Bicycle Seatposts

The seatpost is the tube that extends from your frame to your saddle. Seatposts are typically constructed of aluminum or carbon fiber. Seat posts are available in rigid models, suspension models, as well as height adjustment models. Clamp design will differ from brand to brand: for example, a Thomson seatpost clamp design will not be identical to a Ritchey seatpost clamp design. However, both clamps do the same job. Bike.com has all the top seatpost brands, so we are sure to have what you are shopping for.
