It’s made by kmc. I

I change chains every 1500 miles by which time the kmc x8 is usually approaching 0.075% wear limit. I’ll see how this one goes. I don’t know yet hence 4 stars.

Bike's chain broke just opposite Decathlon store. Lucky me.

Die Kette macht einen guten Eindruck. Leider lässt sie an der Gravur nicht erkennen, wie rum man die Kette montieren muss. (Beide Seiten sehen gleich aus) Und das Kettenschloss lässt such auch mit großen Kraftaufwand bis jetzt nicht vollständig schließen. Deswegen konnte ich keinen längeren Tests machen.

La cadena no sirve para bicis eléctricas

La cadena es bastante endeble

Hola Miguel Ángel,

Agradecerte el tiempo que te has tomado en exponer tu valoración sobre nuestro producto.

Siento que la cadena escogida no haya cumplido con las expectativas.

Este modelo de cadena ofrece un buen rendimiento en bicicletas sin asistencia electrica. Para este tipo de bicicletas disponemos de cadenas más resistencias y diseñadas para dichos modelos.

Te aconsejo aproximarte a tu tienda Decathlon más cercana para que el equipo de ciclismo pueda atenderte y cambiar el modelo si lo deseas.

Espero que podamos ofrecerte la cadena que necesites para la transmisión de tu bicicleta y devolverte la confianza depositada en nosotros.

Un cordial saludo, que tengas un buen día.
