Specialized Tarmac SL8 Pro Ultegra Di2 2026

Nessuna bicicletta è veloce quanto il Tarmac SL8 grazie a una combinazione di aerodinamica, leggerezza e qualità di guida precedentemente ritenuta impossibile. Dopo otto generazioni e oltre due decenni di sviluppo, non è solo il Tarmac più veloce di sempre: è la bici da corsa più veloce del mondo. Le tue gambe sono pronte?

Aerodynamics or lightness alone don't win races: what matters is speed. To achieve this speed, you need to create an uncompromising combination of aerodynamics, lightness, stiffness, and shock absorption. Thanks to complex simulations using real data, our Ride Science Team has verified that the Tarmac SL8 is the fastest race bike on any route: - 16.6 seconds over 40 km on flat terrain, 128 seconds faster on the Milan-San Remo route, 20 seconds faster on the Tourmalet climb.

The world's fastest race bike gets even faster thanks to the revolutionary aerodynamic performance of the new Roval Rapide CLX III wheels.

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 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.
The Tarmac SL8 Pro delivers exceptional performance with a full Shimano Ultegra 8100 series Di2 groupset with power meter, Roval Rapide CL III tubeless-ready wheelset, and a Roval Rapide cockpit. You’re ready to race out of the box.

'Apple Find My' technology is now integrated in all SW & Pro 4iiii power meters. Riders can now enjoy the peace of mind that comes with knowing the exact location of their bikes.

Tip: to receive the bike ready to ride, you can add the “Bici montata e regolata dai tecnici Cicli Drigani” option to your cart for €59. With this service, the bike will arrive assembled, adjusted, and ready to pedal. Without this option, the bike will be delivered in the manufacturer's original packaging and will require some technical operations before it can be used safely.
