Park Tool CC-3.2 Chain Wear Indicator

Its a Park tool, does what it is supposed to do

It was well built, reasonably priced, accurate, and easy to use.

Works as described.

I had been replacing chains on an annual basis just because "it's time". I read an article that said we could be wasting money replacing chains to early or causing damage because of waiting too long, so I picked up one of these wear indicators. Easy to use and probably saved me a little money because it shows that the chain I would have replaced is still in proper tolerance.

Waiting too long to replace your chain is a great way to destroy a cassette. This simple tool makes it easy to check your chain stretch, so you can avoid that expensive outcome. Park tools are totally trustworthy, so I'm glad I found this. I'm giving one to each of my kiddos so they can keep their bikes running smoothly.

The best tools are the easiest to use, doesn�t get much simpler than this one.

A simple, quick, and effective way to keep an eye on your chain and assist in maintaining your drive-train system.

Checking one's chain is a great idea since in the long run, it saves money. But just buy the Park Tool CC-2 Chain Checker Tool. It is a bit more expensive but much more accurate and provides better wear indication.

I finally broke down and purchased one of these. I usually replace my chain every 2000 miles. My current chain is approaching that mileage. I checked it with the CC-3.2 and discovered it is no way close to being worn out. I will save money in the long run.

Nice thing to have in your tool box.

Very easy to use, just takes a second to evaluate the chain for wear. Because it's so simple it actually gets used. Seems expensive for what it is but preventive maintenance is cheaper than replacing the cassette

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.

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

Tool works well to check chain ware.

Accurate and simple to use

I've elevated from committed recreational rider to dreams of the banging bars in the peloton (not really). I've upgraded my bike and mileage efforts, so keeping my drive train healthy came along with my commitment.

This tool does the trick for all of my bikes. Simple and easy to use - BTD is a benefactor of my need for chains and the occasional cassette. I'll provide the labor.

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

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.

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.
