Specialized Tarmac SL8 Pro Force eTap AXS Road Bike
In the world of cycling, speed reigns supreme, and the Tarmac SL8 has emerged as the unrivaled champion, pushing the boundaries of aerodynamics, lightweight design, and ride quality to heights previously deemed unattainable. Embarking on a journey spanning eight generations and over two decades of relentless innovation, the Tarmac SL8 isn't just the fastest Tarmac iteration – it stakes its claim as the swiftest race bike on the planet. Are you ready to unleash your full potential?
AERO IN EVERYTHING: Redefining Aerodynamics
The Tarmac SL8's quest for ultimate speed has revolutionized the very concept of aerodynamics. Rather than merely chasing a sleek appearance, the focus has been on strategically placing aero elements where they truly matter – the leading edge. This groundbreaking approach has birthed the most aerodynamic road bike ever conceived, outshining even the Venge in terms of wind-cheating prowess.
Central to this achievement is the introduction of the Speed Sniffer – the Tarmac's new nose cone. By ingeniously relocating the steer tube backward, the head tube's leading edge assumes a remarkably sharper form, significantly minimizing drag. Leveraging the latest UCI regulations, the Tarmac SL8 features an incredibly narrow, supremely aero seat post, facilitating smoother airflow around the legs and reducing turbulence. Victory becomes sweeter with every pedal stroke.
MINIMUM WEIGHT, MAXIMUM AERO: Aethos-Inspired Ingenuity
Drawing inspiration from the Aethos model, the Tarmac SL8 pushes the envelope further by achieving UCI minimum weight regulations with a full aero setup. The result? A frame that defies expectations, weighing in at a mere 685 grams – a staggering 15% lighter than its predecessor, the Tarmac SL7, and trumping other contenders on the World Tour circuit.
This weight reduction is masterfully distributed across key areas like the down tube, seat tube, and rear, capitalizing on Aethos' insights. The frame's design optimally manages load distribution, rendering additional carbon stiffness layers obsolete. Notably, the illustrious Kasper Asgreen's Tour stage with the 585 gram Aethos frame stands as a testament to this engineering marvel.
GOES LIKE HELL, RIDES LIKE HEAVEN: A Paradigm Shift in Performance
The Tarmac SL8 achieves an impressive 33% enhancement in stiffness-to-weight ratio compared to its predecessor, the SL7, elevating its handling and responsiveness to legendary status. A newfound precision at the handlebars and increased pedal stiffness converge to create a cycling experience that defies limits.
But the Tarmac SL8 isn't content with performance alone; it raises the bar for race bike comfort. Embracing Rider-First Engineering, riders of all sizes relish the same unparalleled ride quality. On the saddle, the Tarmac SL8's compliance is augmented by 6%, gliding over uneven terrains with an unprecedented suppleness, a rarity in the world of high-performance race bikes. The geometry and 32mm tire clearance mirror the SL7, ensuring seamless adaptability and the option for higher volume tires when the road demands.
BEYOND GENDER: Shattering Stereotypes
In a pioneering move, the Tarmac SL8 transcends gender distinctions. Acknowledging the intricate variations between individual cyclists, the notion of creating bikes exclusively for male or female riders is relegated to the past. With the Tarmac SL8, every cyclist gains access to a new realm of advantage, untethered by gender-based constraints. It's a testament to the brand's commitment to inclusivity and progress.
The Tarmac SL8 Pro delivers exceptional performance with a full SRAM Force eTap AXS groupset with power meter, Roval Rapide CL II tubeless-ready wheelset, and a Roval Rapide Handlebar with an SL7 stem. You’re ready to race out of the box.
