Are you wondering when to replace your chain? The Park Tool CC-3.2 Chain Wear Indicator makes it easy to know when it's time.

This lil' guy was made solely for the task of determining chain wear. To check chain wear with the CC-3.2, locate the end of the tool with the 0.5 stamp. Install the hook end on a link with inner plates to ensure you’re measuring against the roller and not the side plates. Attempt to install the other end into the chain.

Not going in? Your chain is not yet 0.5 percent worn. If it does insert into the chain, it means that your chain is now at least 0.5 percent longer than when it was new. Flip the tool over to check if your chain is 0.75 percent worn. If it doesn’t insert into the chain on the 0.75 percent end, your chain is not yet 0.75 percent worn.

But wait. So when do you actually need a new chain? Anything at or beyond the 0.75 percent reading indicates that you should swap out your chain for a new one immediately. If you are using a chain designed for ten or fewer gears, replace your chain as it nears the 0.75 percent mark. If you are using an eleven or twelve speed chain, replace your chain once it has reached 0.5 percent wear. For two-sprocket or single speed bikes, replace your chain as it reaches the 1 percent wear mark.

Are you ready to check your chain wear with the Park Tool CC-3.2 Chain Wear Indicator and possibly replace your chain?

You know where to go.. ;)
