Carbon Fiber Seatpost In Aluminum Frame

An anti slip compound can prevent damage caused as.

Carbon fiber seatpost in aluminum frame.

I gave the seatpost a light coating and reinserted it. A carbon seatpost is lighter and promotes comfort seatposts are generally constructed from aluminium or carbon. When a seat post is fitted an anti slip compound should be applied to prevent loosening of the seatpost. I ve subsequently bought a pot of the carbon paste and whip the post out every 6 months or so for a quick wipe down and reapplication.

This is also true when installing a carbon post into a steel or aluminum frame. Re grease the post and the inside of the seat tube and then. The bike shop sent me a little sachet of carbon assembly paste to try. A galvanic reaction occurs between the two different materials and this acts to eventually bond the post to the frame.

When inserting an aluminum post into a carbon frame it is important to apply a barrier between the two surfaces. Given the potential for galvanic corrosion where carbon and aluminium are in contact in a wet environment a carbon seat post is probably a good idea in a full carbon frame. With a steel aluminum or magnesium frame spray oil or better yet frame saver into the seat tube to arrest the corrosion process.
