Nothing is faster than the Tarmac SL8. Combining aerodynamics, light weight, stiffness and compliance in a way previously thought impossible, it's the fastest Tarmac ever and a proven World Tour race bike.

The Pro build pairs a FACT 10r carbon frame with Roval Rapide CL III wheels, the integrated Roval Rapide cockpit and your choice of SRAM Force AXS or Shimano Ultegra Di2, both with a power meter. It's race-ready out of the box at 7.25kg (size 56).

Aero in Everything

After a decade in the Win Tunnel, Specialized put aero where it matters, not just where it looks good. The 'Speed Sniffer' nose cone helps make the Tarmac SL8 16.6 seconds faster over 40km than the SL7 – and more aero than the Venge.

A sharper head tube leading edge and the narrowest seatpost Specialized has ever made keep the air flowing cleanly around bike and rider.

Minimum Weight, Maximum Aero

Taking lessons from the Aethos, the Tarmac SL8 was designed to be built easily to the UCI minimum weight with a full aero set-up.

The S-Works frame weighs just 685g, 15% lighter than the SL7, because its shapes carry load so efficiently that extra stiffening layers aren't needed.

Goes Like Hell, Rides Like Heaven

The Tarmac SL8 is 33% stiffer for its weight than the SL7, yet 6% smoother in the saddle.

With World Championship-proven geometry, Rider-First Engineering and 32mm tyre clearance, it combines precise handling with remarkable comfort for a race bike.

Made in Racing

Remco Evenepoel and Demi Vollering helped develop and refine the Tarmac SL8.

Ride Science simulations on real race routes show it's 16.6 seconds faster over 40km, 128 seconds faster over Milan-San Remo and 20 seconds faster up the Tourmalet than the SL7.
