I have an USE Alien seatpost installed on my Cannondale frame. The problem I have is that the carbon post is always slipping into the aluminum frame. The seatpost clamp has been tightened without a torque wrench, just by feel like all other seatposts I've ever installed. Is there something I should know about a carbon/aluminum interface? Before you tell me to tighten the clamp some more, the seatpost clamp is actually tighter then on my other bikes (by feel). I just don't want to get frustrated and over-tighten the clamp and somehow damage the carbon post (ie. crack it).
