Maintain Your Seatpost - One important and often-neglected maintenance task is seatpost lubrication. Left alone, steel and aluminum seatposts can actually freeze in steel and aluminum frames due to corrosion from water that seeps between the seatpost and frame on wet rides. To prevent this and keep the post moving freely, extract it about every two months (more frequently if you ride in wet conditions a lot) and apply a light coat of lube inside the seat tube on the frame (if you smear the lube on the seatpost, it'll get scraped off when you slide the post into the frame). Please note that most manufacturers do not recommend greasing carbon frames or carbon seatposts. Please ask if you have any questions about your bicycle.
