The Tarmac SL8 Expert - Ultegra Di2 from Specialized offers unbeatable speed on the track thanks to a unique fusion of advanced aerodynamics, lightweight design, and superior ride quality. Streamlined to perfection after over twenty years and eight generations of development, this is not just the fastest Tarmac yet, but possibly the quickest race bike globally.

Outperforming competitors with unrivalled balance of aero efficiency, minimal weight, stiffness, and compliance, the Tarmac SL8 has been proven to be the fastest race bike in real-world race simulations. It consistently delivers impressive speed advantages - 16.6 seconds quicker over 40km, 128 speedier seconds in Milan San Remo, and a lean 20 seconds faster ascent of the legendary Tourmalet climb.

Key Features:

  • Aero in Everything: Every aspect of the Tarmac SL8 has been designed for aerodynamic efficiency. The innovative 'Speed Sniffer' nose cone and aero seat post allows for significantly lower drag and cleaner air flow, making it our most aerodynamic bike yet.
  • Minimum Weight, Maximum Aero: Borrowing from the expertise developed crafting the Aethos, the Tarmac SL8 boasts a featherlight 685 gram frame. This pared-down weight, combined with a full aero setup, is unlike anything else on the World Tour.
  • Goes Like Hell, Rides Like Heaven: Featuring a 33% improvement in stiffness-to-weight compared to the SL7, the Tarmac SL8 delivers unprecedented ride comfort and handling. The bike is stiffer at the pedals, more responsive at the bars, and provides exceptional compliance in the saddle. This unique combination sets the standard for race bike comfort.
  • Unified Design: The Tarmac SL8 is designed for all riders, transcending outdated notions of male and female bikes. It delivers the same exceptional ride quality and handling to every rider, regardless of gender or size.
  • Di2 Performance: Equipped with a full Ultegra Di2 groupset and C38 carbon tubeless ready wheelset, the Tarmac SL8 Expert provides breakthrough performance. Combined with an SL7 stem and Specialized Expert Shallow Drop alloy handlebars, a top-notch ride experience awaits.

Savour victory with the Tarmac SL8 Expert - Ultegra Di2 by Specialized. Whether you are a seasoned competitor or a dedicated amateur rider, prepare to set personal best times and outperform your rivals. The Tarmac SL8 doesn't just change the game, it defines it.
