Specialized Roubaix SL8 Expert 2025 - Road Bike











Designed for a smoother, faster ride across any tarmac, the Roubaix SL8 Expert brings together over two decades of Specialized innovation in endurance road biking. The frame is built using their high-performance FACT 10r carbon, drawing on aerodynamic tube shapes from the FreeFoil library and lessons learned from the ultra-light Aethos. It’s just 950g and includes new dropped seatstays for better aerodynamics and compliance.
Key Features:
- FACT 10r carbon frame with aero shaping and dropped seatstays
- FACT carbon fork with Future Shock 3.2 suspension system
- SRAM Rival eTap AXS 2x12 electronic drivetrain with power meter
- SRAM Rival hydraulic disc brakes for smooth, consistent braking
- Roval Terra C carbon wheels with S-Works Mondo 700x32c tyres
- S-Works Pavé seatpost and three bottle mounts for endurance rides
- Available with 0% APR finance
At the front of the bike is Future Shock 3.2, a completely redesigned suspension system offering 20mm of tunable, friction-free travel between the stem and head tube. Unlike standard forks, which deflect backward and sap speed on impacts, Future Shock keeps your bars and hands stable, allowing you to maintain momentum across broken roads, cobbles and even light gravel
Compliance continues at the rear with AfterShock technology a combination of a dropped seatpost clamp and the S-Works Pavé carbon seatpost. This setup enhances vertical flex while maintaining power transfer, resulting in a smoother ride with no loss of efficiency. Compared to competitors, the SL8 reduces impact at the bars and saddle by up to 53%, meaning less fatigue and more speed over long distances.
The Rider-First Engineered™ geometry places you in the bike for confidence and control on descents, while remaining relaxed and efficient over long miles. There’s clearance for up to 40mm tyres, and it comes stock with 32mm S-Works Mondo 2BR tyres fast, supple and capable across any surface.
Spec’d with SRAM Rival eTap AXS 2x12 wireless electronic shifting, the drivetrain delivers effortless gear changes and includes a power meter for precision training and pacing. Braking comes via SRAM hydraulic discs, and the bike rolls on lightweight, tubeless-ready Roval Terra C carbon wheels for a responsive, controlled ride.
