The Thomson - Masterpiece Seatpost Setback Black 27.2 x 240 is a high-quality seatpost from Thomson. It is stronger than most other seatposts on the market, with over 40% more ultimate strength. Despite its strength, it is also lightweight, weighing approximately 40g less than the same size Elite post. This weight reduction is achieved through careful machining of the seatpost, including the oval inner diameter. This machining process allows for closer tolerances and greater strength.The Thomson Masterpiece seatpost is certified to meet the standards of EN 14766 2006 MTB. It is made from a single piece of high strength 7000 series aluminium, which ensures superior strength and minimum weight. The head of the seatpost is not pressed or bonded in, further enhancing its strength.One notable feature of the Thomson Masterpiece seatpost is its long seat rail grip length of 1.614 inches (41 mm). This prevents seat rail bending from impact loads, which is a common issue with other seatposts. Most other seatposts have grip lengths at least 0.5 inches shorter than the Thomson Masterpiece.Another important feature of the Thomson Masterpiece seatpost is its bending fuse design, which prevents catastrophic failure. When tested against competitive seatposts, the Thomson Masterpiece outperformed them all, with no catastrophic failures. The seat and clamp components remained intact and there were no instances of pieces flying off.The Thomson Masterpiece seatpost is also exceptionally strong. It can withstand up to 325 foot-lbs of torque, thanks to its strong clamp, head, and upper tube. The tube may start to yield and bend at the seat tube clamp at about 230 foot-lbs of torque. Even under severe impact, the Thomson Masterpiece seatpost will only bend slightly, allowing the rider to come to a stop or continue the ride.Installing the Thomson Masterpiece seatpost is easy, as all parts are captive and can be attached to a seat without disassembly. The seatpost also offers infinite tilt adjustment, ranging from -5° to +29°.The clamps of the Thomson Masterpiece seatpost have a very low profile, which means there is no interference with the seat. The swivel nuts are located between the seat rails, ensuring a clean and streamlined appearance.Rest assured, the Thomson Masterpiece seatpost has undergone extensive testing to ensure its durability. Its design and materials have passed life and ultimate strength tests, and Thomson continues to test every production lot to meet their high standards.
