Park ToolCC-3.2 Chain Wear Indicator(Return to Product Page)

I bought this tool after my shifts started to suffer. A quick check with the chain wear indicator tool showed that the chain was way beyond worn. I replaced the chain but the worn chain had worn out the cassette which skipped in several of the gears with the new chain. So I replaced the cassette also and it shifts like new. Spare yourself the cost of a new cassette, get this tool and check your chain often.

Having this product has helped me eliminate possible problem sources and zero in on where the real problems lay.

Great tool to have, when it's time to replace the bike chain or still have a little bit life left.

Well designed and simple, gives you the peace of mind that your chain in not causing unnecessary wear to your drive train.

Fool-proof way to decide if you need to replace your chain

Easy to use

Use this tool to see if your chain has stretched and is causing unnecessary wear on the more expensive parts of your drive train. This is made by Park, it's cheap, and it should be in your tool box or at close reach on your bench.

We have 8 bikes in the family, and I maintain them all. I used to check chain wear with a ruler, which was not very reliable and almost certainly resulted in some chains being replaced before they were worn out and others being replaced long after they should have been. With the Park CC-3.2, I checked all 8 chains in just a couple of minutes, and easily determined that 7 were good and one was completely worn out.

Yes you can use a tape measure to check your bikes chain but I like tools that make my life easier. The fast go no go use of this tool is really nice to have if you have more than a couple of bikes to maintain.

Very easy to tell if you need a new chain or not.

What can you say. The product works and every biker should have one.

For what it does, it's perfect. There are more thorough, sophisticated types of chain-wear tools out there, but this good enough.

Chain stretch is always something that is hard to gauge by just looking at it. This handy little tool is simple to use and does not break the bank. Just follow the instructions in the package and replace your chain when it says to!

No more replacing chains too early, nor too late.

This is a very inexpensive easy to use device to check for chain wear. While it is possible to use a tape measure, Park's chain wear indicator is easier to use and less prone to error

A super easy way to find out if your chain is good conditions to go on. But, because of the brand park tool is a little bit pricey, I found after I purchased this chain wear indicator, another from cyclo tools, half the price of this one.

Great tool in bring back to life vintage road bikes. No more guess work when it comes to the chain. Now I know if the chain needs to be replaced.

No more guesssing about chain wear.

I've always measured chains with a tape measure but I wanted something more precise. This seems like a good tool, it's simple and easy to use. I hate it when I space out and end up needing to buy and new cassette and chain. --Change the chain in time and get a year or more out of cassettes and chainrings.

simple to use, first chain gauge I have had
