Specialized Tarmac SL8 Expert Ultegra Di2 Carbon Road Bike In Deep Lake

Season:2025

Brand:Specialized

Nothing is faster than the Tarmac SL8 Expert Ultegra Di2 thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible.

Aerodynamics or lightweight alone don’t win races - speed is what matters. Delivering that speed requires creating an uncompromising combination of aerodynamics, lightweight, stiffness, and compliance. Through race simulations using real world data our Ride Science team knows the Tarmac SL8 carbon road bike is the fastest race bike ever made on the routes that matter.

Features:

  • AERO IN EVERYTHING: We’re putting aero where it matters - the leading edge - not just where it looks good. In the process we’ve created our most aerodynamic road bike ever. Yes, it’s more aero than the Venge. Clean air is optimised for maximum advantage with the Tarmac’s new nose cone - the Speed Sniffer.
  • MINIMUM WEIGHT, MAXIMUM AERO: Tarmac SL8 took learnings from Aethos to be easily built at the UCI minimum with a full aero set up. The team delivered a mind bending, scale tickling 685 gram frame - 15% lighter than the Tarmac SL7. With the ability to make lightweight a top priority in the down tube, seat tube, and rear of the bike lessons from Aethos were applied.
  • GOES LIKE HELL, RIDES LIKE HEAVEN: With massive gains in stiffness-to-weight - an improvement of 33% over the SL7 - the Tarmac SL8 takes legendary handling, aggressive responsiveness and World Championship proven geometry to the next level. The bike is stiffer at the pedals, more precise at the bars, and combines it with a compliant ride in the saddle that sets a new benchmark for race bike comfort.
