Masterpiece posts weigh approx 40 grams less than the same size Elite model post. This weight reduction was accomplished while maintaining the strength and durability expected from a Thomson Seatpost.
Thomson accomplished this weight reduction by machining the seatpost all over--- including the oval inner diameter. We were able to hold closer tolerances by machining than by extrusion alone. Machining all over on an already beautiful design makes the Masterpiece Seatpost a work of art.
Over double the fatigue life of any other production models we tested. The tube and head of the Thomson seatpost are integral-machined from one single piece of high strength 7000 series aluminum. The head is not pressed or bonded in. This allows for superior strength and minimum weight, allowing higher strength at low weights.
