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.

Park Tool Chain Wear Indicator CC3.2 is a simple to use tool that delivers. It is a "go/no-go" gauge with two different tolerances: 0.5% and 0.75% chain wear.. No moving parts makes it very reliable tool that most likely won't malfunction ever - unless you manage to bend it.
I have managed to ruin two cassettes because using too stretched chains. Won't happen anymore.

It is my opinion that this tool isn't as accurate as one my want to check chain wear. You can sort of use it as a guide but it lacks some persicion. Park tools has another chainchecker that's a little better than this but for the money I would pass on this. I do however like that this is a simple solution and can get you in the ball park of chain wear if you suspect its time, but by the time you have to check your chain you probably already know you need to replace it so id rather use the money toward buying a new chain than getting this to tell me something obvious

Быстро и просто. Влезло со стороной 0.75 - пора менять цепь, влезло со втрой стороны - можно ждать проскакиваний цепи по наиболее часто используемым звездочкам и начинать присматривать кассету.
