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

simple to use, first chain gauge I have had

At roughly 1,700 miles I had a chain snap while taking off from a stop. When the chain snapped it broke my front Di2 derailleur and luckily I didn't go down in the process or get hit by oncoming traffic. Do yourself a favor and check your chain when your miles start adding up...

Every cyclist needs to know when their chain needs replacing. This tool is an inexpensive tool to have in your box. There are other more costly tools, but I don't know why you would use them when this is more cost effective.

Park Tools always work and I have not had any problems, plus it is small enough to travel with. Gono-go tools are the best. You don't need to worry about moving parts or calibration issues.

Bought not know Ming my chain wear. Found out that I needed a new chain, promptly changed the chain. Helped reduce the noise of my drivetrain

A great away to check chain wear very quickly with no confusion.

Easy to use. Eliminates guessing.

nice to have the tool in my toolbox, use it and it works, simple peace of mind

I use it to check chain wear. I used to just measure between the rivets to check wear. This tool tells it like it is.

Nothing to dislike about it at all.

Works as described.

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

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

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.

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

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.

Tool works well to check chain ware.

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
