Subject: grease vs. anti-seize Posted by: Dennis K on August 19, 2006 at 17:16:38:

Message: A friend of mine asked me why we use grease on the seatpost when it slips even when the binder bolt is too tight (aluminum frame, aluminum post, low-end bike - fairly common problem). Thinking there are no stupid questions, I pondered before I answered him. Wouldn't it be better to use anti-seize? In fact, after some thought it seemed like anti-seize was preferred in a lot of applications where I have been using grease (threads on pedals, freewheels, and bottom brackets, quill stems, etc). Should I save the grease for applications where bearings are involved, and otherwise use anti-seize? It seems like anti-seize does better at fighting the bimetallic corrosion between aluminum and steel than any grease would.
