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

This thing is super handy. I had to buy one because I wanted to keep track of how much wear my chain has and when I need to replace it myself instead of taking into a shop.

Very easy to use. Seems like a must have for any DIY bike maintenance person.

Accurate and simple to use

I relube my bike chains every 100 hrs. The bike shop had me replacing the chain annually but when measuring chain wear using this tool I discovered that the chains showed minimal wear ... I could never come close to engaging the 0.5% wear position. I've subsequently started doing my own bike maintenance and use this tool to ensure that my chain wear never becomes excessive.

It doesn't get any easier to use. Just slide it into the chain and you'll know instantly if your chain needs to be replaced or not. It has two sides one for really worn out and one for almost worn out which allows you to plan ahead.

Not much to say. Works perfectly and it's not flimsy.

Park Tool chain checker is a solid product that just works. To top things off, it's reasonably priced and just as easy to use.

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.
