Specialized Tarmac SL8 Pro - Ultegra Di2: The Fastest Race Bike on the Road
The Specialized Tarmac SL8 Pro - Ultegra Di2 is the culmination of years of engineering, designed to be the fastest, lightest, and most aerodynamic race bike in the world. With a combination of cutting-edge technology, lightweight construction, and a focus on speed, this bike is built for the serious cyclist looking to push boundaries and dominate the racecourse.
Key Benefits for Riders
Unmatched Aerodynamics for Maximum Speed
We’ve engineered the Tarmac SL8 with aerodynamics at the forefront. The Speed Sniffer nose cone and the new sharp head tube design optimize airflow, delivering a significant reduction in drag. The narrowest, most aero seat post we've ever made ensures fast-moving, dirty air around the legs flows back more cleanly, making this the most aerodynamic road bike ever, surpassing even the Venge.
Beyond Gender: Designed for All Riders
With our Rider-First Engineering, the Tarmac SL8 caters to all riders, regardless of gender. While traditional bikes are often designed based on gender, we believe that rider size and style are what truly matter. The Tarmac SL8 offers the same race-winning advantages for everyone, ensuring a personalized, optimized ride.
Incredible Stiffness-to-Weight Ratio
The Tarmac SL8 has been fine-tuned for 33% more stiffness-to-weight than the SL7. The result? A stiffer ride at the pedals, more precision at the bars, and a 6% increase in compliance, making it comfortable to ride even on the roughest roads. With 32mm tire clearance and an adaptable geometry, this bike offers excellent handling and versatility for any terrain.
Lightweight Yet Aerodynamic
At just 7.16 kg (15 lb, 12.6 oz), the Tarmac SL8 frame is built to be ultra-lightweight while still achieving maximum aerodynamic efficiency. The frame is constructed with FACT 10r carbon, applying the latest learnings from the Aethos, resulting in a frame that is 15% lighter than the SL7. Despite the reduction in weight, the frame maintains its strength and stiffness, making it the perfect choice for the World Tour.
Performance Ready with Ultegra Di2
The Shimano Ultegra Di2 8100 series groupset offers lightning-fast electronic shifting, while the power meter ensures you’re always in control of your performance. Paired with the Roval Rapide CL II tubeless-ready wheels, you’ll experience smooth, precise handling and exceptional speed. The Roval Rapide Cockpit with integrated handlebars and stem further reduces weight while improving aerodynamics.
Why Choose the Specialized Tarmac SL8 Pro - Ultegra Di2?
If you're looking for the ultimate combination of aerodynamics, lightweight performance, and cutting-edge technology, the Specialized Tarmac SL8 Pro - Ultegra Di2 is the bike for you. With its ultra-responsive design, precision handling, and unparalleled speed, it's the perfect tool to help you achieve your best performance in any race or ride.
