Specialized S-Works Phenom Carbon Saddle

Item number: 78560

The Specialized S-Works Phenom Carbon saddle - light, stiff, race capable

The S-Works Phenom saddle from Specialized for road and off-road racing impresses with its particularly low weight and high stiffness. It has been equipped with a saddle shell made of carefully selected and expertly processed carbon fibre (FACT™ Technology) and oversized carbon struts. Due to the Body Geometry Design, including a narrow cut-out in the middle, the arterial blood circulation in the sensitive sit bone area is guaranteed at all times. The saddle has been padded with medium padding to achieve an optimal balance between damping and feedback even during longer rides. Threads are integrated into the saddle shell to allow the attachment of Specialized SWAT™ accessories.

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.

Body Geometry
Body Geometry products from Specialized address the contact points between rider and bike. They are designed in collaboration with doctors, scientists and athletes to increase performance, improve riding comfort and prevent injuries, taking into account medical-anatomical aspects. Body Geometry features are found on Specialized saddles (padding, shaping), shoes (outsole, footbed, etc.) as well as gloves (padding).
