## What is chain tension?

A tight chain causes additional load on the chain which increases chain wear. Excessive slack causes chain vibration increasing chain fatigue. Proper chain tension is obtained by adjusting the chain. sag on the slack side of the drive.

## What happens if bike chain is tight?
