I was using the dropper post for about a month and it was working absolutely flawlessly. I picked up a new dropper with a bit more travel and whenever I went to replace it, was dumbfounded to see the cosmetic damage on the lower part of the dropper. I'm not sure if this is some sort of residue from the carbon frame, or a friction element which scratched up the dropper - though it by no means is supposed to be like this. That being said, it works flawlessly, the reset switch does it's job, it feels silky smooth going up and down.
