How to Check Your Chain for Wear

Measure your mountain bike chain to detect wear.

The internal parts — the rollers and rivets — of your bike's chain, wear out with use, and a worn chain can take a toll on your drivetrain, negatively affecting shifting and causing premature wear on your cogs and chainring. Replacing your chain before this happens can save you money, and it's easy to measure chain for wear on a regular basis.

There are a few different methods for measuring wear, including lifting the chain off the front chainring to measure the distance between two rivets on your chain, or by using a chain checker tool or ruler.

Our techs can also help you determine when it's time to replace your chain, and when you bring your bike in for service, chain wear is something we check as part of our inspection process.
