• Hi all!
    Before you get into any drastic measures, try using Plusgas! I had previously used a bike stand and about 25 minutes of levering the whole bike unsuccessfully. I sprayed plusgas in around the seatpost, let it soak in for an hour, then turned the bike upside down and sprayed it in the seat tube mounting holes and left it for an hour. It then came unstuck by hand.

    I still have half a can if anyone in S London wants to try it

  • Sigh. Might be hitting you up for that plusgas shortly. Just tried to replace my seatpost clamp only to find my seatpost has seized in my frame. I have the added fun/expense of having a di2 battery in the seatpost so trying to avoid pouring caustic soda into seat tube.

  • Do you know if Plusgas work for aluminium stuck in steel or is it only good for steel on steel? Might need to buy a can
