Whats the deal with dropper post maintenance on gravel bikes? Are they really as finicky as everyone makes them out to be? Ive heard some guys saying you need to service them every few hundred miles or risk them seizing up, while others claim theyre basically set-it-and-forget-it. Whats the reality? Should I be worried about grit and grime accumulating in the post, and if so, how do I clean it out without damaging the internals? Are there any specific products or techniques that work better than others? And what about lubrication - do I need to re-lube the post regularly, or is that just a myth perpetuated by the lube manufacturers?
