Carbon parts keep on coming down in price, and with them comes confusion.

One point of head scratching is grease on a carbon seattpost. No need for it, and in some cases it can cause complicated problems. Assuming the seattube is honed and deburred the post should just slide right in, relatively free even without grease. Since the carbon doesn’t corrode, the non-metallic post won’t seize to the seattube like a dry steel, aluminum or ti post may. And keeping it grease-free should help prevent the post from slipping, allowing you to use less pressure on that binder bolt and prevent crushing the delicate carbon.

Beyond that, you don’t want that post swelling up with grease and really getting lodged in there. Thats right, certain posts will absorb certain lubricants, making them bloated enough to get seriously stuck in a seattube. Grease can actually make a carbon post get stuck, rather than the other way around. Nine times out of ten this doesn’t seem to happen… But you don’t want to be number 10. Personally, I’ve avoided pulling the lucky number… You?
