The Masterpiece is Thomsons ultimate seatpost.
It combines incredibly light weight with the characteristic strength and function of a Thomson. Masterpiece seatposts weigh approximately 40 grams less than an Elite seatpost of the same size, while maintaining high strength and durability. Thomson accomplishes this weight reduction by machining the seatpost all over; including the oval inner diameter. We are able to hold closer tolerances by machining than by extrusion alone. Machining all over an already beautiful design makes the Masterpiece Seatpost a work of art.
The tube and head of the Thomson Masterpiece seatpost is integral-machined from one single piece of high strength 7000 series aluminium. The head is not pressed or bonded in. This allows for superior strength and minimum weight, allowing higher strength at low weights.
The Thomson Masterpiece seatpost design incorporates a bending fuse to prevent catastrophic failure. All competitive seatposts we tested failed catastrophically with the seat and clamp components, and sometimes pieces of the tube and head flying off in all directions.The Thomson Masterpiece seatpost has a clamp, head, and upper tube strong enough to withstand 325 foot-lbs of torque. The tube will start to yield and bend at the seat tube clamp at about 230 foot-lbs of torque. Under severe impact the Thomson Masterpiece seatpost will bend slightly but allow the rider to come to a stop or continue the ride.
