Specialized Tarmac SL8 S-Works eTap: The Fastest Race Bike Ever Built

The Specialized Tarmac SL8 S-Works eTap redefines speed with an uncompromising combination of aerodynamics, lightweight construction, and unmatched ride quality. After over two decades of development across eight generations, the Tarmac SL8 is now the world’s fastest race bike. Built for serious riders, this bike is engineered to cut through the wind while maintaining a light, responsive feel, making it the ideal choice for competitive cyclists.

Key Benefits for Riders

Unmatched Speed and Aerodynamics

The Tarmac SL8’s aerodynamic design delivers an incredibly fast ride by optimizing the leading edge of the bike. This includes the Speed Sniffer, which sharpens the front of the head tube, reducing drag, and the ultra-narrow seatpost that lets dirty air flow cleanly off the legs. The result is a bike that is faster than ever before, shaving off precious seconds on key routes — 16.6 seconds faster over 40 km, 128 seconds over Milan San Remo, and 20 seconds faster on the legendary Tourmalet climb.

Lightweight and Responsive

The Tarmac SL8 is built using FACT 12r carbon to create the lightest frame possible, weighing just 6.66 kg (14 lb, 10.9 oz). This is made possible by Rider-First Engineered™ geometry, which ensures consistent performance, handling, and ride quality, no matter your frame size. The bike’s frame is 1.1 lbs (0.5 kg) lighter than its predecessor, helping you gain speed without sacrificing durability or stiffness.

Advanced Technology with SRAM RED AXS

Equipped with the SRAM RED AXS groupset, including a power meter, the Tarmac SL8 offers the lightest and most precise electronic shifting ever. The groupset delivers smooth, responsive shifts while reducing weight and complexity. With hydraulic disc brakes and the SRAM RED 160mm rotors, you’ll have the stopping power you need for all kinds of riding conditions.

Enhanced Comfort and Control

The Tarmac SL8 is designed for long-lasting comfort, featuring an upright body position and Body Geometry touchpoints to ensure comfort and control over long rides or intense sprints. The S-Works Power with Mirror saddle offers advanced pressure relief, while the Roval Rapide CLX II tubeless-ready wheelset provides enhanced performance and reduced weight for quicker acceleration and smooth handling.

Long-Term Durability and Performance

The S-Works FACT 12r Carbon frame is engineered to handle the toughest rides, offering improved compliance and stiffness for precise control without compromising comfort. The frame also features Win Tunnel Engineering and clean internal cable routing to minimize drag and enhance aerodynamics, allowing you to go faster, longer.
