Specialized created the endurance road category two decades ago, and the Roubaix SL8 is its lightest, fastest and smoothest yet. Future Shock suspension, the Pavé seatpost and proven endurance geometry combine to give you confidence and speed on any road surface.

The Expert build pairs Shimano Ultegra Di2 with Roval C38 carbon wheels and 32mm Mondo tubeless-ready tyres, with Future Shock 3.2 up front. At 8.17kg (size 56), it's built for big days, rough roads and fast rides.

Smoother Is Faster

Roubaix suspends the rider, not the bike. Future Shock at the front and AfterShock at the rear keep you floating above rough roads, reducing impacts by 53% compared with the nearest competitor.

The wheel moves quickly over bumps while your body stays stable, so you keep your momentum – smoother really is faster.

Pioneering Endurance Geometry

Roubaix's endurance geometry puts you 'in' the bike rather than 'on' it, taking pressure off your hands, arms and shoulders on long rides.

Yet it's still ready to dissect a twisting mountain descent at full gas.

More Clearance, More Capable

With clearance for tyres up to 40mm, the Roubaix SL8 grips better than ever on rough roads and even light gravel.

It has every mount your adventures could need – three bottle mounts, top tube mounts and full mudguard compatibility.

Aero and Light

The Roubaix SL8 is the most aerodynamic Roubaix yet, with new FreeFoil tube shapes and dropped seatstays.

Its FACT 10r frame weighs around 950g, using lessons learned from the Aethos to make it one of the fastest and lightest bikes in its class.
