Specialized Tarmac SL8 Expert Rival eTap AXS 2025 bicycle. Manufacturer reference: 94925-3452

Specialized Tarmac SL8 Expert road bike from 2025. Nothing is faster than the Tarmac SL8. The six combination of aerodynamics, weight and driving quality make it the most advanced and developed competition bicycle. Amb vuit generations and more than two decades of innovation, the SL8 is not only the fastest Tarmac in history: it is the fastest competition bike in the world.

The speed is the real object. To achieve this, it combines the concessions of aerodynamics, lightness, rigidity and comfort. Our Ride Science team has carried out simulations of both real courses and has demonstrated that the Tarmac SL8 is the fastest bicycle on the routes that matter: 16.6 seconds faster over 40 km, 128 seconds faster on the Milà-San Remo and 20 seconds faster on the legendary Tourmalet.

• Total aerodynamics: We have placed the aerodynamic elements there to make the difference, not just on their appearance. The new Speed ​​Sniffer, the sharper profile of the steering cap, optimizes air flow with a sharper frontal height, reducing resistance. Furthermore, the seat post, the narrowest one we have manufactured in Spain, improves the passage of the raw air that surrounds the stems. Faster fins i tot than the Venge.
• Minimum weight, maximum performance: the 685 g FACT 10r quad is 15% lighter than the Tarmac SL7 and lighter than any other World Tour bike*. We have applied the experience of the Aethos to achieve forms that support the job efficiently, eliminating the need for additional reinforcement capes.
  *Except that Kasper Asgreen will compete with a 585 g Aethos in the Tour.
• Competitive behavior, luxurious comfort: with a 33% improvement in the stiffness/weight ratio compared to the SL7, the SL8 maintained a cool geometry, aggressive handling and excellent comfort. The Rider-First Engineering system ensures excellent handling for all sizes, while the space for the 32 mm fin covers offers versatility.
• Beyond the genre: designing bicycles per genre is an obsolet concept. A la Tarmac SL8 tothom hi trobarà avantatges, regardless of its genre. It's time to look more beyond the labels.
• The Tarmac SL8 Expert Rival eTap AXS offers exceptional performance. Equipped with a complete SRAM Rival eTap AXS group with a power meter, Roval C38 tubeless ready carbon wheels, Specialized Expert Shallow Drop aluminum handlebars and integrated SL7 stem. A high-level bicycle at a more affordable price.
