    This may or may not apply to you...
    I've had problems with the seat post slipping on a 2009 6700 and a 2004 6700. The only way to get it not to slip was to use a salsa seat post clamp. On the new 6700 I even tried a bontrager clamp with a bolt and tightened it pretty darn tight, and it still slipped. Somehow the salsa clamps it down and it doesn't move. These were both aluminum posts... ymmv.

    I am 83kg full gear and riding 09 top fuel 9.9 (same seat mask system)
    I only applied 3.5-4Nm to hold the seatpost (with Finish line Fiber Grip and custommade cabon clamp)
    Check the size of seatpost and seattube inner.Maybe tolerance is too big.
    The size of my seattube have 0.4mm difference after tight up the clamp.
