Roubaix SL8 Comp

Two decades ago, we created the Road Endurance category, proving that ergonomics improve performance. Today, the Roubaix SL8, with the Future Shock 3.0 damper, is lighter, faster, and more comfortable than any other road bike. The road may be hellish under your tires, but riding the new Roubaix, you'll feel like you're in heaven.

VIBRATION ABSORPTION: The Future Shock 3.0 damper is the new star in the firmament, more adjustable and durable. Regardless of riding position, every rider can enjoy 20mm of friction-free travel between the stem and the head tube. Hands remain firmly on the handlebars, ensuring a smoother ride with greater control for faster, safer, and more confident riding.

The low-clamp design exposes more of the seatpost to increase its flex. The Pavé seatpost 'controls' this movement for optimal absorption of vibrations in the vertical plane. These two features combine to create 'AfterShock' technology, and when combined with the Roubaix's stiff rear end, they create a smooth ride without compromising efficiency.

The Roubaix SL8 is the most comfortable road bike our Ride Science Team has ever tested—it reduces handlebar impacts by 53% compared to other bikes in this category. With the Future Shock 3.0 damper, the wheel flies over obstacles while the rider remains stable and maintains a line on rough terrain. Normally, the fork flexes backward on an impact, causing a loss of speed. It's scientifically proven: more comfortable equals faster.

CAPABILITY: The Roubaix pioneered endurance geometry, giving you the feeling of pedaling 'in' the bike, not 'on' it. This reduces pressure on your hands, shoulders, and arms, giving you capability and confidence on any road.
With clearance for tires up to 38c/40mm, this endurance road bike provides exceptional traction on rough roads or gravel. Thanks to the lightweight and efficient Specialized tires, this wider tire width doesn't come at a disadvantage.

The Roubaix makes you want to spend long days in the saddle, so we decided to equip it with everything you could possibly need for cycling adventures - three bottle cage mounts, a top tube bag mount, and provision for mudguards. All that's left to do is go!

PERFORMANCE: The new Roubaix SL8 is the most aerodynamic in its class, with new tube profiles generated by our Free Foil library and dropped seatstays. Using the Aethos project—the lightest production road bike—we've crafted a new frame that weighs just 825 grams, made from FACT 12r carbon and 50 grams lighter than the previous model. No other bike in this category is faster or lighter than the new Roubaix.
