The 2025 Specialized S-Works Roubaix SL8 Di2 Road Bike is lighter, faster, and smoother than any road bike ever made, unleashing unmatched confidence.

The Roubaix SL8 reduces impacts at the bars and saddle by 53% compared to the nearest competition. With Roubaix’s Future Shock 3.0, the wheel quickly moves over the bump, while rider mass remains stable, maintaining momentum in rough terrain. Typical forks deflect backward on impact, causing a measurable loss in speed. It’s a scientific fact: Smoother is indeed faster. The Roubaix pioneered endurance geometry, so you ride “IN” the bike, not “ON” the bike, to relieve pressure on your hands, arms, and shoulders for capability and confidence on any road, yet it’s ready to dissect a mountain decent at full gas. With tyre clearance up to 40mm, this endurance road machine delivers better traction than ever on rough roads and even light gravel.

As you'd expect from an S-Works bike this version of the Roubaix comes with the best equipment including 12 speed Dura-Ace gearing, Roval Terra CLX II wheels and a 4iiii Precision Pro dual-sided power meter.
