This seatpost is a direct replacement option for design of the Tarmac SL7 frameset that was released for 2021. The S-Works grade FACT carbon construction has an aerodynamic, frame-specific build and has a convenient integrated rear facing compartment for Shimano's 1st gen e-Tube wiring Di2 junction set-up.

The post has a cylindrical aluminum head assembly that offers fore-aft adjustment with an easily accessed single-bolt system. Specialized offers this S-Works Tarmac Carbon Seatpost in a Zero offset and 20mm setback options, in both 300mm and 380mm lengths. Changing the setback and/or length for fit purposes is the primary reason this seatpost design is purchased.
