This is one of the best tools for checking the wear of my bike chain. I’ve been using it for quite a few months now on my brand-new bike to know when I need to replace my chain. After about 600 miles, the Park Chain Checker Tool measured at .50 so I knew it was time to replace my chain. This process is integral to ensuring you don’t wear out your cogs too quickly. A worn out chain can cause shifting problems as well so you always want to stay on top of replacing your chain. The quick functionality of the tool is great. You can tell if your chain needs to be replaced within seconds of using the tool. The size of the tool is very compact so you can store in your kit if you want to ride with it (although I wouldn’t see why you would need to). The design of the tool makes it very easy to use and quick to understand. It’s also very durable and well built. Great tool. Read more

This Park Tool chain checker is simple, awesome, and worth every penny. It only does one thing, tells you when your chain’s worn out, but it does it perfectly. If you ride regularly, this thing is a must-have. It’ll save your drivetrain, your wallet, and your pride when you realize you’ve been grinding miles on a chain that’s basically a worn noodle. I’m a garage-maintenance kind of cyclist, so this one lives right next to my torque wrench and caffeine stash. Doesn’t make coffee, doesn’t look flashy, just does its job better than I do mine on hill repeats. 10/10 — small tool, big value. Read more

Funktioniert, fühlt sich hochwertig an, idiotensicher. Mehr brauchts nicht. Tolles Tool Read more

Excelente herramienta para comprobar con rapidez y precisión diversos grados de desgaste de cadena. Antes de comprarlo pregunté en la tienda donde me reparan la bicicleta si era mejor este medidor o uno fijo, y me dijeron que es mucho más preciso y fiable este modelo de Park Tool. Me hizo una demostración con un par de aparatos, entre ellos éste. Aunque el precio no es barato puede ahorrarnos bastante dinero en averías. Read more
