The 2025 Specialized S-Works Roubaix SL8 Di2 Road Bike is lighter, faster, and smoother than any road bike ever made, unleashing unmatched confidence.

The Roubaix SL8 reduces impacts at the bars and saddle by 53% compared to the nearest competition. With Roubaix’s Future Shock 3.0, the wheel quickly moves over the bump, while rider mass remains stable, maintaining momentum in rough terrain. Typical forks deflect backward on impact, causing a measurable loss in speed. It’s a scientific fact: Smoother is indeed faster. The Roubaix pioneered endurance geometry, so you ride “IN” the bike, not “ON” the bike, to relieve pressure on your hands, arms, and shoulders for capability and confidence on any road, yet it’s ready to dissect a mountain decent at full gas. With tyre clearance up to 40mm, this endurance road machine delivers better traction than ever on rough roads and even light gravel.

As you'd expect from an S-Works bike this version of the Roubaix comes with the best equipment including 12 speed Dura-Ace gearing, Roval Terra CLX II wheels and a 4iiii Precision Pro dual-sided power meter.

Who are Specialized?

Specialized is one of the best-known quality bike brands in the world. Started by a group of riders in 1974. A fact which has guided their decision making ever since.

" Made for riders, by riders."

They strove to make the best quality tires when quality tyres weren't around. When people wanted to ride cruisers in the dirt, they made the first production mountain bike. When roadies wanted to go faster, Specialized doubled down on carbon and built their own wind tunnel.

Bikes like the Allez, Rockhopper and Stumpjumper have developed followings and reputations of their own. Specialized has a reputation for making high-end, high-quality bikes. Specialized bikes always look great with high-quality paint and sensible sizing hel0s you get the right bike each time. If you buy a Specialized bike you can be guaranteed it will do what it is supposed to and will last.
