History of Specialized Roubaix
The road bikes of the late 1990’s and early 2000’s were aggressive race bikes that could only fit very narrow tyres. These bikes were good for racing and shorter distances but they lacked comfort and versatility. Specialized noticed this and aimed to create a bike that would provide a smooth ride over longer distances that could facilitate wider tyres.
The Specialized Roubaix is even named after the infamous Paris Roubaix one day road race that takes on gravel and cobblestones. As of 2024 it had the most wins of six, which tells you that Specialized have hit their mark with a bike that is both comfortable, capable on rough terrain, and is supremely efficient also.
Key Events in the Development of Specialized Roubaix
In 2008, Specialized signed Tom Boonen and the Quick-Step team who worked with Specialized to create the Roubaix SL2 to: 1) improve the stiffness for better efficiency and vastly improve handling and 2) to do this and still maintain optimal vertical compliance for a comfortable ride quality. Following these improvements, Tom, and Specialized, took home Paris Roubaix wins in 2008 and 2009 and created the Specialized Roubaix we know today – fast and comfortable with supreme handling.
In 2010, Specialized created the Roubaix SL3 that used the brand-new superlight frame technology of the Specialized Tarmac SL3 race bike but with the proven endurance geometry of the Roubaix. Fabian Cancellara won Paris Roubaix on what was the Roubaix SL3’s debut.
The next major innovation for the Roubaix came in 2017 with the introduction of future shock front suspension to improve the comfort even more. The Future Shock system provides 20mm of active suspension above the stem to further smooth out rough roads. Specialized claim that future shock actually improves efficiency. We will go into future shock in more detail later in the article. Following the introduction of future shock, a second place at Paris Roubaix for Zdenek Stybar in 2017, and a win for Peter Sagan in 2018. With the introduction of future shock, Specialized coined the mantra “smoother is faster” to describe exactly what they were aiming to achieve with the Roubaix.
2019 was another big year for the Specialized Roubaix. Aside from the introduction of Future Shock 2.0, Specialized again borrowed from the Tarmac race bike by focusing on improving aerodynamics to make the Specialized Roubaix even faster while maintaining the compliance and comfort.
2025/2026 introduced the latest in Future Shock technology with the release of the 3.1, 3.2, and 3.3 versions. More about this later in the article.
First Hand Experience
As a very keen road cyclist myself, I was excited when I was offered the chance to try the new Specialized Roubaix Expert SL8, especially as I have always ridden road race bikes and am used to their geometry and efficiency. It meant I was well placed to give my verdict of whether Specialized’s ‘smoother is faster’ claim was warranted.
When first riding the Specialized Roubaix, the first thing you notice is how comfortable it is. The future shock front suspension really does smooth out even rough Edinburgh roads and the wider tyres give a high degree of confidence even in the wet. The frame itself does a great job of smoothing out the road buzz on the rear end with help from the specifically designed Pave seatpost. I can confirm that from the comfort side of things, Specialized really were not over exaggerating how comfortable this bike is.
In road cycling, you would tend to expect that more comfort and an upright geometry would be to the detriment of the efficiency so I was keen to see if the Specialized Roubaix felt similar to my current road race bike in terms of efficiency and handling.
I am happy to report that the bike felt really responsive to putting the power down and felt effortless to keep at high speed which demonstrates the quality of the frame. I, of course, did not have all the fancy testing at my disposal so I cannot produce numbers but my feel is that the Roubaix Expert efficiency feels very close to my current road race bike.
The gap is so narrow between the Roubaix and my current race bike, if I were in the market, I would probably buy the Specialized Roubaix in future as the extra comfort is more than worth it with very little, or no, reduction in efficiency.
Technical Specifications
There is a lot to look at when it comes to Specialized Roubaix and the differences across the range. We will have a look at the frames, frame material, wheels, the latest future shock, and maximum tyre clearance.
The Frames
The Specialized Roubaix frame features endurance geometry for a more upright and less stretched-out seating position. This shape lends itself to more comfort over longer distances by reducing fatigue and the pressure on touch points such as the hands and feet. Specialized claim that reduced fatigue leads to more efficiency and increasing the distances possible. Over the years, the Roubaix frame has borrowed from the Specialized Tarmac race bike by first utilising the superlight frame technology and later the aerodynamic properties to increase speed.
Aside from the comfort, the quality carbon frame increases efficiency by increasing power transfer from your legs and the bike. A great endurance frame will built compliance to give comfort but also build in stiffness where needed for the bike to be incredibly efficient. This is why you find carbon on most higher end road bikes – carbon can be manipulated to give compliance and stiffness where required.
The Specialized Roubaix blurs the line between all of the main road bike types – Endurance, aerodynamic, and climbers race bikes. And honestly, they do it incredibly well.
Frame Material
All of the Roubaix SL8 bikes feature Specialized FACT carbon composite. Carbon is used due to the ability to make it stiff in certain sections for improved efficiency while making it compliant in others for increased comfort.
Specialized use the FACT 10r carbon on all models of Roubaix except the S-Works Roubaix which gets the added efficiency of the 12r carbon.
Wheels
As you go up through the range of Specialized Roubaix, the specifications of the bikes changes and you will get improving quality with the more you spend. The lower models have Aluminium alloy wheels while the higher models will get carbon wheels. Alloy wheels keep the price down while still being strong and robust whereas carbon wheels reduce weight, improve handling and also aid in acceleration. The SL8 range is as follows.
- Base Model: Specialized Roubaix SL8 Sport – DT Swiss Aluminium Alloy
- Specialized Roubaix SL8 Comp – DT Swiss Aluminium Alloy
- Specialized Roubaix SL8 Expert – Roval Terra C Carbon
- Specialized Roubaix SL8 Pro – Roval Rapide CL III Carbon
- S-Works Roubaix SL8 – Roval Terra CLX II Carbon rims
*Roval wheels are designed by Specialized themselves.
Future Shock
The innovative Future shock was first introduced to the Specialized Roubaix in 2017. It features 20mm of active travel suspension that sits above the headset. As well as the significantly increased comfort, Specialized claim that having the travel above the headset keeps the tyres in contact with the ground more leading to more efficiency and more confidence inspiring handling. The Future Shock is key to the Roubaix’s “smoother is faster” mantra.
Here is how Specialized describe it –
“The Future Shock features up to 20mm of travel, and it’s positioned above the head tube in order to move in a vertical path. So when the front wheel encounters rough terrain, the bike moves up towards your hands and preserves your forward momentum without slowing you down. Another important fact is that, because the Future Shock is positioned above the stem, the bike’s wheels are held together rigidly by the frame. In other words, because the wheelbase isn’t changing throughout the suspension’s travel, like with traditional system, you get the added benefit of extremely predictable handling.” – Specialized.com
Specialized are currently in their third iteration and are currently running Future Shock 3 with a 3.1, 3.2, and 3.3 version.
Future Shock 3.1
The Future Shock 3.1 is spring loaded with no on the fly adjustability. You are able to adjust the feel of the travel at home by replacing one of three springs for a soft feel, medium feel and stiff feel.
Future Shock 3.2
The second level up, Future Shock 3.2 uses hydraulic damping and has no on the fly adjustability.
Future Shock 3.3
The top of the line Future Shock 3.3 features the same hydraulic damping as the 3.2 but features a dial on the top for on the fly adjustment while you are out on a ride.
Tyres
Classic, older road bikes could only fit narrow tyres that were notoriously uncomfortable. This was one of the factors that Specialized looked to solve by creating the Roubaix. The latest round of Roubaix SL8’s come with a 32mm wide tyre with the ability to fit up to 40mm, a size more commonly found on gravel bikes. The ability to change the tyre size gives the rider the ability to increase the comfort or the loose surface traction even further.
For more gravel rides, you could even fit a Specialized Pathfinder TLR tyre.
Verdict
In 2004, Specialized set out to fill a gap in the market by creating the unthinkable… a supremely comfortable road bike that was as efficient and manoeuvrable as a race bike. They have come good on their promise. The Specialized Roubaix offers unparalleled comfort while still being incredibly efficient and handling brilliantly.
If you are looking for a road bike that you can ride all day and still be fast doing it then the Specialized Roubaix is for you. With many different models in the range, you will find one at a price point and spec for you.
Frequently Asked Questions
We searched the internet for the most frequently asked questions about the Specialized Roubaix endurance road bike so we are going to answer them for you.
What makes the Specialized Roubaix a Good Choice for UK road conditions?
The UK is notorious for rough roads so the Specialized Roubaix is an excellent choice for riding here. The reasons for this comfort are fourfold –
- The Frame – The incredible carbon frame has compliance built in to smooth over rough surfaces but still builds in stiffness where it matters to keep the excellent efficiency. The seatpost is also designed to work with the frame to minimise road buzz on even the roughest tarmac.
- The Future Shock – The 20mm of active suspension above the headset takes the sting out of poor quality roads (of which the UK is famous unfortunately) while adding to efficiency by keeping the front wheel in contact with the ground more consistently when the roads are bumpy.
- The Tyres (and tyre clearance) – Having wider tyres and therefore more air between you and the road only adds to the amazing comfort on offer on the Roubaix. 32mm wide tyres give great comfort off the peg but you can fit up to 40mm wide tyres if you want to increase the comfort further.
- Mudguard mounts – Many modern endurance bikes are coming with mudguard mounts so you can fit fenders if you would like some protection from the rain (another thing the UK is famous for). Mudguards are an excellent option to protect your clothes and especially your bike in the fringe seasons of autumn and spring.
So yeah, the Roubaix is a brilliant choice for riding in the UK.
Can Specialized Roubaix handle both paved roads and gravel tracks?
The first part of this question is easy – yes, the Roubaix doesn’t just handle paved roads, it thrives on them. As for gravel tracks, it’s still a yes but it would probably be light gravel and as a personal recommendation, if you find yourself on light gravel a lot, you might want to coat your frame in some protection to prevent loose stones and debris hitting and damaged your lovely frame.
If you fancy turning the Roubaix into more of a gravel bike, you can fit this with wider tyres to improve gravel grip.
What are the differences between the Specialized Roubaix models available in the UK?
There are currently 7 models of the latest Roubaix SL8 available. There are the Roubaix, Roubaix Sport, Roubaix Comp, Roubaix Expert, Roubaix Pro and the S-Works Roubaix. We cover the main specs here but we have let out finishing kit because then this would be a very long answer. Here are more the details of the different models…
Roubaix
The entry model Roubaix features the 10r carbon frame and Future Shock 3.1 for 20mm active travel suspension. The groupset is the reliable and robust Shimano Tiagra with the Shimano Tiagra hydraulic disc brakes. Finished off with Axis Elite Disc alloy wheels.
Roubaix Sport
The Roubaix Sport features the same frame and Future Shock 3.1 as the base model above. The differences come in the wheelset, brakes, and groupset.
The wheelset are the robust and reliable DT Swiss alloy wheels that are lighter and more efficient than the wheels on the base Roubaix.
On the Roubaix Sport, you have a choice of two different models with either SRAM or Shimano. The SRAM version comes with 1 x 12 speed SRAM Apex XPLR AXS wireless electrionic shifting and SRAM Apex hydraulic disc brakes. The 1 x gearing is more suited to more gravel style cycling as you have the low end for climbing but lose a bit of the downhill gearing.
The Shimano version of the Roubaix Sport comes with the smooth and efficient Shimano 105 2 x 12 speed mechanical gearing, and Shimano 105 hydraulic disc brakes. This model costs less than the SRAM version as these gears are mechanical.
Roubaix Comp
The Roubaix Comp has the same carbon frame as the previous two models but gets an upgrade of the Future Shock to the 3.2 version. You again get the DT Swiss alloy wheelset but you get an upgrade to the Shimano 105 Di2 2 x 12 speed electronic shifting and the Shimano hydraulic disc brakes.
Roubaix Expert
Another version with the 10r carbon frame and Future Shock 3.2 as the above bikes but you get some significant upgrades on the Expert. For a start you get Roval Terra carbon wheels for added efficiency and handling, and the groupset is the exceptional SRAM Rival eTap AXS 2 x 12 wireless electronic shifting, and the brakes are SRAM Rival hydraulic disc brakes.
Roubaix Pro
An upgrade here to the lockable Future Shock 3.3 and some other spec upgrades too. You get the higher quality carbon wheels with Shimano Ultegra Di2 2 x 12 electronic shifting with the incredible Shimano Ultegra hydraulic disc brakes.
S-Works Roubaix
The top-of-the-line Roubaix is kitted out as extravagantly as the £12000 price tag suggests. The best 12r carbon frame for more efficiency while also featuring the best carbon wheels Specialized produce. You also have a choice of either the best groupsets from either Shimano or SRAM. The Shimano versions comes with the sublime Dura Ace Di2 2 x 12 electronic groupset and Dura Ace hydraulic disc brakes. The SRAM version comes with their awe-inspiring SRAM Red AXS eTap 2 x 12 wireless electronic shifting and SRAM Red hydraulic disc brakes. SRAM Red is a level above the SRAM Force AXS groupset.
Is the Specialized Roubaix suitable for long distance cycling events and daily commuting?
Another double part question where the first part is easy… yes, the Roubaix is exceptional for long-distance cycling events due to the comfort offered from the frame, tyres and Future Shock. Another factor that improves comfort on long-distance cycles is the pioneering endurance geometry that has riders in a more upright and less stretched out position.
The second part of this question is probably more personal preference than anything else. Yes, the Roubaix would handle daily commuting if you popped some mudguards on it but we would maybe argue that this is like taking a Ferrari to the shops… a bit overkill and too nice a bike to wear out the components of for a commute. But like we say, by all means use it for the commute if you like and one thing is for sure – you will get to work and back in supreme comfort.
What tyre size can I fit on the Specialized Roubaix and how does this affect performance?
The Specialized Roubaix comes fitted with 32mm tyres off the peg but you can fit up to 40mm (without mudguards). The effect on performance with wider tyres would be to give you better grip on loose surfaces while giving you more comfort on your ride.
Are there any special maintenance needs for the Future Shock?
There is actually very little maintenance required on the new Future Shocks. Specialized advise that the Future Shock is designed to offer consistent performance for the life of the product. Due to its fully sealed design, the Future Shock assembly does not need service beyond wiping dirt and dust from the exterior.
They also go on to advise that should the rubber boot become fatigued over time, replacements can be ordered.
How does the Specialized Roubaix perform in wet and muddy conditions that are common in the UK?
The internet is loving a two part question today. For the first question about the wet; The Roubaix is incredible in the wet due to the wider tyres and powerful hydraulic disc brakes as standard. The rain does not affect the stopping power of hydraulic disc brakes so you can have confidence stopping on all conditions. Wider tyres will also give more grip it wet conditions.
As for the mud; we would recommend fitting a wider, more gravel style of tyre to give more grip in this type of weather although if you are wanting to ride in mud a lot, you might want to consider a Specialized Diverge instead.
