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 ?
