Specialized Tarmac SL8 Pro - Ultegra Di2

Discover the unmatched power of the Tarmac SL8 Pro with Shimano Ultegra Di2, the racing bike that redefines speed. With a revolutionary combination of advanced aerodynamics, lightness, and unparalleled ride quality, the Tarmac SL8 is more than just a bike: it's your key to dominating every road.

The Tarmac SL8 stands out with eight generations of development, emerging as the fastest racing bike in the world. Our Ride Science Team, through complex simulations and real-world data, has proven that this bike is unstoppable: -16.6 seconds over 40 km on flat terrain, 128 seconds faster on the Milano-Sanremo route, 20 seconds faster on the ascent of Tourmalet.

Extraordinary Aerodynamics and Lightness: Aerodynamics is our strength, making the Tarmac SL8 faster even than the Venge. With optimized frontal area and strategically positioned fork dropout, we achieve minimal aerodynamic drag. The aerodynamic seat post contributes to smooth airflow, ensuring superior performance.

Lightness is crucial, and with a frame weighing 685 grams, the Tarmac SL8 is 15% lighter than its predecessor SL7. The principles learned with the Aethos have inspired us to focus on maximum lightness, reducing material thickness without compromising strength.

Exceptional Ride Performance: The improved stiffness-to-weight ratio of 33% compared to the SL7 results in unparalleled handling. The Tarmac SL8 responds immediately to pedal inputs, ensuring efficient power transfer. Increased stiffness combines with comfort, filtering 6% more vibrations, allowing you to tackle corners with unique agility and balance.

Versatility beyond Gender Differences: The Tarmac SL8 Pro embraces the philosophy of gender-neutral design. Every cyclist, male or female, can fully leverage the advantages of this incredible racing bike. Go beyond differences and get ready to experience unparalleled riding.

Race-Ready Configuration: The Tarmac SL8 Pro is equipped with the Shimano Ultegra 8100 Di2 groupset with power meter, Roval Rapide CL II tubeless-ready wheels, SL7 stem, and Roval Rapide handlebar. Prepare for competition with a bike designed for victory. Are your legs ready to push the limits of speed?
