprockets don't cost that much and the new 
chain gets the chance to set its own wear pattern instead of having to try 
(unsuccessfully, usually) to adapt to the old chain's wear pattern.  And there are 
also those of us who think that chains are a pain in the a** and should be outlawed.
