Hey, my seat post got those weird seat clamps to tighten it.
After 1 year of cycling i wanted to move my seat up a bit but i just cant get this Screw tightened again, whats the issue?
If i take the seat clamp out i can tighten it, but once its inside to actually hold my seat it wont tighten.

Hey, so i wanted to move my seatpost a bit higher, unscrewed this bolt and set my seatpost higher.
Now i wanted to Scre it in again bit it just wont tighten, and i dont know why. I feel helpless and i feel like its an easy solution. Outside of the frame i can easily tighten this screw, but as soon as i get that thing in it just wont.

Im just unsure if it looks alright or not.
Sometimes i feel a bit of discomfort in my back area.
