Having some problems with my seat. I have a Cube Analog Disc 2012 bike, the blue color-scheme. After only 100km, the seat started creaking. I sent it back to the shop and received a brand new seat instead. But unfortunately, after another ~200km, the seats started creaking softly, but I believe that in a few days, the irritating creak from the first seat will come back.
It's worth mentioning, that the creak comes from right under the seat, from the plastic that sustains the fabric; right between the front and rear supporting points. Also, I have only 66kg, so weight is not the problem.
I've included a photo so things would be clearer.
Has anyone stumbled upon this issue? What should I do? I believe it's not a solution sending the seat back for replacement once every two weeks...
