Carbon Seatpost preparation
How thoroughly do I need to remove grease from the seat tube, etc before installing a carbon seatpost in place of an alloy post?
Aluminum frame, if that matters.
Thanks

Doesn't have to be sterile clean, just enough that when running your finger in the ST it comes out clean. Make sure to apply new grease or carbon paste.

Agree with Crankycrank, and while I have not seen it with bikes in industry we have had greases disagree with some carbon epoxies resins.

Though assembly paste can scratch finishes, so I'd only use if you need it.
