Tarmac SL8 S-Works AXS Description:

Spec'd with SRAM Red AXS E1, the Tarmac SL8 S-Works model provides a high-level of electronic shifting performance and SRAM's game-changing one-finger braking performance. For this build, Specialized has included a RED AXS crank-based power meter allowing riders to take their training and pacing to the next level. On top of that, deep-rimmed Roval Rapide CL II wheels provide a high level of stability in the wind and are super stiff (plus they can be easily set up tubeless). On the whole, the SL8 is a winning formula designed to take on the most competitive races in the world.


Features:

  • Aero In Everything design prioritizes aerodynamics in every element of the frame design
  • The "Speed Sniffer" sets the headtube back and creates a sharper edge and lower drag shape
  • Lighter than the SL7 while remaining super stiff (33% increase in stiffness-to-weight ratio)
  • S-Works Tarmac SL8 FACT carbon seatpost is narrower and more aero 
  • Roval Rapide CL II wheels provide stiffness and stability with a 30mm external width for ultimate aerodynamics 
  • SRAM Red AXS E1 provides the best shifting and braking experience SRAM has to offer
  • Crankset-integrated Red AXS dual power meter provides an additional level of cycling metrics
  • 32mm tire clearance allows riders to run wider road tires
  • Frame is designed to be "beyond gender" as Specialized research shows there is no need for separate bike designs for men and women
  • Threaded BSA bottom bracket provides easy maintenance and is less likely to develop creaking noises
  • Includes integrated bike computer mount
