S-Works Tarmac SL8 Frameset
FACT 12r Carbon · 685g Frame · 32mm Tire Clearance · Win Tunnel

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. 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the Tourmalet.

  • 685g FACT 12r Carbon Frame: Lightest Tarmac ever, 15% lighter than SL7.
  • FACT 12r Carbon Fork: Full carbon, 12x100mm thru-axle, flat-mount disc.
  • Win Tunnel Engineered: Most aerodynamic Tarmac ever — faster than the Venge.
  • 33% Stiffness-to-Weight Gain: Over SL7, legendary handling with improved compliance.
  • 32mm Tire Clearance: Identical to SL7, versatile enough for higher volume tires.
  • 68mm Threaded BB: Standard BSA, no special tools required.
  • Ceramic Speed SLT Headset Bearings: Friction-free, долговечные.
  • Roval Rapide Cockpit Compatible: Spacers kit included for SL7 stem + Rapide cockpit setup.

Frameset weight: 1.38kg (56cm). Seven sizes: 44, 49, 52, 54, 56, 58, 61. Build your dream race machine.

685g FACT 12r Carbon Frame
Lightest Tarmac ever — 15% lighter than SL7. Lessons from Aethos applied: the frame's shape carries load so efficiently that extra carbon stiffness layers become redundant. UCI minimum weight ready with full aero setup.
Speed Sniffer Nose Cone
By moving the steer tube back, the leading edge of the head tube can be much sharper — delivering a much lower drag shape. Clean air is optimized for maximum advantage.
Win Tunnel Aerodynamics
Most aerodynamic Tarmac ever — even faster than the Venge. Aero where it matters (the leading edge), not just where it looks good. Narrowest, most aero seat post ever made.
33% Stiffness-to-Weight Improvement
Stiffer at the pedals, more precise at the bars, yet 6% more compliance in the saddle. Rider-First Engineering ensures every size gets the same unprecedented ride quality.
Ride-First Engineering
Every rider, regardless of size, gets the same unprecedented ride quality and handling. Proven Tarmac geometry identical to SL7 for easy adaptation.
Clean Integration
68mm threaded BB, flat mount disc, seamless internal cable routing, Tarmac integrated wedge seat binder. Headset spacers kit included for SL7 stem + Roval Rapide cockpit use.
