Unior Pro Chain Wear Indicator Tool

The Unior Pro Chain Wear Indicator Tool helps you quickly and accurately measure chain wear and stretch so you can replace your chain at or before the recommended 0,6% stretch. Simply insert the checker pins into two chain links, press the swing arm gauge tight, then read the result in the gauge window for a clear, reliable assessment. Using the Unior Pro Chain Wear Indicator Tool helps you keep shifting crisp and reduces uneven drivetrain wear, saving you from premature component replacement.
