Specialized S-Works Tarmac Carbon Seatpost

The S-Works Tarmac Seatpost for Specialized Tarmac SL7

The Specialized S-Works Tarmac carbon seatpost is compatible with the 2021 Tarmac SL7 road bike. A D-shaped cross-section makes it particularly aerodynamic, while the Di2 distributor from Shimano can be hidden on the inside. The S-Works Tarmac's screw-in clamp allows you to easily adjust both the saddle position horizontally as well as the saddle angle.

FACT™
FACT is an acronym for " Functional Advanced Composite Technology" and summarises all the know-how that Specialized has in the use of carbon fibre. It is a holistic approach, which primarily concerns the bike frames, but is found in many components such as handlebars, stems, saddles etc. The starting point is always the awareness for the needs of riders and the capability to fulfil them. Next, the selection of fibres, resins and fabric layers takes place; in this process the quality of the carbon and the arrangement of the fibre layers play an important role. It is important to find the right set-up for the project at hand and the intended location or rather the area of application. It is often necessary to differentiate from model to model at several points. In the final step, attention is paid to processing the material in a way that allows the desired advantages in terms of low weight, rigidity and stability to be achieved.
