Specialized Tarmac SL8 Pro Ultegra Di2 *DEMO*
Product Details
The Specialized Tarmac SL8 Pro represents the pinnacle of modern race bike engineering. After eight generations and over two decades of development, the Tarmac SL8 delivers a combination of aerodynamics, lightweight construction, and ride quality previously thought impossible, creating what Specialized calls the world's fastest race bike.
Built on the revolutionary Tarmac SL8 FACT 10r carbon frame using Rider First Engineering, this bike achieves unprecedented performance metrics: 16.6 seconds faster over 40km than the SL7, more aerodynamic than the Venge, and featuring a mind-bending 685-gram frameset that's 15% lighter than its predecessor. The innovative "Speed Sniffer" nose cone and repositioned steer tube create the sharpest leading edge Specialized has ever designed, optimizing airflow where it matters most while maintaining UCI minimum weight with a full aero setup.
The Pro model delivers race-ready performance straight out of the box with a complete Shimano Ultegra Di2 R8150 12-speed groupset featuring the 4iiii Precision 3+ power meter with integrated Apple Find My technology for peace of mind. The Roval Rapide CL II tubeless-ready wheelset and Roval Rapide handlebar complete the package, providing exceptional stiffness and handling precision.
Perfect for racers and performance enthusiasts who demand nothing less than the fastest, the Tarmac SL8 Pro delivers a massive 33% improvement in stiffness-to-weight over the SL7 while being 6% smoother in the saddle. With World Championship-proven geometry, 32mm tire clearance, and co-development input from world-class athletes like Remco Evenepoel and Demi Vollering, this bike goes like hell and rides like heaven.
