A simple tool to use
Easily check bicycle chain wear. Just gives a basic check other tools maybe give more of a reading of how much wear.

Does what it is intended for.
Tested on a new chain and one with wear, accurately measures and helps you know when to change the chain.

Good product
I have tried other products, but they're not a sturdy as this one. Value for money.

Do not buy if you have a SRAM AXS Flat top chain.
Despite the description saying that this is compatible with 12 speed chain, this turned out to be useless for my 12 Speed SRAM flat top chain. If you have a flat top chain you will want to buy Parktools’ CC-4 that is compatible with flat top chains. Besides the incompatibility for my use case, the product itself seems quite nice and solid feeling, and I would recommend to users with Shimano chains.

fonctionne bien pour mesure l'usure d'une chaine et pour installer des quicklinks sur une nouvelle chaine.

It's simply a thin flat piece of steel that you slot into your chain, one end of the device is shaped to enable easy insertion into your chain whilst the other end provides a wear measurement as you bring the end into your chain. I was very quickly able to determine by inserting the device that my chain was worn to the bejesus and (a measurement of 1.0 or over) requires immediate replacement.

Ottimo calibro. Ho apprezzato la sua funziona e la precisione. Consigliato.

Había probado otra del Ali y media lo mismo en 0,50 que en 1, esta la medición es fiable en comparación con un calibre micrómetrico de taller. Es caro para ser un trozo de chapa, pero es que si lo compras más barato no vale de nada
