Another vote for soaking with liquid penetrant. You should consider removing the water bottle screws from the seat tube and using them as a way to add penetrant from the bottom of the bike. If your Trek does not have water bottle mounts on the seat tube, you could remove the bottom bracket and access the bottom of the seat tube that way. Depending upon what type of seat post you have installed, it may even be possible to "fill" the seat tube with enough penetrant to really get a good soaking. Once you have added the penetrant from the bottom, store the bike upside down.
If you should decide to sacrifice the seat post to get it out, consider using it to your advantage before cutting it off. I once had a stuck seat post in a tandem. I turned the bike upside down, clamped the post in a bench vise, then used the twisting action of turning the bike on post to eventually free it. I had "PLENTY" of leverage with the frame and had the post clamped down so tight in the bench vise that it was almost squished flat! My stuck seat post eventually broke free, but it was a very noisy operation. Good luck! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
