Well, I've finally encountered one I couldn't crack. Aluminum alloy seatpost stuck in an older Aegis
carbon frame. Looks like there's a steel insert surrounding the post, 'cause I can see some rust.
Usually, if after trying various brands of "rust-busters" and WD-40 with no success, I take out the
propane torch and heat the post, let it cool, and out it comes. I've reasoned that simply heating
and therefore "expanding" the post, only to let it cool again and contract, would buy me just enough
"space." Combine that with differing expansion coefficients and rates, dissimilar metals, etc.,
etc., and you "break" the bond. I'm no engineer, but it has never failed me before. Well, not this
time, even after trying all of the above repeatedly. LAY YOUR BEST RECIPE ON ME! Thanks, Mike
