I have a seatpost with spring suspension. Something like this one:
A friend of mine hit it with his leg while he was dismounting and broke it into two pieces. After putting it back, I noticed that the plastic piece that holds it together has a broken thread. The bike is about 1 month old, so it is still under warranty.
Should I leave it as it is and hope for the best, or should I go back to store and ask for a new one, alleging bad manufacture?
Also a plastic ring it is clearly to weak for that join should I just get a simple seatpost ?
