Key Features

Laser Cutting Precision

The tool's laser-cut design allows it to make contact with the chain at three separate points, ensuring the most accurate measurement. This makes it easy to determine the true wear condition of your chain.

Wide Range of Compatibility

The CC-4.2 is designed to work with almost all modern bicycle chains:

• 5-10 speed chains

• 11-13 speed chains (including SRAM Flattop and Campagnolo Ekar)

• single-speed chains

Three Separate Wear Indicators

It shows how worn your chain is on three different levels:

• 0.5% wear

• 0.75% wear

• 1.0% wear

Protect your expensive pieces.

Regular chain checks can extend the life of your cassette and chainrings. Continuing with a worn chain will cause these expensive parts to wear out quickly.
