Product Description
2026 Specialized Roubaix SL8 Comp Shimano 105 Di2 Road Bike
Endurance Road Bike with Future Shock 3.0 & Shimano 105 Di2
Two decades ago, Specialized created the endurance road category—and with the 2026 Roubaix SL8 Comp, they redefine it once again. Engineered to be lighter, faster, and smoother than ever, the Roubaix SL8 combines cutting-edge compliance with race-ready efficiency. When the road turns rough, the Roubaix turns it into pure confidence.
At the heart of the Roubaix SL8 is the advanced FACT 10R carbon frame paired with Future Shock 3.2, delivering exceptional front-end compliance without compromising steering precision. With clearance for up to 40c tires, a threaded bottom bracket, and Shimano’s 105 Di2 12-speed wireless electronic drivetrain, this bike is built for long-distance endurance, broken pavement, and high-speed comfort.
