One Bike to Rule Them All
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.’

🏁 Built for Champions
From mountain passes to breakaway sprints, the S-Works Tarmac SL8 is your ultimate race machine – aero, ultra-light, and flawlessly fast.
Our most aerodynamic race bike ever
Aero in Everything
After a decade of work in the Win Tunnel, our engineers have placed aero where it really 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 40 km than the Tarmac SL7. And yes, more aerodynamic than the Venge.
685 gram frame
Minimum weight, maximum aerodynamics
We’ve seen how the world’s lightest production road bike—the Aethos—can combine lightning-fast responsiveness in the mountains with smooth, all-day handling. The Tarmac SL8 has learned from the Aethos and is built to UCI minimum standards with a full aerodynamic package.
More rigid and more comfortable
When rigidity and agility rhyme with comfort
The Tarmac SL8 offers a massive 33% improvement in weight-to-stiffness ratio over the SL7, while being 6% more comfortable in the saddle. With world championship-proven geometry and 32mm tire clearance, it delivers unprecedented ride quality.
