Thomson Masterpiece Seatpost (Black) (31.6mm) (350mm) (0mm Offset) - SP-M107-BK
Thomson Masterpiece Seatpost (Black) (31.6mm) (350mm) (0mm Offset) - SP-M107-BK, The Masterpiece is Thomson's 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. Over 40% stronger on ultimate strength test 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 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 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. 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 .500 inch or more 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 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...
