The Thomson Masterpiece Seatpost is not for everyone. At Thomson they wanted to create the best seatpost possible without regard to cost.
The serious cyclist will want to own the Thomson Masterpiece Seatpost. 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. Thomson accomplished this weight reduction by machining the seatpost all over - including the oval inner diameter. 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 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.
Natural ellipse bore inside tube for optimum strength to weight ratio. They have a long 1.614 inch (41mm) seat rail grip length. This helps prevent seat rail bending from impact loads. The Thomson seatpost design incorporates a bending fuse to prevent catastrophic failure. The Thomson seatpost has a clamp, head, and upper tube strong enough to withstand 350 foot-lbs of torque. The tube will start to yield and bend at the seat tube clamp at about 250 foot-lbs of torque.
Every component of the Thomson seatpost is 100 percent American made. This includes all fasteners and forgings.
The Thomson seatpost has all parts captive and can easily be attached to a seat without disassembly.
Infinite tilt adjustment minus 5° and plus 29°.
Very low profile clamps - no seat interference - swivel nuts are down between the seat rails.
The designs and materials have passed extensive life and ultimate strength tests.
Every production lot of seatposts will have ultimate strength and fatigue tests performed. Our on going testing program insures that every production lot of seatposts meets Thomson standards.
Impact absorbing clamps - clamps, head, and assembly will spread and flex on impact to protect seat, rails, seatpost and rider.
Adjustments can be made to the tilt of the seat without moving the seat forwards or backwards.
Easy on seats - allows seat to survive heavy impact loads without bending rails.
Manufacturer recommended weight limit of 91kg/200lbs
