2025 S-Works Roubaix SL8 Road Bike Frameset - Gloss Carbon/Red to Gold

Season:2025

Brand:Specialized

Code:42218315428634

Specialized revolutionised the endurance road bike category two decades ago, proving that comfort drives performance. Now, the all-new Specialized Roubaix SL8 Road Bike with Future Shock 3.0 is the pinnacle of speed, lightweight design, and smoothness, offering unparalleled confidence on any road. While the road below may be rough, the Roubaix ensures a smooth, controlled ride.

Unmatched Compliance: The Future Shock 3.0 system takes center stage, offering unparalleled adjustability and durability. Every rider, regardless of position, benefits from 20mm of smooth, friction-free travel between the stem and head tube, keeping the handlebars steady for a smoother ride. Specialized's innovative dropped clamp design increases seatpost deflection, optimised by the Pavé seatpost for perfect vertical compliance. Combined with the Roubaix’s rigid rear triangle, this created AfterShock technology, delivering a buttery-smooth ride with zero loss in efficiency. The Roubaix SL8 is the smoothest road bike Specialized's Ride Science Team has ever tested, reducing impacts at the bars and saddle by 53% compared to competitors. Unlike traditional forks, which deflect backward on impact and slow you down, the Future Shock 3.0 keeps your momentum steady, proving that smoother truly is faster.

Enhanced Capability: The Roubaix set the standard for endurance geometry, positioning you in the bike rather than on it, reducing pressure on your hands, arms, and shoulders for confident handling on any terrain. Get ready to tackle mountain descents at full throttle. With clearance for up to 38c/40mm tyres, this bike offers unmatched traction on rough roads and light gravel, all without sacrificing efficiency thanks to Specialized's lightweight, high-performance tyres.

Ready for Adventure: The Roubaix SL8 is built for epic rides, equipped with all the mounts you need for long adventures; three bottle mounts, top-tube mounts, and fender/mudguard compatibility. Whether you’re tackling century rides or multi-day tours, the Roubaix is ready to carry everything you need.

Performance Redefined: The new Roubaix SL8 is Specialized's most aerodynamic yet, featuring advanced aero shapes from their Free Foil library and dropped seat stays. Weighing in at just 828g, the frame is 50g lighter, drawing from the design insights of the Aethos (the world’s lightest production frame) and Specialized's premium Fact 12r carbon blend. In its class, nothing beats the Roubaix in speed or weight.
