S-Works Roubaix SL8 LTD – SRAM RED AXS

Smoother is Faster

Smoother is Faster

Smoother is faster comes from suspending the rider, not the bike. As rough roads impact your Roubaix, our all-new Future Shock 3.0 and AfterShock technology keep you floating above the chaos - reducing impacts by 53% vs. the nearest competition.

Pioneering Endurance Geometry

Pioneering Endurance Geometry

The Roubaix’s endurance geometry delivers an “IN” the bike, not “ON” the bike feel that’s ideal for long rides. It relieves stress from your hands, arms, and shoulders, yet is ready to dissect any twisting mountain descent at full gas.

More Clearance, More Capable

More Clearance, More Capable

With tyre clearance up to 40 mm, this endurance road machine delivers better traction than ever on rough roads and even light gravel. We’ve given it every mount your adventures could need—three bottle mounts, top-tube mounts, and it’s even fender-ready.

Aero and Lightweight at the top of the Class

Aero and Lightweight at the top of the Class

The new Roubaix SL8 is our most aero yet, with new fork shaping, a reimagined downtube, and dropped seat stays. At just 825 grams, the frame is 50 grams lighter, utilizing lessons learned from the Aethos and our premium Fact 12r carbon blend. Nothing in its class is faster or lighter.

Peter Sagan’s Choice

Peter Sagan’s Choice

Roubaix with Future Shock was a game-changer for Peter Sagan as he chased Paris-Roubaix glory. But don’t take our word for it. Hear the 2018 Champion of the Hell of the North himself tell us exactly why he’s a fan of the Roubaix.

Annika Langvad’s Ride

What does the greatest XC marathon racer in history choose when she hits the road? Roubaix, of course. Annika Langvad tells us why the Roubaix is her bike of choice to deliver race-level performance on the long days she loves.

Smoother is Faster. Proven
Nothing is Faster than Diverge STR on Rough Terrain

Smoother is Faster. Proven

Suspend The Rider (STR) technology not only eats up impacts so your body doesn’t have to, but it also reduces rolling resistance to keep you rolling faster on rough terrain with up to a massive 11.3 watts of savings—all proven by the Sports University of Cologne.

Specialized Roubaix SL8: The Tech behind the World's Lightest, Fastest and Smoothest Bike

We created the endurance road category two decades ago, proving that high ergonomics means high performance. Today, the new Roubaix SL8 with Future Shock 3.0 is lighter, faster, and smoother than any road bike ever made, unleashing unmatched confidence. The road may be hell below, but it’s always heaven above on Roubaix.

Now, the smoothest endurance bike in the world is available in a gorgeous, limited Glacial Metallic color with all-new SRAM RED AXS, custom Roval graphics, silver accents, and the new Hammerhead Karoo 3 cycling computer. With only 100 worldwide, each individually numbered, they’ll be snapped up faster than Future Shock eats potholes. Don’t wait!

  • COMPLIANCE: Future Shock 3.0 is the star of the show, 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.

  • Our dropped clamp design exposes more seatpost to increase deflection, but “more” isn’t simply better. The Pavé seatpost controls that deflection for optimal vertical compliance. Together, they create AfterShock technology, which, when paired with the Roubaix’s rigid rear triangle, delivers a smooth ride with no loss in efficiency.

  • The Roubaix SL8 is the smoothest road bike our Ride Science Team has ever tested, reducing impacts at the bars and saddle by 53% compared to 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.

  • CAPABILITY: The Roubaix pioneered endurance geometry, so you ride “IN” the bike, not “ON” the bike, to relieve pressure on your hands, arms, and shoulders for capability and confidence on any road, yet it’s ready to dissect a mountain decent at full gas. Snuggle up.

  • 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.

  • Roubaix inspires really BIG days on the bike, so we’ve given it every mount your adventures could need—three bottle mounts, top-tube mounts, and it’s even fender-ready. So, go ahead and bring it all along for the ride.

  • PERFORMANCE: The new Roubaix SL8 is our most aero yet, with new aero shapes from our Free Foil library and dropped seat stays. At just 828 grams, the frame is 50 grams lighter, utilizing lessons learned from the Aethos - the world’s lightest production frame - and our premium Fact 12r carbon blend. Nothing in its class is faster or lighter than the Roubaix.
