Thomson Elite Setback Seatpost Black

The Thomson Elite Setback Seatpost has double the fatigue life of any other production models tested. The tube and head of the Thomson seatpost are integral-machined from one piece of high strength 7000 series Aluminium. The head is not pressed or bonded in. This allows for superior strength and minimum weight.It’s incredibly lightweight, approximately 201g (250mm length) for road bikes and 228g (330mm length) for mountain bikes. The natural ellipse bore inside tube creates an optimum strength-to-weight ratio.These seatposts have a long 1.614 inch (41mm) seat rail grip length. This helps prevent seat rail bending from impact loads. Most other seatposts have grip lengths of at least 0.5 inch shorter than Thomson'sgrip length.The Thomson seatpost design incorporates a bending fuse to prevent catastrophic failure. All competitive seatposts tested, failed catastrophically with the seat and clamp components, sometimes pieces of the tube and head flew off in all directions.This Thomson seatpost 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 tube clamp at about 250 foot-lbs of torque. Under severe impact the Thomson seatpost will bend slightly and allow the rider to come to a safe stop or finish the ride.Thomson Elite Setback Seatpost FeaturesThe Thomson seatpost has all parts captive and can easily be attached to a seat without dis-assembly.Infinite tilt adjustment minus 5° and plus 29°.Very low profile clamps means no seat interference as the swivel nuts are down between the seat rails.The designs and materials have passed extensive life and ultimate strength tests. Ongoing testing program ensures that every production lot of seatposts meets Thomson standards.Impact absorbing clamps in the seatpost will spread and flex on impact to protect seat, rails, and rider. The seats survive heavy impact loads without bending the rails.Thomson Elite Setback Seatpost Specifications7000 series Aluminium.41mm Seat Rail grip length.Available in 250mm, 330mm, 367mm and 410mm lengths.Available in all seatpost sizes.-5° to +29° Tilt adjustment.228g weight (330mm length).Certified to: EN 14766 2006 MTB and DIN CERTCO: 2006 MTB
