The 2026 Specialized Roubaix SL8 Comp Endurance Road Bike is lighter, faster, and smoother than any road bike Specialized have ever made. The road may be hell below, but on Roubaix, it's always heaven above. The Comp is a mid-range model that comes with solid and dependable kit.

Future Shock 3.0 is the star of the show, more tuneable, adjustable, and durable than ever. Now, regardless of position on the bike, every rider experiences 20mm of smooth, stiction-free travel between the stem and head tube. Future Shock helps keep your hands and bars steady for a smoother ride with more control to stay fast, safe, and confident. The dropped clamp design exposes more seatpost to increase deflection, but “more” isn’t simply better. The Pavé seatpost controls that deflection for the optimal vertical compliance. Together they create AfterShock technology, and when paired with the Roubaix’s rigid rear triangle, deliver a smooth ride with no loss in efficiency.

The Roubaix SL8 Comp comes with ultra reliable 12 speed Shimano 105 Di2 gearing and solid DT Swiss G540 gravel wheels. With tyre clearance up to 40mm, this endurance road machine delivers better traction than ever on rough roads and even light gravel. Thanks to lightweight, super-efficient Specialized tires, that extra tyre volume and traction comes with no downsides.

This bike is perfect for

The Roubaix is designed for racing over Belgian cobbles so can handle rough UK country lanes with ease. Working from the premise that smooth is fast you'll be cruising on your next club ride or sportive.

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.
