A worn chain shifts poorly and wears sprockets at an accelerated rate. The CC-3.2 is a "Go, No Go"gauge designed to accurately indicate when a chain reaches 0.5% and 0.75% wear, the point at which most chain manufacturers suggest replacement. If the 0.5% side fits into the chain it is worn 2/3 of 0.75% and should be replaced soon. If the 0.75% side fits, the chain is completely worn and should be replaced. The updated CC-3.2 is longer, more accurate and features permanent measurement markings. Made from precision laser cut steel. Fits all chains with a 1/2 inch pitch, including 10 speed chains.

Simple money saver

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.

This simple tool yields critical results.

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 good enough

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.

Easy to use

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.

Simple to use, gets used often

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

Easy to use ... best way to know when to replace chain.

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.

Easy, quick, and cheap

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.

Essential for every tool box

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.
