Unior
Pro Chain Wear Indicator

The Easiest Way To Determine If It's Time To Replace Your Chain

To alleviate poor shifting and uneven drivetrain wear, most manufacturers recommend chain replacement at or before 0.6% stretch.

Now you can quickly and accurately determine the wear and stretch of any road, MTB, gravel or e-bike chain with the Unior Pro Chain Wear Indicator.

Simply insert the chain checker's pins into two links, press the swing arm gauge tight, and then check the gauge window for an accurate reading.
