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.

excellent Seat Post

light and easy to carry and swap seats

Good quality had to return owing to size

Quality is good, but description doesn’t state usable sizes (how much of 330 mm is to be kept inside frame at min), had to return as it wasn’t long enough for me

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.

Incompatible with my Elops 120

Would be good if they highlighted what bikes these are compatible with, as the width of this was not compatible with my Elops 120 city bike. Even though build quality and looks seem pretty good, disappointed to find out it couldnt fit when I was trying to set it up

Bad Seat Post

Bought the seat post intending to resolve a worn out post issue . The new post did not work as the female part (on the bike frame) also wore out . This means the new post was too thin for the hole on the frame and thus thens to slip when sitting on the seat . The engineer attending should know that the female part also can wear and at least check the wear with a caliper before recommending the seat post purchase (the whole bike was bought into the store - Mountain Bike was bought from Decathon).
