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.

Zero25 is a lightweight, universal seatpost with a twist: it's two seatposts in one. The two clever, reversible saddle rail clamps transform the post from zero saddle setback to 25mm setback. All that's needed is to flip the clamps from one side of the seatpost head to the other and the offset changes. No more problems with getting the wrong seatpost or needing another one when you change the type of saddle you use—it now takes 30 seconds to transform your seatpost. And, the best news is that, despite the double functionality, the Zero25 is even lighter than our previous seatpost. Zero25 Pro has an alloy pillar and is 350mm long.

Seatposts can easily be mistaken for a simple alloy or carbon tube, but it’s an essential part of your equipment. The amount of flex in a seatpost determines the comfort of your ride.
