A lot of road bikes come spec d with aluminium options until you reach around the.
Carbon fiber seatpost in aluminum frame.
Remember zinc carbon.
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.
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.
An anti slip compound can prevent damage caused as.
A galvanic reaction occurs between the two different materials and this acts to eventually bond the post to the frame.
This is also true when installing a carbon post into a steel or aluminum frame.
When a seat post is fitted an anti slip compound should be applied to prevent loosening of the seatpost.
With a steel aluminum or magnesium frame spray oil or better yet frame saver into the seat tube to arrest the corrosion process.
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.
A carbon seatpost is lighter and promotes comfort seatposts are generally constructed from aluminium or carbon.
