Measure chain stretch with a chain wear gauge
Measure how much your bike chain has stretched with a chain wear gauge, which is more precise than guessing.

What you need
- Chain wear gauge
How to do it
- Tension the chain with a little pressure on the pedal.
- Place the shorter pin of the gauge between two chain rollers; the gauge has a notch for this.
- Lay the gauge on: if the front pin drops halfway or fully into the slot, the chain is nearly or completely worn out.
Variations
- A gauge costs roughly 20 to 30 euros; the investment is said to pay off because you use it again and again.
