Quickly and accurately -ZTTO Chain Checker.

To alleviate poor shifting and uneven drive train wear, manufacturers recommend chain replacement before rear cog replacement. Now you can quickly and accurately determine the wear and stretch of any chain with the ZTTO Chain Checker. Simply insert the Chain Checker’s pins into two links, lightly press the swing arm gauge, and then check the gauge window for an accurate reading, the chain wear indicator will determine if your chain needs to be replaced. Over a period of time every chain will stretch resulting in poor shifting and the high possibility of the chain snapping.

Full compatible

The LTJC-001 is compatible with all derailleur chains. For 9 and 10-speed chains, replace chain at or just before the 0.75% readings. For 11 and 12-speed chain, replace at or just before the 0.5% reading. Check with manufacturer for specific replacement instructions.
