I am sure this has been posted before, but I am having a slow slippage of
the seat post down the seat tube resulting in a changed riding position. I
have already tightened the seat tube clamp to the max. Any suggestions for
a friction solution to keep the seat post in place without ruining the post
or the seat tube?

Tacx makes some 'stuff' for carbon/carbon applications to prevent what
you are seeing. See your bike shop or call us..we have it for sale.
