Unior Chain Wear Tool

Unior chain wear tool perfect for keeping your bicycle's drivetrain in optimal condition. Made from precision laser-cut steel, this gauge accurately measures chain wear at the levels where chain manufacturers typically suggest replacement (0.5% and 0.75%). The three-point tool design isolates pin wear from roller wear, ensuring accurate results. Use the QR code to view the instruction video. Works on all 6-13 speed chains, including SRAM flat top chains. As a general rule, 11 to 13-speed chains should be replaced at or before 0.5% wear, while 6 to 10-speed chains should be replaced at or before 0.75% wear.Features:It is important to monitor chain wear, as a worn chain can cause poor shifting and wear out other drivetrain componentsMade from precision laser-cut steelAccurately measures 0.5% and 0.
