I learned a new trick from Cannondale. If you have an aluminum seat post going into a carbon frame:

• Pull the post and carefully remove the clamp assembly
• Clean the post and clamp thoroughly
• Clean the inside of the frame thoroughly (twisting a clean tightly wound rag lightly damp with some windex works well)
• Apply some grease (I used Marine Grease) to both sides of clamp, and all moving parts on clamp.DO NOT apply any grease to the seat post at this point.
• You can apply carbon paste to the back of the seatpost only if it’s needed.
