how do you interpret the result?
If the tip of the tool (the right-hand part) does not go beyond the line above the \"OK\" sign, then your chain and cassette are in perfect running order. If you press the right-hand tip of the tool in between the 2 lines of the \"1\", then you need to change your chain. If you press the right-hand point of the tool beyond the line at the start of part \"2\", then you need to change your chain and cassette or freewheel.
Pro tip:
This chain wear indicator is a precision tool. If the tool is dropped, this could affect its precision and the result obtained. Be careful when handling the tool and protect it from being dropped.
Compatibility:
Compatible with 5- to 12-speed chains.Not compatible with the SRAM Flat-top chain.
Made in:
Slovenia
How to use this tool.
Place your bike on your workshop stand (for greater comfort) or against a wall. Insert the left-hand side of the tool into a link on your chain (make sure the small hook is well inserted into the link), then lower the right-hand side onto the chain to read the result. Once it has been properly installed on your chain, the chain wear indicator should lie as flat as possible.
How often should you use the tool?
Depending on how often you ride, it is advisable to check the condition of your chain once a month.This will ensure smooth gear changes and limit premature wear on the cassette or freewheel. As wear can vary depending on the area, take several measurements on different sections of the chain.However, avoid the section with the quick release, as this could distort the result.

Product Reviews


I bought this while collecting an order from Decathlon as I wanted to check the wear of my chain (~1000km in). When I did use it (as the video instructed) on my 11 speed chain it indicated the wear was greater than 0.5%, almost 0.75%. I then got a bike shop to check with their park tool version and it showed barely 0.25%! Unfortunately I binned the receipt so can't get a refund - what a waste of £3.99
light weight, great value and easy to use.
This item is unreliable it is not accurate and indicates chains are past .75 worn when in-fact the chain is not even past 0.5% As a result of this i have been wasting money replacing chains earlier than they need to be changed when they still have a lot of life left on them I have now purchased a Park Tools cc3.2 chain checker which is far more accurate and reliable
