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

  • 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.
  • Chain wear tool approved by SRAM® for use on EAGLE® 12-speed chains.


How to use:

  1. Position the Chain Checker just above the chain and hold in place with one hand.
  2. Use your free hand to push the chain up onto the Chain Checker at position 1 so that a roller is cupped by the curved protrusion.  Hold in place.
  3. Push the chain firmly onto the Chain Checker at position 2 to create tension in the chain between between the rollers at positions 1 and 2.  Continue applying pressure on the chain upward at position 2 and release your hand from position 1.
  4. Finally, while keeping pressure at position 2, push the chain onto the Chain Checker at position 3. If the chain is worn more than 0.75%, the protrusion at position 3 will go through the chain past the roller.  If you cannot push the protrusion through the chain at position 3, then the chain is worn less than 0.75% and is still OK to use.
