I need your advice. My Easton EC70 carbon post seems to have seized to the seat tube of my Dean Ti. I can seem to budge it - even with a mallet. I think there is an aluminum sleeve in the seat tube.
Anyone experienced this before? What can I do to loosen the post? Would WD-40 work? Help!
It happened to a buddy of mine, but with a cheaper post and frame. After some serious effort he took it to a shop and had them do it.
Anyway, I'll tell you what a maintenance book says to do:
1) Remove seatpost binding bolt (obviously!)
2) Squirt penetrating oil all around the post so it will seap into the tube. If you're serious about it, you should also remove the bottom bracket and squit oil in from that end. Let it sit overnight.
3) Next day, stand over the post and apply twisting force to the saddle.
4) If step three doesn't do it, you must sacrifice the post.
5) remove saddle, clamps, etc. Put the post in a vice (thus ruining the post forever). Apply twisting force to the frame around the post, grabbing the frame from the extreme ends around the post - and realizing you can possible even bend the frame (but It's a Ti frame, they're very resilient). You should hear a loud "pop" if it releases.
6) if THAT fails, go to a machine shop. It can only be reamed out .. $$. I guess if it's a Ti frame it's worth doing that.
