Thomson - Elite Seatpost Inline Black 31.6 x 367

The Thomson Elite seatpost is over 40% stronger on ultimate strength tests than the strongest production seatposts on the market.

The Elite 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.

Certified to: EN 14766 2006 MTB and DIN CERTCO: 2006 MTB

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.

We 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 our grip 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.

The 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.

The 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. Our 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.
