2025 Specialized Roubaix SL8 Sport 105, Unisex Road Bike - Metallic Sapphire

The all-new Roubaix SL8 with Future Shock 3.0 is lighter, faster, and smoother than any road bike ever made, reducing impacts at the bars and saddle by 53% vs. 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 SL8 Sport 105 is highlighted by the Shimano 105 22 speed mechanical groupset and fast but strong DT Swiss 540 wheelset.

• Roubaix inspires really BIG days on the bike, so it has every mount your adventures could need - three bottle mounts, top-tube mounts, and it’s even fender-ready.
• With tire clearance up to 38c/40mm, this endurance road machine delivers better traction than ever on rough roads and even light gravel. Thanks to lightweight, super-efficient Specialized tires, that extra tire volume and traction comes with no downsides.
• The new Roubaix SL8 is the most aero yet, with new aero shapes from the Specialized Free Foil library and dropped seat stays. At just 950 grams, the frame is lighter, utilizing lessons learned from the Aethos - the world’s lightest production frame - and Fact 10r carbon blend.
• Future Shock 3.0 is more tunable, adjustable, and durable than ever. Now, regardless of position on the bike, every rider experiences 20mm of smooth, stiction-free travel between the stem and head tube. Future Shock helps keep your hands and bars steady for a smoother ride with more control to stay fast, safe, and confident.
• The dropped clamp design exposes more seatpost to increase deflection. The Pavé seatpost controls that deflection for the optimal vertical compliance. Together they create AfterShock technology, and when paired with the Roubaix’s rigid rear triangle, deliver a smooth ride with no loss in efficiency.
