CC-4

Correct chain gauge for checking SRAM T-type flat top chains. Gets plenty of use and no signs of wear. Not cheap for what it is but regularly monitoring your chain wear will save you money in the long run.

Simple , accurate and effective for 12 speed SRAM chain. Good quality like all Park Tool kit

Perfect for measuring the chain on a SRAM Eagle 12 speed setup, as it's park tool, it can be trusted for it's accurancy, which in turn should lead to more life out of cassettes and chainrings.

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

Expensive but park tools can be trusted to be accurate in the machining profile of the tool unlike the cheaper options

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.

Another great product from park tools . You do need to read up or watch video on how to use . And it just does what it says it does . I have bought to check E-Mtb chain

The usual park tool quality,a bit pricey but it's probably the most accurate 1 you can buy,wouldn't trust anything else with such an important measurement.

This chain wear indicator is more accurate than the two point design as it eliminates roller wear from the measurement showing actual stretch (pin wear). This is the measurement that is important.

Gute Qualität!

Pros: ✔️ Very easy to use ✔️ Longer measuring span reduces error ✔️ Solid and precise build ✔️ Quick chain check in seconds Cons: ✖️ No real drawbacks for this type of tool Review: It simply does what it’s supposed to do. The tool is straightforward and very easy to use — you can check chain wear within seconds. A big advantage is its length. Because it measures over a longer section of the chain, it minimizes measurement error compared to shorter gauges. This gives more confidence in the result, especially when maintaining drivetrain components regularly. Overall, a simple but essential tool that works exactly as expected.

Easy way to see chain wear if the end point slips into the chain linkage. Keep your chain clean and lubricated and it will last much longer. An overly oily chain attracts dust and forms a paste that wears out your chain faster and will cost you money to replace.
