Any suggestions?
Nope, but hopefully someone has as mine has fused in also and like my seatpost I’m a touch stuck!

near Chorley. He’ll sort it.
Seatpost man recommended here mate.
My tale of woe is here:
https://singletrackworld.com/forum/topic/a-little-vent-1/
(Note: STW now randomly shuffles posts around so it's a little hard to read the thread. In summary, it wasn't going to move for anyone. I used a local bike mechanic, who had to delicately cut the post out of the frame and, after examining the bits, it was pretty clear that it wouldn't have shifted any other way. Still using the bike (with a new post!) 12 months later, so was well worth the effort)
i too have used the seatpost man, nice chap and got my post out in about an hour... whilst i waited (and by waited i mean i went to leisure lakes bikes and gawped at their showroom as it's just round the corner)
he saved both the frame (alu) and the post (carbon)
I'm wondering if it's worth bothering: It's on my DH bike and I never need to adjust the saddle, which is also why it's seized. The only reason I noticed it is I was packing it for the plane and it wouldn't fit in the box with the saddle on. In the end I just took and saddle off and it fitted.
Similar problem hear except cheap steel frame and nothing worked so tonight I'm going to start to react/disolve the seatpost in caustic. Probably not a great idea for a carbon frame.
Seatpost in vice - Twist frame
I've had this happen on two different bikes - I've now learnt my lesson.
First time it seemed that Dettol Multipurpose cleaner (green bottle) and a long pole worked for me.
Second time I tried everything including coke. In the end it was seat off, spanner through the holes and the work stand as a lever.
Neither caused any visible damage and the bike carried on their lives in peace.
Wish I had a vice!
Seatpost in vice – Twist frame
If this worked for you, then great. But your seatpost wasn't truly seized...it was just stuck.
Mine was clamped into a big-assed vice, with me and the bike shop chap twisting the frame until it was either going to release, or snap. At this point, we decided that twisting wasn't going to get this one out. And this was after days and days of soaking in various forms of cleaners too!
I'd have been vaguely interested to see if the seatpost man could have got mine out (not interested enough to pay the 2x price it would have cost me over the chap who cut it out though!) and I'd have loved to know what he'd have done too, but in the end, I was just relieved to have it chopped out and working again.
Seatpost in vice and twist is not what I would be doing on a carbon frame. I'd be wary you don't snap that carbon doing that.
