Roubaix SL8 Sport - Shimano 105
Smoother is faster. The endurance road bike we invented, refined again.
Specialized created the endurance road category two decades ago, proving that high ergonomics means high performance. Today the Roubaix SL8 with Future Shock is lighter, faster and smoother than any road bike before it. The road may be hell below, but on the Roubaix it's always heaven above.
Best for: Long road days, rough Australian tarmac and riders who want speed without being beaten up by the surface.

Key highlights
Future Shock 3.2 gives every rider 20mm of smooth, stiction-free travel between the stem and head tube, keeping hands and bars steady for more control.
The dropped seat clamp exposes more seatpost to increase deflection, and the S-Works Pave seatpost controls that deflection for optimal vertical compliance - together, AfterShock technology.
FACT 10R Rider First Engineered carbon frame with FreeFoil Shape Library tubing, tuned so every frame size rides the same.
Shimano 105 12-speed with hydraulic disc brakes throughout, on tubeless-ready DT Swiss G540 wheels.
