Specialized S-Works Tarmac SL8 Road Bike SRAM Red 2025

Season:2025

Brand:S Works

Code:5441180354385

"The Specialized S-Works Tarmac SL8 with SRAM Red AXS is the pinnacle of road racing performance. Built with the lightest and most aerodynamic Tarmac frame ever, this bike is engineered for pure speed without compromising ride quality. The SRAM Red AXS groupset delivers effortless, wireless shifting with precision, while the power meter-equipped crankset ensures you can train and race with data-driven efficiency. Paired with Roval Rapide CLX II wheels, the SL8 offers unmatched stability and responsiveness at high speeds. If you’re chasing podiums or simply want the best road bike money can buy, the S-Works Tarmac SL8 is in a league of its own." Elliot, store manager and ex-pro triathlete.

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


After eight generations and over two decades of development, it’s more than the fastest Tarmac ever - it’s the world’s fastest race bike. Your legs up for it?

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 is the fastest race bike ever made on the routes that matter - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb.

Now, the fastest race bike in the world meets SRAM RED AXS groupset with power meter - the lightest electronic groupset ever - and a Roval Rapide CLX II tubeless-ready wheelset. All S-Works Tarmac SL8 models ship with a Roval Rapide cockpit to save weight and for the fastest possible leading edge.

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 optimized for maximum advantage with the Tarmac’s new nose cone - the Speed Sniffer. By moving the steer tube back - the tube that determines head tube width - the leading edge of the head tube can be much sharper, delivering a much lower drag shape. Utilizing new UCI rules, the Tarmac SL8 has the narrowest, most aero seat post we’ve ever made ensuring fast moving, dirty air around the legs can flow back more cleanly. Doesn’t victory smell sweet?
  • 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 and lighter than anything on else on the World Tour*. 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. The frame’s shape carries load so efficiently that extra carbon stiffness layers become redundant. *Unless of course you count the time Kasper Asgreen raced our 585 gram Aethos frame during a Tour stage.
  • 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. Thanks to our Rider-First Engineering, every rider, regardless of size, gets the same unprecedented ride quality and handling. In the saddle the Tarmac SL8 delivers 6% more compliance, floating over rough road with a supple feel unique in the high strung world of race bikes. Tarmac’s proven geometry and 32mm tire clearance are identical to the SL7, ensuring easy adaptation and the versatility to run higher volume tires when needed.
  • BEYOND GENDER: There can be more difference between two male cyclists than between a male and female. Gender alone doesn’t provide nearly enough data to specialize and that means creating male or female bikes is arbitrary and outdated. Every rider can get the next level advantage of Tarmac SL8. It’s time to go Beyond Gender.
  • S-Works Tarmac SL8 is spec’d with only the best components. A full SRAM RED AXS groupset with power meter - the lightest electronic groupset ever - and a Roval Rapide CLX II tubeless-ready wheelset are the perfect complement to the world’s fastest frame. All S-Works Tarmac SL8 models ship with a Roval Rapide cockpit to save weight and for the fastest possible leading edge.

Bikes are professionally built by trained technicians to ensure optimal performance, safety, and comfort for each customer. Every component is carefully assembled and adjusted to meet the rider’s specific needs and preferences.

Our convenient man-in-van delivery service brings your professionally built bike straight to your doorstep. A dedicated technician ensures it arrives fully assembled, ready to ride, and adjusted to your specifications.
