The Thomson Elite seatpost from Thomson is exceptionally strong, with a 40% higher ultimate strength than other seatposts on the market. It also has double the fatigue life of other production models. The seatpost is made from high strength 7000 series Aluminium, with the tube and head machined from one piece for maximum strength and minimum weight. It is certified to EN 14766 2006 MTB and DIN CERTCO: 2006 MTB standards. Weighing approximately 201g for road bikes and 228g for mountain bikes, the Thomson Elite seatpost is incredibly lightweight. The natural ellipse bore inside the tube ensures an ideal strength-to-weight ratio. With a long 1.614 inch (41mm) seat rail grip length, this seatpost prevents seat rail bending from impact loads. Most other seatposts have grip lengths at least 0.5 inch shorter. The design of the Thomson seatpost includes a bending fuse to prevent catastrophic failure. In tests, other seatposts failed catastrophically, with pieces flying off in all directions. The Thomson seatpost has a clamp, head, and upper tube that can withstand 350 foot-lbs of torque. The tube will start to bend at the seat tube clamp at about 250 foot-lbs of torque. In the event of a severe impact, the Thomson seatpost will bend slightly, allowing the rider to come to a safe stop or finish the ride. It is easy to attach the Thomson seatpost to a seat without disassembly, as all parts are captive. The seatpost also offers infinite tilt adjustment from minus 5° to plus 29°. The low profile clamps mean there is no interference with the seat, as the swivel nuts are positioned between the seat rails. Thomson has extensively tested the designs and materials of their seatposts for life and ultimate strength. Their ongoing testing program ensures that every production lot meets their high standards. The impact absorbing clamps in the seatpost spread and flex on impact to protect the seat, rails, and rider. The seats can withstand heavy impact loads without bending the rails.
