Specialized Roubaix
The Specialized Roubaix is an endurance bike that got its name from the hardest one-day bike race; the Paris-Roubaix. It has a slightly relaxed frame geometry and wider tire clearance compared to the Tarmac.
Specialized sponsored teams will ride this model for the race instead of their usual Tarmac for its Future Shock suspension system. This technology helps make riding more comfortable when the pros ride across rough cobblestones at 30mph.
There are six models in the Specialized Roubaix lineup based on its groupset setup. It’s also available in S-Works frameset only.
| Model | Frame material | Groupset | Wheelset | Retail price (USD) |
|---|---|---|---|---|
| S-Works Roubaix | FACT 11r carbon | Shimano Dura-Ace Di2 (R9200) | Roval Alpinist CLX | $14,250 |
| Specialized Roubaix Pro | FACT 10r carbon | SRAM Force eTap AXS | Roval Alpinist CL | $8,700 |
| Specialized Roubaix Expert | FACT 10r carbon | Shimano Ultegra Di2 (R8100) | Roval C38 | $8,000 |
| Specialized Roubaix Comp | FACT 10r carbon | SRAM Rival eTap AXS | DT Swiss R470 | $5,200 |
Specialized Roubaix vs others
Trek Domane
Trek Domane
| Name | Description |
|---|---|
| OCLV Carbon | Optimum Compaction, Low Void (OCLV). A carbon fiber technology used in Trek frames. Employs advanced layup techniques and precise carbon compaction to create lightweight, strong frames with a balanced blend of stiffness and compliance. Available in two grades; OCLV 800 and 500. A higher number indicates a higher grade carbon. |
| H1.5 geometry | Trek’s geometry design that strikes a balance between aggressive racing positioning (H1) and rider comfort (H2). H1.5 geometry provides a slightly more relaxed riding position than the racier H1 geometry, making it suitable for a wider range of riders. |
| IsoSpeed Technology | An innovative solution for improving rider comfort on rough surfaces. The IsoSpeed decoupler allows the seat tube to flex independently from the rest of the frame, increasing vertical compliance and smoothing road vibrations. |
| Project One | Trek’s customization program that allows riders to create personalized and unique bikes. With Project One, riders can customize various aspects of their bikes, including frame color, paint scheme, components, drivetrain, wheels, and other details. |
Specialized vs Trek carbon fiber
Specialized FACT Carbon
Specialized FACT (Functional Advanced Composite Technology) is an advanced carbon fiber technology used in high-performance Specialized bicycles. It offers a lightweight yet strong frame construction with precise carbon layup, resulting in optimal strength-to-weight ratio and improved ride quality.
FACT carbon frames are engineered to efficiently transfer power, absorb road vibrations, and provide a comfortable riding experience. With continuous innovation and refinement, FACT Carbon demonstrates Specialized’s commitment to delivering top-notch performance and enhancing the overall cycling experience.
The carbon is available in three grades. The choice between FACT 12r, 11r, or 10r carbon depends on the bike model, your preferences, riding style, and budget.
- Specialized FACT 12r Carbon is the highest-grade carbon used by Specialized. Bikes (S-Works models) with frames made from FACT 12r carbon are the lightest and stiffest in the Specialized line-up. These frames are manufactured using the most advanced techniques and materials.
- Specialized FACT 11r Carbon used to be the highest-grade carbon until the S-Works Tarmac (SL5). Today, it’s the highest-grade carbon for the S-Works Roubaix.
- Specialized FACT 10r Carbon is two steps below 12r in the Specialized carbon hierarchy. While it doesn’t provide quite the same level of weight savings and stiffness as 12r, 10r frames are still very light and stiff, providing a high level of performance. FACT 10r carbon is used in all non S-Works models and is ideal for riders who want a balance of performance and value.
Trek OCLV carbon
The OCLV (Optimum Compaction, Low Void) carbon is a proprietary carbon fiber manufacturing technology developed by Trek.
- Optimum Compaction refers to the heat and pressure applied during the curing process to squeeze out excess resin and ensure that the carbon layers are compacted to the optimal density.
- Low Void refers to the goal of reducing microscopic air pockets or voids that can occur in the carbon fiber and create weaknesses.
One of the key advantages of OCLV carbon is its ability to achieve an optimal balance between stiffness, strength, and weight. Trek engineers carefully tune the carbon layup and utilize varying modulus carbon fibers to create stiff frames in certain areas to maximize power transfer while maintaining compliance in other areas to enhance comfort and ride quality.
The OCLV carbon is available in 800 and 500 series.
- OCLV 800 is the highest-grade carbon fiber used by Trek. The carbon modulus is higher in OCLV 800, making it stiffer and lighter. The manufacturing process is more refined, using more advanced carbon and resins, leading to a bike frame that provides top performance levels for stiffness, weight, and strength. OCLV 800 is used in all models with SLR.
- OCLV 500 is a lower-grade carbon but still offers a high level of performance. It has a slightly lower carbon modulus, meaning it’s a bit less stiff and heavier than OCLV 800. OCLV 800 is used in all models with SL.
It’s worth noting that the different OCLV grades don’t only refer to the material itself, but also to the manufacturing techniques used to form the carbon fiber into bike frames. Higher-grade carbon requires more precise manufacturing techniques to take full advantage of its superior material properties.
Frameset technologies and innovations
Specialized Roubaix and Trek Domane framesets incorporate advanced technologies to enhance their bikes’ performance and ride characteristics.
Here’s an overview of the technologies used in each bike model.
Specialized Roubaix
| Name | Description |
|---|---|
| FACT carbon | Functional Advanced Composite Technology (FACT). A carbon fiber construction method that balances lightweight, stiffness, and compliance in Specialized bike frames. Available in two carbon grades; FACT 11r and 10r. A higher number indicates a higher grade of carbon. S-Works models use the FACT 11r carbon and Specialized Pro and Expert models use the FACT 10r carbon. |
| Future Shock | A suspension system designed for the Roubaix road bike to improve rider comfort and control by absorbing road shocks and vibrations, resulting in a smoother and more efficient ride. Located above the head tube, it offers up to 20mm of vertical travel to absorb road bumps and vibrations, enhancing rider comfort and reducing fatigue on rough terrains. |
| Rider-First Engineered™ | Rider-First Engineered™ is a design philosophy used by Specialized that ensures every frame size delivers the same predictable and responsive ride characteristics. This concept was first introduced with the 2015 Tarmac, and the idea has been incorporated into all models since. Instead of simply scaling frame sizes, Specialized takes into account that riders of different sizes have different weights, which are distributed differently. This means that each frame size experiences different forces. Therefore, each frame size is engineered independently with different carbon layups and tube dimensions, ensuring the optimal balance of rigidity, weight, and responsiveness for each size. In short, no matter what the frame size is, the ride quality and performance remain consistently excellent. |
| Win Tunnel | Specialized utilizes advanced tools and technologies to pursue aerodynamic excellence, such as the Win Tunnel, FreeFoil Shape Library, Computational Fluid Dynamics (CFD), and Data Acquisition (DAQ) system. The goal is to optimize aerodynamic performance by conducting wind tunnel tests, developing new airfoil shapes, simulating fluid flow, and collecting real-world data to improve rider position and enhance overall performance. |
