About Thomson

In a world of carbon fiber this-and-that Thomson has staked their reputation on the quality of their CNC'd aluminum stems and seatposts. While it might be hard to believe, Thomson seatposts and Thomson stems are every bit as light as what you might find in carbon. But Thomson components cost half of carbon, and possess a bulletproof toughness impossible to find in carbon.
