Bicycle Chain Wear Meter - Unpacking, First Look

Bicycle Chain Wear Meter with Aliexpress - Unpacking, first glance.
In this video I will show you a tool with which you can measure the wear of a bicycle chain. If you do not change the bicycle chain in time, then the stars of the system may also wear out and you will have to change them along with the bicycle chain. The front stars of a bicycle system usually take longer to wear out than the rear ones. The wear gauge of the bicycle chain will show when it is necessary to change the chain so as not to bring it to the replacement of the rear stars on the bike. You can use two chains on a bicycle and change bicycle chains in a circle so that the stars of the system live longer.
