Tarmac SL8 – The Fastest Race Bike in the World

The Tarmac SL8 is designed to deliver maximum speed by perfectly balancing aerodynamics, lightness, and ride quality.

Aerodynamics

The SL8 is even more aerodynamic than the Venge. The fork steerer is set back to reduce drag, and the seatpost is the most aerodynamic we've ever made, improving airflow around the rider's legs.

Lightness

The frame weighs just 685g, 15% lighter than the previous model and the lightest in the World Tour. Its structure is optimized to eliminate excess material without compromising strength.

Ride Quality

The stiffness-to-weight ratio is improved by 33%, ensuring responsiveness and precision without sacrificing comfort. The Tarmac SL8 absorbs 6% more road vibrations than the SL7, maintaining its proven geometry and accommodating tires up to 32mm wide.

Inclusivity

Designed without gender distinctions, it adapts to every rider to maximize performance.
