Seatposts

Thomson's Elite Seatpost is perhaps one of the most recognizable bicycle components in the world and it has earned its reputation as a super-strong, light and reliable beauty. With roots in the aerospace industry, Thomson builds the post with a tough and light 7000-series aluminum body, an elliptical extrusion that adds strength and stiffness, and a head and seat clamp forged and machined from a block of aluminum to eliminate any possible weak areas. Plus, its simple-to-use 2-bolt seat clamp allows speedy, infinite and secure seat angle adjustment from minus 5 degrees to plus 29 degrees. Upgrade your favorite ride to a Thomson seatpost and start riding in style.

On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored seatpost color is available on the Zipp Service Course Seatpost.
