This is the first wear indicator that I have purchased. Precise use and accessible to all. It allowed me to instantly check the chains on 5 bikes. Result: three OK, one to monitor and one to change immediately (already late by several hundred/thousands of km, too late I didn't have this tool yet). Compact and very high quality despite a very reasonable price. It also allows you to hold the chain while you work on it.

C'est le 1er témoin d'usure que j'achète. Utilisation précise et à la portée de tous. Il m'a permis de vérifier instantanément les chaines sur 5 vélos. Résultat: trois OK, une à surveiller et une à changer immédiatement (déja en retard de plusieurs centaines/miliers de km, trop tard je n'avais pas encore cet outil). Compact et très qualitatif malgré un prix très correct. Il permet également de tenir la chaine le temps de travailler dessus.

I bought this meter because I doubted the reliability of the one I had when my last chain gave me a wear of 50% when it was new. This one seems more robust, so to speak, and clearer in interpretation. I have verified that the previous one was fine, but even so, I like this one much better, it makes the point of wear clearer and the extra one to hold the chain is very useful. So far the best meter I have used.

Compré este medidor porque dudaba de la fiabilidad del que tenía al darme en mi última cadena un desgaste del 50% siendo nueva. Este parece más robusto, por así decirlo, y de interpretación más clara. He comprobado que el anterior estaba bien, pero aún así, este me gusta mucho más, deja más claro el punto de desgaste y es muy útil el extra para sujetar la cadena. Hasta el momento el mejor medidor que he usado.

It's a good alternative to the lower priced tools from China that don't have any measurement accuracy. It has good accuracy and reliability in current measurements. Tool you buy once in a lifetime.

É uma boa alternativa às ferramentas de valor mais baixo da China que não têm qualquer precisão nas medidas. Tem uma boa precisão e fiabilidade nas medições da corrente. Ferramenta que se compra uma vez na vida.

One of the few easily available chain measurement guides which measures 0.5% which is what you should use for 11/12 speed gearsets. Not to much to say- reasonably priced and it works well.

Clear and simple gauge, if the first 2 teeth go completely into the chain it is time to change it, if the 3 go in, it is better to also change the chainring and sprockets.

Medidor claro y sencillo, si entran los 2 primeros dientes completamente en la cadena es hora de cambiarla, si entran los 3 mejor cambia también plato y piñones.

It does its job well. Made from thick steel with clear markings. Acts as a chain holder when you want to undo the quick link.
