Thomson Inline Seatpost

Over 40% stronger on ultimate strength test than the strongest production seatposts on the market.

Over double the fatigue life of any other production models we tested. The tube and head of the Thomson seatpost are 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.

Lightweight - approximately 188 grams (250 length) for road bikes and 228 grams (330 length) for mountain bikes. 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 brand-x seatposts have grip lengths of .500 inch or more shorter than our grip length.

Infinite tilt adjustment minus 5° and plus 29°.

Very low profile clamps - no seat interference - swivel nuts are down between the seat rails.

The designs and materials have passed extensive life and ultimate strength tests.
