Specialized Tarmac SL8 Pro Road Bike Description:
The Specialized Tarmac SL8 Pro Road Bike was designed and tested to ensure no bike is faster, thanks to a combination of lightweight aerodynamics and ride quality previously thought impossible. Crafted in the shadow of eight generations of innovation, Specialized has manufactured its fastest Tarmac to date, making it the world’s fastest competition road bike; are you ready?
Specialized has found through rigorous testing that aerodynamics and overall weight aren’t what wins races; only speed is important. Crafting speed is a matter of capitalizing on every advancement found in aerodynamics, weight reduction, carbon stiffness, and compliance. Tarmac SL8 has received improvements in stiffness over Tarmac SL7, increasing the stiffness-to-weight ratio by over 33%. Add that to the aggressive response, refined handling, and world championship-proven geometry of SL8, and you’ll have every advantage expected to edge out your competition.
Specialized took a step further to issue a heightened sense of comfort to Tarmac SL8. Thanks to Rider-First Engineering, the next level of ride compliance has been achieved, delivering riders on every frame size up to 6% more compliance in the saddle with an improved sense of control at the handlebars. What’s more than that is that SL7 not only retains the proven geometry of prior iterations, but also the versatile tire clearance, enabling users to run higher volume tires up 32mm when needed.
Tarmac SL8 Pro has been equipped with SRAM’s power meter version of the Force AXS groupset, providing an even lower overall weight, responsive braking, and intuitive, reliable shifting through an ever-capable range. Performance doesn’t end at the drivetrain; a Roval Rapide integrated handlebar/stem combo furthers overall reduction of weight, while issuing a compliant, responsive cockpit that elegantly hides away cable clutter. Tubeless-ready Roval Rapide CL III aero wheels exemplify top-notch performance through a compliant deep-dish aero profile that cuts through the wind and virtually smooths all but the roughest of roads.
