The EA90 post is seized on my Blur, and whilst I don't move it often, the pollished allow crown is coming unbonded from the shaft, so I can't lever it loose with the saddle or clamp the crown up in a vice.
What's the best method? Upside down and penetrating oil in through the BB?
Ta!
If you're resigned to losign the post then I'd try a pair of Mole Grips around the shaft and use those to try and rotate it.
also, you might be better to take the seatclamp out the way and make a 'cup' of plasticine around the top of the post and the split and put the penetrating oil in there - it'll get into the gap far more than just randomly squirting it in from the other end.
Drill a hole through the post, but a bar through and use as leverage.
Mines stuck in my DMR, thats my excuse for being jey and I'm sticking to it!
