The Specialized Tarmac SL8 Pro Ultegra Di2 is a revolutionary performance road bike that combines aerodynamics, lightweight design, and ride quality like never before.

Key Benefits for Riders
Unmatched Speed and Aerodynamics
The Tarmac SL8 is built for speed, combining aerodynamics, lightweight construction, and compliance to deliver unparalleled performance. The frame’s optimized geometry, including a Speed Sniffer and narrow seat post, ensures maximum aerodynamic efficiency. This makes the Tarmac SL8 16.6 seconds faster over 40 km, 128 seconds faster over Milan San Remo, and 20 seconds faster on the Tourmalet climb compared to previous models.
Lightweight Design for Ultimate Performance
Weighing just 7.16 kg (15 lb, 12.6 oz), the Tarmac SL8 is incredibly lightweight without sacrificing strength or stiffness. The FACT 10r Carbon frame and Rider First Engineered™ design provide the perfect balance of stiffness and compliance, ensuring that every pedal stroke delivers maximum power to the wheels. The bike’s frame is designed to provide superior handling and responsive performance, making it the ideal choice for competitive cyclists.
Precise Shifting with Shimano Ultegra Di2
The Shimano Ultegra Di2 groupset offers electronic shifting for smooth, fast, and precise gear changes. Paired with the 4iiii Precision 3+ Power Meter, it delivers real-time power data, helping you optimize your performance. The hydraulic disc brakes provide superior stopping power, ensuring you can brake confidently at high speeds, even in tough conditions.
Comfortable and Stable Ride
With a focus on comfort and stability, the Tarmac SL8 features a Roval Rapide CL II wheelset with tubeless-ready tires and a S-Works Power Pro with Mirror saddle, designed to reduce discomfort during long rides. The Future Shock 3.0 suspension ensures that you stay comfortable on rough terrain, while the bike’s frame geometry offers a perfect balance of aggressive performance and stability.
Advanced Technology for Enhanced Performance
The MasterMind Turbo Control Unit (TCU) allows you to monitor your ride in real-time, displaying battery levels, power modes, and performance data. The TCU integrates seamlessly with the Specialized app, giving you access to advanced features such as range optimization, real-time diagnostics, and power tuning. With the Turbo System Lock, you can secure your bike by disabling the motor and activating the motion sensor alarm when it’s not in use.
