The Masterpiece is over 40% stronger on ultimate strength tests than the strongest production seatposts on the market. Masterpiece posts weigh approximately 40 grams less than the same size Elite post. This weight reduction is accomplished while maintaining the strength and durability expected of a Thomson seatpost. 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 over an already beautiful design makes the Masterpiece Seatpost a work of art.
Certified to: EN 14766 2006 MTB.
The tube and head of the Thomson Masterpiece seatpost is integral-machined from one piece of high strength 7000 series aluminum. The head is not pressed or bonded in. This allows for superior strength and minimum weight.
We have a long 1.614 inch (41 mm) seat rail grip length. This helps prevent seat rail bending from impact loads. Most other seatposts have grip lengths of at least .500 inches shorter than our grip length.
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 flew 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.
The Masterpiece seatpost has all parts captive and can easily be attached to a seat without dis-assembly.
Infinite tilt adjustment minus 5° and plus 29°.
Very low profile clamps means no seat interference as the swivel nuts are down between the seat rails.
The designs and materials have passed extensive life and ultimate strength tests. Our ongoing testing program ensures that every production lot of seatposts meets Thomson standards.
