1974 to 2024: A 50-Year Tradition of Innovation

As Specialized celebrates its 50th Anniversary of innovating to improve riders’ lives, we have our sites set on the next half century and creating the future of cycling. Join us as we look back at five decades of innovation so we can continue to Pedal the Planet Forward together.

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 tire clearance up to 38c/40mm, 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.

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 on Roubaix, it’s always heaven above.

  • 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 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.
  • The Roubaix SL8 is the smoothest road bike our Ride Science Team has ever tested—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.
  • 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 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 950 grams, the frame is lighter, utilizing lessons learned from the Aethos - the world’s lightest production frame - and Fact 10r carbon blend. Nothing in its class is faster or lighter than the Roubaix.

Roubaix SL8

At 67, having just entered retirement, I decided to purchase a bicycle, and that's essentially the whole story. I am thoroughly pleased with my choice of the Roubaix SL8 series and would suggest it to anyone in search of an affordable, high-quality carbon fiber road bike. I tried out several gravel bikes, but they seemed heavy and slow. However, the moment I tested the Roubaix, I was captivated by its performance from the very first pedal stroke. It provides an excellent ride, and even at my age, I appreciate the speed it offers with ease. If you're considering a road bike that's economical, do give the Roubaix series a chance.

Best ride ever

I have always had pure thoroughbred road bikes all my life so when the time came to change my ten years old aluminum-Tiagra bike, I was also overwhelmed by all the choices and by the hybridization of traditional bike categories. Then came the Roubaix SL8 and what a pleasant surprise it was. After only a couple of rides, I knew right away I would be making one with this beautiful machine. The smoothest ride I’ve ever felt with no compromise on performance whatsoever. Just want to spend more time on it! Would recommend 100%.

Roubaix SL8 - Beginner cyclist

As a brand new cyclist diving into the world of carbon road bikes, I was a little overwhelmed by all the choices. I knew I wanted comfort and a bike that wouldn't break the bank, and let me tell you, the Roubaix SL8 hit the sweet spot. First off, this bike is gorgeous. But the beauty goes way beyond the surface. The minute I hopped on, I was impressed by the smooth ride. The Future Shock 3.0 really is a game-changer, especially for a beginner like me. It absorbs all the bumps and road chatter, making those longer rides much more enjoyable. This bike feels perfectly comfortable and confidence-inspiring, which is exactly what I need as I build up my endurance.

Just like Sepp…the hype is real!

This guy…mind blowing. I’m not even sure where to start. I thought my Allez was a work of art, this guy is a masterpiece. I took this guy out for his maiden voyage 12 hours after he came home. Took him to my “go to” trail…I know this trail. I wanted something that I knew because I wasn’t sure how he was going to handle…what little weird things were going to “pop up”. A mile into the ride, the weirdest thing that “popped up” was how well he handled. He handles like a masterpiece. Corners, acceleration, standing, sitting, stopping, doing tiny little figure 8’s at slow speeds, this guy floats on air. Truly “Heaven Above”. This will be my last bike – I think. IF I do ever buy a new bike, which is doubtful – it will be another Roubaix…there will be no other bikes for me.
