this broke my bike frame

I bought this to replace the seat post that I had as it was very heavy when riding. I used the shim that was supplied with the post so it was a tight fit and the post wouldn't slip down when riding....skip to a few months later my frame snapped under the seat post. Cracked and snapped the frame meaning I have to now buy a whole new bike as the frame is not safe even if I were to get it welded back together, it won't be safe to ride. So yeah, THANKS A LOT!!!! MOST EXPENSIVE SEAT POST I HAVE EVER BOUGHT, THE COST OF A NEW BIKE AND ALMOST MY LIFE..... I CERTAINLY WON'T BE BUYING FROM DECATHLON EVER AGAIN.

Value Seatpin

I've had two of these seatposts now on different bikes. Excellent value for money, and would have given 4 to 5 stars, but both posts failed after the two year guarantee ended. Definitely worth buying for a budget bike, but would recommend changing every two years.

Work out on any sport

Sports matter, i always get what i need.

Lightweight, sturdy.

My old seat post was totally iron, this one in comparison felt lot lighter. The sddle mount can be tilted and is held by two screws. This is my first time using such seatpost, therefore, how long the screws will suffice, remains to be seen.

No vale para diámetros anchos

Con el adaptador no funciona bien, la llevo super apretada y aún así se afloja del cuadro
