⛓️ Stay ahead of the wear curve—because your ride deserves precision.
The Park Tool CC-4 Chain Wear Indicator is a precision-engineered stainless steel gauge designed to measure chain wear on all 5 to 12-speed derailleur chains, including SRAM AXS. It accurately detects wear at .5% and .75%, the critical points for chain replacement, helping cyclists maintain optimal drivetrain performance. Made in the USA and supported by a limited lifetime warranty, the CC-4 eliminates guesswork and extends the life of your bike’s drivetrain.

Nice Item - Does the Job
A chain checking tool is an essential part of your bike tool set, particularly if you have a crank driven e-bike.Once you work out how to use it does what it need to do.Usual Park Tool quality, probably a bit expensive for what it is, but will easily pay for itself in the long term.

Worth it to save your cassette
I initially believed this was counterfeit as there is a misprint on the sticker on the tool (it reads ">0.5" whereas packaging states "<0.5"), however this misprint is also visible on the manufacture's video of the tool.

Chain wear tool that does 11 and 12 speed chains
I had a chain wear tool, but didn't realise it was not compatible with 11 and 12 speed chains. Consequently my 11 speed chain wore more than I would have liked and it cost me a new cassette and chain rings. This wont happen with this tool hopefully.
