Thomson Masterpiece Seatpost

Think of the Masterpiece as an Elite post on a diet. It weights approximately 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. The weight reduction was accomplished by taking an Elite seatpost and machining and relieving material everywhere possible, including the oval inner diameter. With all the excess material being removed there is no compromise in durability. The post still retains all the strength and stiffness you come to expect from a Thompson product, just many grams lighter.

In terms of constructions, the shaft itself is made from elliptically extruded, machined and anodized 7000 series alloy. The clamp plates are forged and anodized. The plates are 41mm long so they prevent seat rail bending from impact loads. Bolts are steel while the washer and nuts are brass which help inhibited rust and corrosion.

Simplicity is profound and in this case it comes in not just the overall design of the Masterpiece, but the cosmetics as well. The shaft has a micro ribbed texture and etched Thomson graphics on each side of the post. A true beauty.

    This is simply the best seatpost: super-light, infinitely adjustable, stays adjusted once set, large rail-clamp surface.

    Pros light, adjustable, strong

    Cons none

    I have been using the Thomson elite seatpost for two years now and I’m delight with it. The masterpiece must be a dream! If it only can in a 27.0 I will buy it in a heartbeat.
