How tight is too tight to tighten a seatpost on a carbon frame? Mine is creaking but I can see small cracks at the bottom of the slot in the carbon frame.
Friction_Shifter said:are you sure you know where the creaking sound is coming from? could it be coming from the small cracks in the notch of the frame? depending on the design of your frame in that area its possible that tightening further could put tensile force down in the notch which could make it worse. I'm thinking the creaking is coming from there. A couple drops of oil would probably get rid of it, but I'm not recommending to do that. If that crack is the problem you want clean surfaces to fix it.
