Features specialized bike s-works roubaix sl8 ltd 2025
We created the Gran Fondo 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 more comfortable than any road bike ever made, unleashing unrivaled confidence. The road may be hell, but it’s always heaven on a Roubaix.
Now the world's most comfortable Gran Fondo bike is available in a gorgeous, limited Glacial Metallic color with the new SRAM RED AXS groupset, custom Roval graphics, silver accents, and the new Hammerhead Karoo 3 cycling computer. With just 100 units worldwide, each individually numbered, they'll sell out faster than a Future Shock eating up potholes. Don't wait.
COMFORT: The Future Shock 3.0 is the star of the show, more adjustable and durable than ever. Now, regardless of position on the bike, every rider experiences 20mm of smooth, stick-free travel between the stem and head tube. Future Shock helps keep your hands and bars planted for a smoother, more controlled ride to ride fast, safe, and confident.
Our lowest seatpost clamp design exposes more of the seatpost for increased flex - but "more" isn't simply better. The Pavé seatpost controls that flex for optimal vertical comfort. Together they create AfterShock technology, and when combined with the Roubaix’s stiff rear triangle, they provide a smooth ride without loss of efficiency.
The Roubaix SL8 is the most comfortable road bike our Ride Science team has ever tested, reducing shock to the handlebars and saddle by 53% versus the nearest competition. With Roubaix’s Future Shock 3.0, the wheel rolls quickly over the bump, while the rider’s mass remains stable, maintaining momentum on rough terrain. Traditional forks flex backward on impact, causing a measurable loss of speed. It's a scientific fact - more comfortable is faster.
CAPACITY: The Roubaix pioneered endurance geometry so you ride "IN" the bike, not "ON" the bike to take the pressure off your hands, arms and shoulders for confidence on any road - and it's ready to tackle a fast-paced mountain descent. Strap in!
With capacity for up to 38c/40mm tires, this Gran Fondo road machine delivers better traction than ever on rough trails and even light gravel. Thanks to their lightweight, efficient Specialized tires deliver extra volume and increased traction without compromising performance.
The Roubaix inspires us to plan some really BIG days on the bike, so we've given it all the mounts your adventures could need: three bottle cage mounts, top tube mounts and it's even fender ready. So go ahead and take it all with you.
PERFORMANCE: The new Roubaix SL8 is our most aerodynamic frame yet, featuring new aero shapes drawn from our Free Foil library and dropped seatstays. At just 825 grams, the frame is 50 grams lighter thanks to lessons learned from the Aethos – the world’s lightest production frame – and our premium Fact 12r carbon fibre. Nothing in its category is faster or lighter than the Roubaix.
