Features:
- Dirt Tricks chain wear gauge is a very simple tool to determine if your chain has reached its wear limit and should be replaced
- Chain*s replacement wear spec for 520 chain is 10.099* between 16 pins.
- How is works:
- Put your bike in gear and roll it backwards so the top chain gets tight.
- Hook a roller with the hook end of our tool and drop the indicator tip down onto the chain.
- If the tip of the gauge does not fit, its time for a new chain.
