The road bike seatpost is a device that holds the saddle to the frame of the bike.

Features of a road bike seat post:

road bike seatpost generally consists of a tube to which a saddle carriage is attached. The seat tube is used to vary the height of the saddle relative to the road bike crankset, it also allows the orientation of the saddle to be adjusted relative to the road bike stem. The saddle carriage is used to adjust the distance between the saddle and the road bike handlebar, this adjustment is also called saddle setback; the saddle carriage is also intended to orient the saddle relative to the horizontal.

Some road bike frame manufacturers have chosen to develop their own road bike seatpost whose shape is not round, it is specific to the shape of the vertical tube of the frame, this is the case with certain Look cycle models, Time, BMC, ....

How to choose your road bike seat post ?

Here are the criteria allowing you to identify the road bike seatpost corresponding to your needs.

For road bike frame models which are designed for a tube that is not in round shape, you will have no other choice to use the road bike seatpost corresponding to the brand and model of your road bike.

On the other hand, if the frame of your road bike is designed for a round road bike seatpost then the choice will be wider. In this case, you will need to determine:

  • the diameter of the tube of the road bike seatpost 
  • tube length
  • the material of the road bike seat post
  • the weight

road bike seatpost can be made of aluminum or of carbon that is lighter and more rigid than aluminum, unfortunately carbon is not recyclable.

When fitting the seatpost of your road bike, we recommend that you apply grease between the tube and the frame of the road bike in order to prevent it from locking after a few months.

What are the brands of road bike seatpost:

Some brands are specialized in the design and manufacture of road bike seatposts, such as FSA, Thomson, Dedacciai, BBB, Velo Orange seatposts or 4ZA which offer quality road bike seatposts, in carbon or aluminum of all types and sizes.
