Specialized ROUBAIX SPORT 105 – The Ultimate Endurance Road Bike
Two decades ago, Specialized created the endurance road category, proving that comfort enhances performance. Now, the Roubaix SL8 Sport 105 takes endurance riding to new heights—lighter, faster, and smoother than ever before.
With Future Shock 3.0, an ultra-light carbon frame, and endurance-focused geometry, this bike delivers maximum control, efficiency, and speed on rough roads, long rides, and even light gravel adventures.
Future Shock 3.0 – Maximum Compliance & Control
The Roubaix SL8 Sport 105 features Future Shock 3.0, which provides:
20mm of smooth, stiction-free travel between the stem and head tube, ensuring better shock absorption and handling.
Tunable and adjustable suspension, allowing riders to adapt to various road conditions.
Enhanced control and reduced fatigue, keeping hands and bars stable for a faster, safer, and more comfortable ride.
Paired with the Pavé seatpost and AfterShock technology, the Roubaix SL8 achieves exceptional compliance while maintaining power transfer and efficiency.
Ride Science testing confirms:
✅ 53% less impact at the bars and saddle compared to competitors.
✅ Better speed retention on rough terrain.
✅ Less deflection on impact, ensuring smoother, more efficient riding.
