S-Works Tarmac SL8 - Shimano Dura-Ace Di2
We deliver! Just say when and how.
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. Your legs up for it?
Aerodynamics or lightweight alone don’t win races - speed is what matters. Delivering that speed requires creating an uncompromising combination of aerodynamics, lightweight, stiffness, and compliance. Through race simulations using real world data our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made on the routes that matter - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb.

The engineering obsessed Germans at Tour Magazine declared the Tarmac SL8, ‘the best road bike in the world’. Reaching the previously unimaginable rating of ’1.3’ *- the highest Tour score ever - Tarmac SL8 beats every competitor. Or, as these serious, data driven journalists put it, ‘No other racing bike functions better as a complete package.’
After a decade of working in the Win Tunnel, our engineers put aero where it matters, not just where it looks good. The result? A new Nose Cone called the ‘Speed Sniffer’ helps the new Tarmac SL8 be 16.6 seconds faster over 40km than the Tarmac SL7. And yes, more aero than the Venge.
We saw how the lightest production road bike in the world - the Aethos - could marry blistering response in the mountains with a supple, all-day ride. The Tarmac SL8 took those learnings from Aethos to be easily built at the UCI minimum with a full aero set up.
The Tarmac SL8 delivers a massive 33% improvement in stiffness to weight vs the SL7, all while being 6% smoother in the saddle. With World Championship proven geometry and 32mm tire clearance, it adds up to an unprecedented ride quality.
Our Ride Science team tests our solutions versus the competition before a pedal is even turned. Through complex simulations of real world race routes with identical real world data, our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made.
Creating a bike more aerodynamic, 15% lighter, with a 33% improvement in stiffness-to-weight than the 4X World Championship winning Tarmac SL7 took more than an obsessive commitment to Innovate or Die. Our engineering team created an entirely new process.
Since day one at Specialized, the rider has been the boss, so the best all arounders in the world - Remco Evenepoel, Demi Vollering - had a hand in developing and refining the Tarmac SL8. Ultimately, we co-created the fastest race bike in the world.
