The 2025 Specialized Roubaix SL8 Pro Endurance Road Bike is lighter, faster and smoother than previous generation Roubiax bikes. Designed to be raced on cobbled classics the Roubaix can more than handle rough UK roads and lanes.

The Roubaix SL8 reduces impacts at the handle bars and saddle by 53% verses the nearest competition. With Roubaix’s Future Shock 3.0 the front wheel quickly moves over the bump, while rider mass remains stable, maintaining momentum in rough terrain. 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 new Roubaix SL8 is the most aero yet, with new aero shapes from Specialized's Free Foil library and dropped seat stays. At just 950 grams, the frame is lighter, utilizing lessons learned from the Aethos - the world’s lightest production frame - and Fact 10r carbon blend. Nothing in its class is faster or lighter than the Roubaix. It also comes with clearance for up to 38c/40mm tyres.

The Roubix SL8 Pro comes with Shimano Ultegra Di2 electronic gearing and Roval Terra CL wheels which use a 33mm deep carbon fibre rim matched to ultra-dependable DT Swiss 350 hubs and laced with DT Swiss Competition Straightpull spokes.

This bike is perfect for

Road riders who want to float over rough roads at speed. This is a light and aero road bike that's more than capable of keeping up on fast group rides.

Key features

  • FACT 10R, Rider First Engineered carbon frame
  • Future Shock 3.3 fork with 20mm compliance
  • Shimano Ultegra Di2 gearing and hydraulic brakes

Guide To Road Bike Gears

If you are buying a road bike one of the big differences between models will be which gears they use. Most manufacturers will make the same bike, using the same frame but putting different gears and wheels on it. So for instance you can buy a Trek Domane AL 2 Disc with Shimano Claris gearing for £975 or get the Trek Domane AL 4 Disc with Tiagra gearing for £1625. They are fundamentally the same bike. One comes with the Shimano Tiagra gears and the other comes with Shimano Claris gears.

In most cases, the bottom of the range gears and top of the range gears will basically work in the same way. The big differences are in the quality of material used and the weight. Top of the range gears will be lighter and smoother to use.

One thing to watch out for when comparing bikes is whether the full groupset is being used. If you are buying a bike that has Shimano 105 gears on it. Shimano makes 105 brakes, gear levers, front and rear derailleurs, cranks, chainrings and bottom brackets. So basically all of the running gear on the bike. Some bike manufacturers will fit the full groupset, others will fit Shimano 105 front and rear derailleurs but use their own brakes and cranks to save a few pounds. So if you are comparing bikes be sure to check how much of the groupset the bike actually uses.

Road Bike Buying Guide

Nothing beats the feeling of effortless speed you get on a road bike. There are lots of reasons to ride a road bike, from the simple joy of it, to racing, long distance challenges, or café rides with friends. Whatever you want to do there will be road bike out there for you.

Men’s and Women’s road bikes

Nearly all manufacturers have stopped making dedicated men’s and women’s bikes. They are now all unisex. What you will see is that on smaller bikes, brands will often fit a wider saddle (generally more female friendly). On larger bikes they will often fit a narrower one (generally more male friendly).

Disc or rim brakes

It is getting increasingly hard to buy new bikes with rim brakes as the industry has almost exclusively switched to discs. The reasons for this are pretty simple. Disc brakes are much, much, more powerful than old rim brake systems so you can stop a lot more easily and safely. Disc brakes also allow much bigger tyres to be fitted which is more comfortable. Older disc brake systems did often suffer from rubbing and squeaking. While this hasn’t been completely fixed yet it is much less common on modern bikes with hydraulic brakes. Mechanical disc brakes can still take a bit of fettling to get them right so go for hydraulic if you can.

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.
