Bicycle chain wear monitor

Bicycle chain wear tester

New control tool adaptable for MTB, VTC, road, electrically assisted bikes (E-Bike, VAE). This tool allows you to simply and quickly check the degree of wear on your chain, in order to maintain a smooth transmission and extend the life of your chainrings and cassette.

To measure wear, simply position the tool between the links: if the lugs are not placed between the links, the wear of the chain is less than 75%. If the lug 0.75 slips between the links, the chain is 75% worn, in this case, only the chain needs to be replaced. If the lug 1.0 slips, this means that the gap between each link is 0.10 mm, in this case, the bicycle cassette must be changed at the same time as the chain.
