Chain wear monitor

Chain wear tester 415, 420 and 428

New control tool adaptable for motorcycle, scooter, moped and moped. This tool allows you to simply and quickly check the degree of wear on your chain.

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.
