The Thomson seatposts are what you get when you fire the bean counters and let a group of engineers loose on a bike component.  100% Made in the USA to exacting tolerances, and CNC’d so there is no excess material where it’s not needed, yet able to disgrace all their competitors in ultimate strength and fatigue tests.  In short you are looking at perfection.

Features and Specifications: 

• Over 40% stronger in ultimate strength tests than the strongest production seatposts on the market.
• Over double the fatigue life of any other production models tested. The tube and head of the Thomson seatpost aremachined from a 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 lower weights.
• Lightweight -  "Natural ellipse bore inside the tube for optimum strength to weight ratio". Which is Engineer-speak for front and back walls of the seatpost being thicker than the sides.  The stresses a rider places on his seat post are fore and aft, not left and right.  By removing material from the internal sides of the seatpost, but concentrating the material where its needed on the front and back walls of the post saves 30 to 40 grams of weight depending on length.
• Easy on seats - the generous length of the rail clamps allow a seat to survive heavy impact loads without bending rails.
• Every component of the Thomson seatpost is 100 percent American made. This includes all fasteners and forgings.
• Infinite tilt adjustment from minus 5° to plus 29° - no more having to accept the indexed positions of other seatpost clamps with teeth or knurled surfaces, and a tilt range that will cater to more frames that have slack seat tube angles.
• Very low profile clamps - no seat interference - swivel nuts aredown between the seat rails.
• Adjustments can be made to the tilt of the seat without moving the seat forwards or backwards.
• Length: 410mm 
• Weight:  Approx 190 grams
