Roubaix SL8 Sport - Shimano 105
Smoother is faster
We 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 we've ever made, delivering unmatched confidence on rough roads.
Best for: Endurance road riding, long days in the saddle and rougher sealed roads.

Key highlights
Smooth, stiction-free travel between the stem and head tube smooths out road buzz and keeps your hands and bars steady on rough surfaces.
The lightest Roubaix frame yet, built using lessons learned from the Aethos platform without giving up any of the model's signature comfort.
A dropped clamp design and S-Works Pavé seatpost work with Future Shock to soak up impacts at both ends of the bike, with no loss in pedalling efficiency.
Reliable 12-speed shifting and braking with a wide-range 50/34t crank and 11-36t cassette for climbing comfortably on long days.
