Review ROCKSHOX Super Deluxe Ultimate Rear Shock 190x45mm Air High performance

The **RockShox 00.4118.454.010 Deluxe Ultimate RC2T Rear Shock** is a cutting-edge, high-performance suspension component designed to redefine the boundaries of off-road capability, precision, and rider control. Engineered for the most demanding trails, aggressive riders, and high-speed descents, this shock stands as a testament to RockShox s relentless innovation in suspension technology. At its core, the **Deluxe Ultimate RC2T** features RockShox s proprietary **Remote Control Technology (RC2T)**, a system that seamlessly integrates with the **RockShox AfterShock app**, allowing riders to fine-tune suspension settings on the fly with unprecedented precision. Whether adjusting sag, rebound, or compression damping, the app provides real-time feedback and customization, ensuring the shock adapts instantly to varying terrain, rider weight, and riding style eliminating the need for manual adjustments mid-ride.

Built with a **190mm travel** and a **45mm air canister**, this shock delivers a perfect balance of extension and compression performance, making it ideal for riders seeking both plush, absorbing impacts on rough terrain and responsive, snappy handling for technical climbs and aggressive descents. The **Deluxe Ultimate** variant elevates this further with RockShox s **Deluxe** technology, which incorporates a **high-performance air spring** for optimized tuning, reduced internal friction, and enhanced durability. The **RC2T** system itself is a game-changer, utilizing a **remote-controlled valve** that adjusts damping characteristics dynamically, adapting to the demands of the ride in real time. This eliminates the guesswork of traditional shock tuning, allowing riders to dial in their setup with confidence, whether they re tackling a fast, technical downhill or cruising through a mix of singletrack and jumps.

Constructed with **high-grade aluminum and reinforced steel components**, the **00.4118.454.010** is built to withstand the harshest conditions, from deep sand and mud to rocky descents and repeated high-impact landings. The **air spring** is sealed with RockShox s **high-performance O-rings and seals**, ensuring longevity and consistent performance even under extreme stress. The **Deluxe Ultimate** variant also includes **low-friction bearings** and a **smooth, linear piston design**, reducing energy loss and improving efficiency, which translates to better traction, control, and rider feedback. The **45mm air canister** is not only compact but also highly efficient, allowing for precise tuning without sacrificing performance or adding unnecessary bulk to the bike.

For riders who demand the ultimate in adjustability and performance, the **RC2T** system is a standout feature, offering **three distinct damping modes** (Soft, Medium, Hard) that can be switched instantly via the app or a remote control. This level of customization ensures that the shock can be optimized for everything from leisurely trail rides to competitive downhill racing. Additionally, the **Deluxe Ultimate** variant includes **RockShox s proprietary rebound damping**, which enhances pedal efficiency and control, making climbs smoother and descents more manageable. The shock s **sag adjustment** is also finely tuned, allowing riders to dial in the perfect balance between comfort and responsiveness, whether they prefer a softer, more forgiving setup or a firmer, more aggressive feel.

In summary, the **RockShox 00.4118.454.010 Deluxe Ultimate RC2T Rear Shock** is a pinnacle of modern suspension engineering, combining **190mm of high-performance travel**, **RC2T s dynamic damping control**, and **Deluxe s precision tuning** into a single, ultra-capable component. Whether you're pushing the limits on a high-speed descent, navigating technical singletrack, or simply seeking the smoothest, most responsive ride possible, this shock delivers unmatched performance, adaptability, and durability. It s not just an upgrade it s a revolution in how riders interact with their suspension, making every trail feel more connected, controlled, and exhilarating.

### **RockShox 00.4118.454.010 Deluxe Ultimate RC2T Rear Shock (190x45mm) Pros and Cons**

#### **Pros**

1. **High-Performance Suspension** The RC2T (Reaction Chain Technology) is RockShox s most advanced air suspension system, offering superior damping and responsiveness compared to older models. It uses a dual-chamber design with separate compression and rebound chambers, allowing for precise tuning.

2. **Adjustable Preload and Sag** The air spring allows for fine-tuned sag adjustment, which is crucial for optimizing comfort and performance based on rider weight and riding style. This makes it versatile for different disciplines (trail, enduro, downhill).

3. **High-Speed Stability** The RC2T s advanced damping technology helps maintain stability at high speeds, reducing dive and squat under heavy braking or aggressive riding. This is particularly beneficial for downhill and freeride applications.

4. **Durability and Build Quality** RockShox is known for robust construction, and the Deluxe Ultimate line is built to withstand heavy use. The 190mm travel is well-suited for modern full-suspension bikes, offering a good balance between comfort and performance.

5. **Compatibility with RockShox Systems** If you already have RockShox components (e.g., forks, handlebars, or other shocks), this shock integrates seamlessly with their ecosystem, including potential future upgrades.

6. **Wide Range of Adjustments** The shock features multiple damping adjustments (clicker adjustments for compression and rebound) and an air screw for sag tuning, giving riders significant control over feel and performance.

7. **Good for Aggressive Riding** The RC2T s damping is designed to handle aggressive inputs, making it suitable for riders who push their bikes hard on technical or high-speed terrain.

8. **Resale Value** RockShox shocks, especially high-end models like this one, retain value well, making it a practical long-term investment.

#### **Cons**

1. **Expensive** This is a premium shock, and the price reflects its advanced features. It may be overkill for casual or entry-level riders who don t need such high-performance tuning.

2. **Complexity** The extensive adjustability can be overwhelming for beginners. Proper setup requires an understanding of sag, damping, and air pressure, which may necessitate professional help or practice.

3. **Maintenance Requirements** High-performance shocks like the RC2T require regular maintenance, including air spring checks, damping oil changes, and seal inspections. Neglecting maintenance can lead to premature wear or failure.

4. **Weight** While not excessively heavy, the RC2T is heavier than some budget shocks. This may not be a significant issue for most riders, but it s worth noting for those prioritizing minimal weight.

5. **Learning Curve for Setup** Achieving optimal performance requires time and experimentation. Riders may need to adjust sag, damping, and air pressure repeatedly to find the right setup for their weight and riding style.

6. **Potential for Overkill** For riders who mostly do light trail riding or casual cross-country, the advanced features of the RC2T may not be fully utilized, making a more affordable shock a better value.

7. **Compatibility Issues** While generally compatible with most modern full-suspension bikes, there may be specific fitment concerns depending on the bike s frame design or axle standards (e.g., 12x100mm vs. 12x142mm). Always verify compatibility before purchasing.

### **Conclusion**

The **RockShox 00.4118.454.010 Deluxe Ultimate RC2T** is one of the best high-performance rear shocks available, offering unmatched damping technology, adjustability, and durability. It is ideal for riders who demand precision, stability, and customization, particularly those engaged in aggressive trail riding, enduro, or downhill. However, its high cost, complexity, and maintenance requirements make it less suitable for casual riders or those on a tight budget.

If you prioritize performance, control, and long-term reliability and are willing to invest the time and effort into tuning it this shock is an excellent choice. For riders who prefer simplicity or don t need advanced features, a more budget-friendly shock (e.g., RockShox s lower-tier models or alternatives like Fox Float or DT Swiss) may be a better fit.

### **Recommendation**

- **Buy it if:** You ride aggressively, prioritize high-performance suspension, and are willing to invest in tuning and maintenance. It s also a strong choice if you re building a high-end trail, enduro, or downhill bike and want the best rear shock available.

- **Skip it if:** You re a casual rider, on a tight budget, or prefer a simpler setup. In that case, consider a more affordable shock that still offers good performance without the complexity.

- **Consider alternatives:** If you like the RC2T s technology but want to save money, look at the **RockShox Deluxe or Fox Float D** as mid-range options. For maximum performance without the RC2T s price, the **Fox Factory Float D** or **DT Swiss SLR** are also strong contenders.
