The thread about seized seatposts with carbon and alloy and my own experience with alloy in my c456 seizing up has me thinking…
I want to add a Reverb to my Carbon 456, but what experiences have people had with galvanic corrosion (or whatever you like to call it), if any?
Thing is with my standard seatpost it’s getting shifted up and down a fair bit during rides and that I think may be rubbing off the carbon paste I apply, and that could be why the corrosion occurs. Someone argued in another post that the paste itself doesn’t help when shifting post all the time because the grit like friction stuff in it may be stripping surfaces allowing the bonding to occur more easily. Perhaps.
With a Reverb I’m not moving the post at all, so as long as there’s carbon paste on it and given the coating of paint also which is less likely to wear away due to movement, it’s less likely to bond?
What I don’t want is to leave it in and it’s fine for a year and then I need to pump up the air valve for some reason (as my Reverb on other bike sometimes needs), only to find the post has utterly bonded with the frame. Cutting a Reverb out is expensive and going to be tricky with the internals involved, plus it’s at pressure!
