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 minimise 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.



  • Precision laser cut design accurately measures 0.5% and 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


Mark Clearly shows your chain stretch.
neilB Not cheap but this clever design checks pin wear only rather than the “normal” checkers that also read roller wear . Pin wear is what allows a chain to seem “stretched”
Mr hunter Ideal to keep an eye on your chain, simple and easy to use
Mr Nicholas Ordered this after reading a review of chain checkers on CyclingTips web site. It's better than my old ParkTool version that can't cope with chains for 10-speed cassettes.
KM The tool is good in that it isolates roller wear from chain stretch. I do find the notches on the wear checker hard to discern if it is showing no wear or .5. Thats my only issue. The chain holder part is a bit useless - a paper clip is more effective.
Mr Chia Another item that is multiuse from Pedros. Saves me space in the toolbox.
