SPECIALIZED TARMAC SL8 PRO BIKE

No bicycle is as fast as the Tarmac SL8, thanks to a combination of aerodynamics, lightness, and ride quality previously thought impossible. After eight generations and over two decades of development, it’s not just the fastest Tarmac ever: it’s the fastest racing bike in the world. Are your legs ready?

Aerodynamics or lightness alone don’t win races: what matters is speed. To achieve that speed, you need an uncompromising balance of aerodynamics, weight, stiffness, and compliance. Thanks to complex simulations using real-world data, our Ride Science Team has proven that the Tarmac SL8 is the fastest race bike on any course: -16.6 seconds over 40 km flat, 128 seconds faster on the Milan-Sanremo route, 20 seconds faster on the Tourmalet climb.

The fastest racing bike in the world gets even faster thanks to the revolutionary aerodynamic performance of the new Roval Rapide CLX III wheels.

SPECIALIZED TARMAC SL8 PRO key features:

• We put aerodynamics where it matters — at the leading edge — not just where it looks good. The Tarmac SL8 is the most aerodynamic road bike ever created, even more aero than the Venge.
• Clean air is optimized thanks to the new Speed Sniffer nose cone, with a recessed head tube and sharp edge to reduce drag.
• The narrowest seatpost ever made by Specialized takes advantage of the new UCI rules, allowing cleaner airflow around the rider’s legs.
• Frame weighs only 685 g, 15% lighter than the SL7 and lighter than any other bike in the World Tour*. (*Excluding the Aethos at 585 g used by Kasper Asgreen in competition).
• The frame design distributes load so effectively that no extra carbon layers are needed for stiffness.
• Stiffness-to-weight improved by 33% compared to the SL7: stiffer at the pedals, more precise at the bars, and more comfortable in the saddle.
• +6% compliance: the Tarmac SL8 glides over rough surfaces with a smoother ride feel compared to traditional race bikes.
• Proven geometry and clearance for 32 mm tires, identical to the SL7, for greater versatility.
• Every rider, regardless of size or gender, experiences the same ride quality thanks to Rider-First Engineering.
• Pro build: Shimano Ultegra 8100 Di2 with power meter, Roval Rapide CL III tubeless-ready wheels, Roval Rapide cockpit. Race-ready out of the box.
• Apple Find My technology integrated in all SW & Pro 4iiii power meters to always keep track of your bike.
