SPECIALIZED S-WORKS TARMAC SL8 SRAM RED

The Specialized S-Works Tarmac SL8 is the ultimate expression of the modern road bike: a project that unites aerodynamics, lightness, and rigidity into a single platform designed to win on every terrain. After eight generations of development, the Tarmac SL8 represents the fastest model ever produced by Specialized, engineered to deliver absolute performance both on climbs and on flat terrain, without compromise on ride quality.

The concept behind the Tarmac SL8 is real-world speed, achieved through the perfect integration of aerodynamics, weight, and power transfer. Thanks to advanced simulations and data collected on the road, Specialized has developed a frame capable of being faster on any route: from long flats to the great classics, to the most challenging climbs.

The aerodynamics have been completely revised, with a redesigned front section to reduce air resistance. The new design of the steering tube and fork improves aerodynamic flow, while the slim, profiled seatpost optimizes air penetration in the leg area, increasing efficiency at high speeds.

The S-Works FACT 12r frame weighs only 685 grams and derives directly from the experience gained with the Aethos. The tube shapes have been optimized to offer maximum stiffness where needed, eliminating superfluous material and improving the stiffness-to-weight ratio by 33% compared to the previous generation. At the same time, the bike better filters vibrations, ensuring a more comfortable and stable ride even at high speeds.

The racing geometry, tested in World Tour competitions, ensures precision and responsiveness, while compatibility with tires up to 32 mm allows for improved comfort, grip, and safety on every type of asphalt.

This S-Works version represents the top-of-the-range specification, with a SRAM RED AXS electronic groupset with power meter, Roval Rapide CLX II tubeless-ready carbon wheels, and an integrated Roval Rapide cockpit. A configuration designed for those seeking maximum performance without compromise.

Tip: to receive the bike ready to use, you can add the “Bike assembled and adjusted by Cicli Drigani technicians” option to your cart for 59€. With this service, the bike will arrive assembled, adjusted, and ready to ride. Without this option, the bike will be delivered in the manufacturer's original packaging and will require some technical operations before it can be used safely.
