The Thomson Masterpiece shares all of the same great features as the Elite model but instead weights approximately 40 grams less. This weight reduction was achieved by machining the seatpost all over, including the oval inner diameter. Thomson were able to hold closer tolerances with machining than by extrusion alone. Despite this significant weight reduction it still maintains the strength and durability expected from a Thomson Seatpost. Machining all over on 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 aluminum. 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 other branded seatposts they tested, every one of them, resulted in a catastrophic failure of the seat and clamp components, with pieces of the tube and head flying off in all directions. This type of failure would dump the rider so Thomson designed a seatpin that 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 clamp at about 250 foot-lbs of torque, all other branded posts they tested flew apart at less than 150 foot-lbs of torque. Under severe impact the Thomson seatpost would bend slightly and allow the rider to come to a safe stop or finish the ride. The designs and materials have passed extensive life and ultimate strength tests and every production lot of seatposts will have ultimate strength and fatigue tests performed. Their on going testing program ensures that every production lot of seatposts meets Thomson's standards.

Adjustments can be made to the tilt of the seat without moving the seat forwards or backward, with infinite tilt adjustment from minus 5° to plus 29°. Very low profile clamps result in zero seat interference, with the swivel nuts located down between the seat rails. All Thomson seatposts also have all parts captive and can easily be attached to a seat without disassembly.
