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 .5% and .75%, the points at which most chain manufacturers suggest replacement. The updated CC-3.2 is longer, more accurate and features permanent measurement markings.

Rated 5 out of 5 by tworldsmine Slightly overpriced but very useful tool
It must be one of the best chain stretch tools I have owned. Simple gauge (0.75% and 1%) delivers straight forward reading. It is a bit too pricey but nevertheless a great tool that simply is to be had.

Rated 3 out of 5 by ukrbublik Useful, but overpriced
Useful tool? Oh yes! Does the job precisely.
Is price good? No, 13 bucks for a such simple piece of steel, really?

Rated 4 out of 5 by Bernard76 Its a simple and straightforward way to tell if your chain is worn
Great and simple to use with two indicator markings on the side : 50% wear, 75 % wear. So if the teeth fits inside the chain...you know you'll have to replace the chain. Why replace the chain? Because its really a no-brainer to replace your beautiful and expensive XT/XTR cranks or cassettes just because of chain neglect ! I guess replacing a chain is much much cheaper right !
After I got the tool, started to measure for my friends when they pop by my house too ! So far so good.
For some of you guys who likes enjoying the rough rides but never seem to maintain your bikes, this tool might just be the saving alarm to send your bike to your local bike shop if you periodically use it for time to time!

Rated 5 out of 5 by Ricker Great product, keeps your mind at peace
Its more of a peace of mind tool. Although the price is high for such a device, it does do its job well, is marked well, and helps you feel at peace knowing your chain is or isn't worn out.

Rated 4 out of 5 by Zoslen Good enough
Robust enough and counts 0.5 and 0.75, while other chain wear indicators count 0.75 and 1.

Rated 5 out of 5 by PaulShouldknowbetter Will save you pounds
Its only a flat piece of pressed steel, but it will pay for itself many times over. It even has a second use - as it is excellent at pushing worn out brake blocks from the holder while on the bike ( the little c part fits the radius on the back end of the pad perfectly).
Change the chain between .5% and .75% wear and you can prolong the life of the cassette by being able to use at least 2 chains to one cassette. If you let the chain wear much beyond .75% you will have to replace the cassette every time.

Rated 5 out of 5 by lbalc You need this tool!
If you don't have this tool you will not know when your chain has worn out, meaning; you have to buy a new cassette, a new chain and in my case a large chain ring (as that is the one I use the most on the front). Had you spent under a £10 for this tool, you could just change your chain (£15) and got 2-3 chains out of the cassette and probably 4-5 out of the chain rings. Otherwise it's spend more like £70 in new parts.

Rated 5 out of 5 by RobbyD simple and effective
A very simple tool that is a good addition to the tool kit.
Takes the guess work out of changing a worn chain before it causes damage to other components
Should help save money in the long run.
