S-Works Tarmac SL8 Frameset - FACT 12r Carbon

S-Works Tarmac SL8 Frameset - FACT 12r Carbon

Nothing is faster than the Tarmac SL8, thanks to a combination of aerodynamics, low weight, 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. This S-Works Tarmac SL8 Frameset gives you the full platform to build your own dream race machine: an ultra-light FACT 12r Carbon frame with Rider-First Engineered™ tuning, a Speed Sniffer nose cone and narrow aero seatpost for genuine aerodynamic gains, and proven Tarmac geometry that's stiffer and more compliant than ever, with a 33% improvement in stiffness-to-weight over the SL7. Through race-simulation testing against real-world data, Specialized's Ride Science team found the Tarmac SL8 to be the fastest race bike ever made on the routes that matter — 16.6 seconds faster over 40km, 128 seconds faster over Milan-San Remo, and 20 seconds faster up the legendary Tourmalet climb.

Product details

Key features

• Ultra-light FACT 12r Carbon frame: a Rider-First Engineered™ chassis weighing just 685 grams (size 56) — the lightest full-aero Tarmac frame ever built, with a 33% gain in stiffness-to-weight over the SL7.
• Speed Sniffer aero shaping: a repositioned steer tube allows a sharper, lower-drag head tube profile, making this the most aerodynamic Tarmac Specialized has built.
• Race-proven handling: World Championship-proven geometry carried over unchanged from the SL7, so the aero and weight gains come with no compromise on the ride.
• Narrow aero seatpost with integrated wedge: a UCI-legal, low-drag S-Works FACT Carbon post keeps dirty air flowing cleanly around the legs.
• 32mm tyre clearance: genuine room for wider rubber without sacrificing the SL8's race-bike handling.
• Ready to build: 68mm threaded bottom bracket and flat-mount disc brakes for simple, no-hassle integration, plus an included stem spacer kit for SL7-style stem and Roval Rapide cockpit compatibility.
• Frame: S-Works FACT 12r Carbon, Rider First Engineered™, 685g (size 56)
• Fork: S-Works FACT 12r Carbon, 12x100mm thru-axle, flat-mount disc
