Thomson Masterpiece Seatpost
Every bike you own should have a Thomson post on it. The Masterpiece keeps all of the burliness of the classic Thomson post and shaves grams, because a lighter seatpost will make you faster right? There are lighter options but I've broken one of those mid-crit and tried to finish the race. I will say this: there are a few places where you should not aim a jagged piece of carbon fiber. After that experience, I've sworn off of the featherweight junk and onto Thomson. The fact that they've made a lightweight post is certainly a nice extra.
