    My 2016 TCR Advanced 3 has a carbon fibre aero seatpost which has a little wedge device holding it in the carbon fibre frame : -

    I can unscrew the bolt fine, but the wedge won't come out, and I haven't been able to lift the seatpost out at all. It's stuck fast.

    Looking at the design of the wedge I can't see how I might be able to loosen it. I have only ever done it up to recommended torque settings.

    Any thoughts/tips ?

    I wonder if you could form a small enough hook to insert in the hole just enough to catch the edge of the top part of the wedge and pull up with a pair pliers of something. Perhaps a cut down right angled wall picture hook etc.

    Unscrew the bolt a bit, so it is protruding from the wedge, then tap it lightly with a hammer - that should loosen the bottom segment of the wedge, then it should all come out easily.

    I had the same issue when i first went to adjust mine, but as Smutchin suggests a few taps on the wedge and / or the seatpost will free it up. I use the plastic handle of a screwdriver. You don't need to be too firm.

    Thanks all, the lightest of taps and it was free again!

    That's a cunning design, inspired by the old steerers. Same small disadvantage though.

    I thought I might have really messed it up by having a little lithium grease on the seatpost but it came free very easily with a very light tap on the bolt. The design seems OK to me now I have been able to free it !

    I hate internal seatpost clamps and I'm not aware of any real advantage to the design other than being able to boost the bike's 'aero' claims - although I can't believe any of us would notice the negligible difference they make to drag.
