Seized Seapost

Hi Guys

I have just tried to lift my seat post up a bit to try a new position as I think the current position could be affecting my pedalling stroke and I can't shift it for the life of me.

Its an Oltre Full Carbon Aero seat post so I don't have the luxury of being able to twist and pull, it has to be pulled directly up.

I have tried to heat the seat post/frame with a kettle and WD40 around the top where the clamp is (I moved the clamp up)

As this is a carbon bike would heating the frame with a hairdryer work?

Advice would be appreciated as I have been quoted £80 for it to be removed and would rather avoid this incase I have to also buy a new seat post.

Thanks

    Try something like plusgas.

    Is that not the same as WD40?

    No. Plusgas is a penetrating lubricant. WD40 is a moisture dispersant.

    Thanks, I will pick that up and give it a try.

    Is heating the frame where the seat post goes down with a hairdryer a bad/good idea? I don't want to damage the frame

    The seaport can be replaced but the frame is a different kettle of fish.

    If it still wont budge try taking off the saddle and putting something with a similar diameter as the saddle rails in its place (a couple of screwdriver shafts or something). You will then have something which can be gently tapped upwards with a rubber mallet to get it moving.

    Try loctite freeze spray

    then heat with a hairdryer a few times.

    The heat/cold should free it

    Problem solved, thanks. Put my aerobat through the top of the post and with a mix of wd40 and hot water I managed to release it.

    Relieved as the position was causing me pain and struggling to push power through the pedals.
