Checking your chain for wear is one of the simplest things any cyclist can do to maintain drivetrain performance and minimize maintenance costs. The Pedro's Chain Checker Plus makes this task quick and easy offering a simple worn/not worn measurement which tells you if your chain should be replaced. To ensure the maximum life from your chain and accuracy of measurement, Pedro's implemented a three-point design which properly isolates pin wear from roller wear. Other two-point designs do not and can incorrectly indicate a worn chain, robbing the user of additional miles and money. Not content to offer only chain wear functionality, Pedro's included a chain hook tool, perfect for simplifying chain removal and installation, and a chainring nut wrench, essential for removal and installation of chainrings.


  • Precision laser cut design accurately measures 0.75% chain wear
  • Three point chain wear tool design properly isolates pin wear from roller wear
  • Chain hook tool and chainring nut wrench add functional versatility and value
