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.

Measures chains as expected. Easy to yse

Easy to use and goes to 0.5 wear
Good quality chain wear indicator, as to be expected from Park. Easy to use and measures down to 0.5 wear, when most others on the market start at 0.75, by which point your chain is already too worn for most 11+ speed setups...which most bikes are these days.

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.

High quality make
The tool is high quality make and seems to be very accurate. However, it's a bit pricey.

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.
