HOW TO USE THE TOOL:
- To alleviate poor shifting and uneven drive train wear, most manufacturers recommend chain replacement at or before 0,6% stretch. Now you can quickly and accurately determine the wear and stretch of any chain. Simply insert the chain checker`s pins into two links, press the swing arm gauge tight, and then check the gauge window for an accurate reading.
