Chain Wear Check Tool, Chain Hook Tool, and Chainring Nut Wrench

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 II makes this task quick and easy offering a simple check of 0.5% and 0.75% chain wear. To ensure the maximum life from your chain and accuracy of measurement, the tool employs 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.

The Chain Checker Plus II also includes a chain hook tool, perfect for simplifying chain removal and installation, and a chainring nut wrench, essential for removal and installation of chainrings.

Works on 1-13 speed chains. Chain wear tool approved by SRAM® for use on EAGLE® 12-speed and Flattop chains.
