That's a wonderful solution. The DI2 battery probably had something to do with the excessive corrosion. I've heard of Gallium being poured into the works and dissolving the aluminum post. I just left the stuck seatpost in when I restored, restromodded my steel classic and powder coated the whole frame. New decals were printed from the scanned originals. It fits me because I knew something back when I was 19, 45 years ago. Bought it face to face from Dave Moulton in the early years of his career. Got the handwritten invoice!
I have never seen a seatpost that had to be removed with a hydraulic press before. That's wild. I'd definitely be replacing that one with a carbon fiber seatpost.
I have a bike with same issue. I was thinking this video can help me to remove it, and now it is obviously conceive me to just leave it, and it's in the correct position anyway.
Sometimes you can get them out if their not to corroded by flipping the bike upside down & through a bottle cage bolt squirt a nice amount of 'Plus Gas' or another penertrating oil. Leave it to soak for a few days & give it tap in all directions with a hammer then give it a good twist & pull. Hope that may help.👍
@@NorfolkCycleWorkshop Sure i will try it. I just got a pulling hammer and i will try it first, to put in lots of WD-40 first and the pulling hammer should possible to do it. If not then i will try your method.
Give 'Plus Gas' or 'Penetranting fluid' by WD40 specialist range a go. They are miles better than regular wd40 that doesn't really do much apart from remove water.
@@NorfolkCycleWorkshop Ok i will try to find specialist range of WD40 a try. Regular 40 not really help, although i am sure i have plenty of gap that these fulid can reach deep inside. I got this frame brand new just 1 year age, it's renold 520 steel and I put on an aluminum seat post. Cannot belive it can just lock in with one year time.
