I’ve got a seatpost that is quite stuck on a road bike I recently bought. Using another seatpost, I can get some rotation, but so far I have not been able to get vertical movement to get it out eventually.
I made the construction in the picture using a bungee, but it does not seem te be providing enough force. Any clues what could help?
I have been using wd40 regularly to get some lubrication, frame is aluminium, seatpost as well
