How to Choose the Right Bike Seatpost
Choose your seatpost based on the type of riding you do and your bike’s fit. Mountain riders may want dropper or rigid posts for rough terrain, while gravel and road riders often prefer lighter options like carbon fiber. Make sure the post fits your frame and supports your saddle position.

About Thomson
Thomson began in Macon, Georgia, as a precision aerospace machine shop. When founder Ronnie Thomson created the first Elite seatpost for his daughter, a competitive cyclist, it changed the industry. Today, Bike Thomson produces high-performance components built to meet real-world demands with the same aerospace quality. Every seatpost is machined in the USA, tested for strength and fatigue, and designed to deliver years of reliable riding.
