Specialized Tarmac SL8 Expert Di2 Deep Lake/Green 2025

Specialized Tarmac Sl8 Expert Di2 Deep Lake/Green 2025

The Tarmac SL8 is unbeatably fast. The most advanced aerodynamics and low weight result in a ride quality that seemed unattainable. After eight generations and more than twenty years of development, it's not just the fastest Tarmac ever - it's the fastest road bike in the world. Are you ready?

Aerodynamics and low weight alone don't decide races - at the finish line, it's speed that counts. To reach race speed, a very specific balance of aerodynamics, lightness, stiffness and compliance is necessary. Our Ride Science team has found through race simulations based on real data that the Tarmac SL8 is the fastest racing bike ever built on the decisive routes. A full 16.6 seconds faster over 40 km, 128 seconds faster in Milan-Sanremo and 20 seconds faster on the Tourmalet.

AERO-AVANTGARDE:

For us, aero is the surfaces that really matter, not the ones that look best. With this philosophy, we created our most aerodynamic road bike ever. And yes, it is more aerodynamic than the Venge. The Tarmac SL8's redesigned head tube maintains airflow better because the surface at the front is more tapered. We call it the Speed ​​Sniffer, and with it the more streamlined cross-section of the head tube creates much less drag. In addition, in line with the new UCI rules, we designed the Tarmac SL8 to be the narrowest and most aerodynamic Specialized seatpost ever. This allows the fast-moving, turbulent air around the legs to flow away more cleanly. A bike with a sense of victory.

MINIMUM WEIGHT, MAXIMUM AERO:

The Tarmac SL8 takes the lessons learned from the development of the Aethos and easily meets the UCI weight limit with a full aero setup. Our team developed an incredible 685 gram frame - 15% lighter than the Tarmac SL7 and lighter than any other bike on the World Tour. The fact that Kasper Asgreen rode our Aethos on a Tour stage, whose frame weighs just 585 grams, somehow doesn't count. The new technical possibilities enabled us to optimise the weight of the Tarmac's down tube, seat tube and rear end, because the new shape of the frame distributes the load so efficiently that additional carbon layers for greater stiffness are no longer necessary.

INSTANT ACCELERATION WITH MORE COMFORT:

With a massive improvement in stiffness to weight ratio – an astonishing 33% over the SL7 – the Tarmac SL8 takes the legendary handling, aggressive responsiveness and World Tour-proven geometry to a new level. Stiffer at the bottom bracket, more precise at the handlebars and more compliant in the saddle, the bike sets new standards for competition bike performance and comfort. Our Rider-First Engineering™ concept ensures that every rider enjoys the same ride quality and handling, regardless of size. The Tarmac SL8 offers 6% more compliance in the saddle, gliding smoothly over rough roads – unique in the high-pressure world of road cycling. And when conditions demand it, the 32mm tire clearance allows you to run higher volume tires.

GENDER NEUTRAL:

Our experience from product development tells us that there can be more differences between two riders of the same gender than between two riders of different genders. Gender alone does not create a basis for gender-specific geometries. Frames specifically for men or women are therefore unfounded and outdated. With a Tarmac SL8 for everyone, every rider can secure the decisive advantage.The Tarmac SL8 Expert is a powerful bike with outstanding performance. It comes with a complete Ultegra Di2 groupset with power meter, C38 carbon wheelset (tubeless-ready) and an SL7 stem with Specialized Expert Shallow Drop aluminum handlebars.
