Specialized Tarmac SL8 S-Works Di2: The Fastest Race Bike Ever
The Specialized Tarmac SL8 S-Works Di2 is a game-changer in the world of road racing. Combining aerodynamic efficiency, lightweight design, and unparalleled ride quality, this bike is the world’s fastest race bike. Developed over eight generations, the Tarmac SL8 has been engineered for ultimate speed, ensuring that no other bike on the market can match its performance on the road. Whether you're racing or riding for fun, the Tarmac SL8 is designed to help you push your limits and outperform the competition.
Key Benefits for Riders
Unrivaled Speed and Aerodynamics
The Tarmac SL8’s aerodynamic design plays a crucial role in its exceptional speed. It features a Speed Sniffer and optimized head tube geometry that reduce drag, allowing you to go faster with less effort. The frame’s narrow seat post helps guide air away from your legs, improving aerodynamics and reducing resistance. As a result, the Tarmac SL8 is 16.6 seconds faster over 40 km, 128 seconds faster over Milan San Remo, and 20 seconds faster on the Tourmalet climb than its predecessor.
Lightweight and Responsive
Weighing just 6.62 kg (14 lb, 9.5 oz), the Tarmac SL8 is the lightest race bike ever built. Constructed with S-Works FACT 12r Carbon, this bike offers a perfect balance of stiffness and compliance. With its Rider-First Engineered™ design, the Tarmac SL8 provides consistent performance and handling across all frame sizes. The result is a bike that feels like an extension of your body, responding to every pedal stroke with speed and precision.
Precision Shifting with Shimano Dura-Ace Di2
Equipped with the Shimano Dura-Ace R9270 Di2 groupset, the Tarmac SL8 offers smooth, reliable shifting at the touch of a button. The Di2 system ensures fast and precise shifts, even under load, and with the addition of the 4iiii Precision 3+ Pro dual-sided powermeter, you can track your power output and optimize your performance on every ride. The hydraulic disc brakes provide excellent stopping power, allowing you to control your speed with confidence in any condition.
Comfortable, Stable Ride
The Tarmac SL8’s geometry is designed to provide an aggressive yet comfortable riding position. The S-Works Power with Mirror saddle enhances comfort for long rides, while the Roval Rapide CLX II wheels, paired with tubeless tires, offer superior traction and a smooth ride. With Future Shock 3.0 suspension, you can conquer rough roads while maintaining stability and comfort. Whether you're climbing, descending, or cruising on the flats, the Tarmac SL8 delivers exceptional control and responsiveness.
Advanced Technology for the Modern Rider
The MasterMind Turbo Control Unit (TCU) provides real-time information about your ride, including battery status and power levels. It seamlessly integrates with the Specialized app, giving you access to advanced tuning features, range optimization tools, and on-ride diagnostics. With Turbo System Lock, the Tarmac SL8 also ensures your bike is safe, allowing you to disable the motor and activate an alarm when the bike is unattended.
