Specialized S-Works Tarmac SL8 SRAM RED AXS bicycle

The fastest racing bike in the world. Even faster.

The bicycle Specialized S-Works Tarmac SL8 SRAM RED AXS represents the pinnacle of road cycling innovation. After eight generations and over 20 years of development, the Tarmac SL8 combines advanced aerodynamics, ultra-lightweight and a revolutionary ride quality. The result? The fastest racing bike ever built.

Now available with the brand new SRAM RED AXS group with powermeter, the lightest and most advanced electronic group on the market, and equipped with Roval Rapide CLX III tubeless ready wheels paired with the integrated Roval Rapide cockpit for unprecedented aerodynamic efficiency.

Strengths of the Tarmac SL8 SRAM RED AXS

Aerodynamics where it really matters

The design of the Tarmac SL8 is the result of advanced studies in the wind tunnel:

• New "Speed Sniffer" structure: sharper head tube for reduced frontal resistance.

• Most aerodynamic seatpost ever made by Specialized, compliant with new UCI rules.

• Better airflow of the turbulent air generated by the cyclist's legs.

Minimum weight, maximum speed

Thanks to the experience gained with the Aethos, the FACT 12r carbon frame weighs only 685 grams, resulting in:

• 15% lighter than the Tarmac SL7.

• Lighter than any other World Tour race frame*.
  (*Except for the 585 g Aethos used by Kasper Asgreen in a Tour stage.)

Comfort and responsiveness at the highest levels

• +33% stiffness compared to the SL7 model for an even more immediate response.

• +6% vibration absorption, for a smooth ride even on rough asphalt.

• Proven geometry of the Tarmac and space for tires up to 32 mm: versatility and comfort in every condition.

A bike beyond gender labels

Specialized designs for the cyclist, not the gender. The S-Works Tarmac SL8 is designed to offer maximum performance to all riders, regardless of sex or size.
