Over 40% stronger on ultimate strength test than the strongest production seatposts on the market * The tube and head of the Thomson seatpost are integral-machined from one single piece of high strength 7000 series aluminum * Natural ellipse bore inside tube for optimum strength to weight ratio * Long 1.614 inch (41mm) seat rail grip length, this helps prevent seat rail bending from impact loads * Clamp, head, and upper tube strong enough to withstand 350 foot-lbs of torque, under severe impact the Thomson seatpost would bend slightly and allows the rider to come to a safe stop or finish the ride
