Specialized S-Works Roubaix SL8 Frameset - 2024-25, 49 cm

2024–2025 Specialized S-Works Roubaix SL8 Frameset, Size 49

The S-Works Roubaix SL8 frameset represents the pinnacle of endurance road bike design, combining cutting-edge comfort technology with race-level performance. Built from Specialized FACT 12R carbon, this frameset is incredibly light, responsive, and refined, making it ideal for long rides, rough pavement, and high-speed endurance racing. With a total frameset weight of approximately 2 kg, it delivers efficiency without compromising ride quality.

At the heart of the Roubaix SL8 is the latest Future Shock 3.3 system with Smooth Boot, seamlessly integrated into the carbon fork. This system provides controlled front-end compliance, dramatically reducing road vibration and fatigue while maintaining precise steering and sprint stiffness. It’s one of the most advanced comfort technologies available on any road bike today.

This brand-new frameset (0 miles) includes the FACT carbon fork, derailleur hanger, and the S-Works Pave carbon seatpost, which further enhances vertical compliance at the rear for a balanced, smooth ride. Size 49 cm is best suited for riders approximately 5’0” to 5’5”, making it a perfect foundation for a high-end custom build tailored to smaller riders who still demand top-tier performance.

Whether you’re building a dream endurance bike, a fast all-road machine, or a long-distance race setup, the Roubaix SL8 frameset offers unmatched versatility, comfort, and prestige from Specialized’s flagship S-Works line.

Why we love it

We love the S-Works Roubaix SL8 because it proves that comfort and performance don’t have to be opposites. The FACT 12R carbon layup feels incredibly lively, the Future Shock 3.3 smooths rough roads without dulling the ride, and the overall design makes long days in the saddle faster and more enjoyable. It’s the ultimate canvas for a premium custom build and one of the most advanced endurance road frames ever made.
