  • Infinite tilt adjustment from minus 5° and plus 29°
  • Super low profile clamps means no interference with the saddle as the swivel nuts are down between the seat rails.
  • Thomson designs and materials go through extensive life and ultimate strength tests. Our ongoing testing program ensures that every production lot of seat posts meets our seriously aerospace bike geek Thomson standards.
  • Impact absorbing clamps in the seat post spread and flex on impact to protect the saddle, rails, and rider. The result allows the seat to survive heavy impact loads without bending the rails.
