Review ROCKSHOX Super Deluxe Select Air Rear Shock 250mm 70mm Mtb Aluminum

The **RockShox 25 Deluxe Select Air Rear Shock** (part number **25T40945714**) is a high-performance, all-terrain suspension component designed to elevate the riding experience on mountain bikes across a wide spectrum of disciplines, from aggressive downhill and enduro to technical trail and cross-country. Engineered with RockShox s signature precision and durability, this shock delivers a seamless blend of responsiveness, comfort, and control, making it an ideal choice for riders seeking a balance between performance and versatility. The **25mm stanchion diameter** provides a robust yet lightweight construction, ensuring minimal weight transfer while maintaining structural integrity under extreme loads, whether tackling steep descents or absorbing the jarring impacts of rocky descents. With a **70mm travel**, this shock excels in absorbing large bumps and maintaining traction, allowing riders to push harder without sacrificing comfort or stability. The **Select Air** tuning system offers riders the flexibility to fine-tune their suspension to match their weight, riding style, and terrain preferences, with adjustable preload and rebound damping to dial in the perfect feel for everything from fast-flowing singletrack to rough, technical descents.

At the heart of the 25 Deluxe Select Air is RockShox s **AirSpring technology**, which combines a sealed air chamber with a progressive coil spring to deliver a smooth, predictable ride feel. The **Select Air** system allows for precise adjustments to the shock s stiffness, enabling riders to optimize performance for their specific needs whether it s a firmer setup for aggressive downhill riding or a softer, more forgiving feel for long-distance cross-country adventures. The **dual-path rebound damping** ensures consistent performance across a wide range of conditions, while the **low-speed compression** is finely tuned to handle small, frequent bumps without bottoming out, even on the roughest terrain. The **Deluxe** build quality further enhances reliability, featuring a durable **anodized aluminum fork crown** and **high-strength steel components** that are designed to withstand the rigors of intense riding sessions.

One of the standout features of the 25 Deluxe Select Air is its **adjustable rebound damping**, which allows riders to fine-tune the shock s response to their pedaling cadence and riding style. This ensures that the suspension remains efficient and responsive, whether you're pedaling aggressively uphill or carving through tight corners on the descent. The **preload adjustment** is equally intuitive, enabling riders to dial in the perfect sag for their weight and riding preferences, which is crucial for maintaining optimal suspension performance and wheel contact. Additionally, the shock s **low-speed compression** is engineered to handle small, high-frequency bumps smoothly, reducing fatigue and improving control on technical terrain. The **high-speed compression** is equally robust, ensuring that the shock remains stable under heavy loads during aggressive descents or when hitting large jumps.

The **25 Deluxe Select Air** is not just a high-performance shock; it s a versatile tool that adapts to the demands of modern mountain biking. Whether you're a competitive enduro rider looking to shave seconds off your lap times or a trail enthusiast seeking a smooth, controlled ride through varied terrain, this shock delivers the precision and reliability needed to push your limits. Its **durable construction** and **sophisticated tuning options** make it a standout choice for riders who demand the best in both performance and adaptability. With RockShox s reputation for innovation and quality, the 25 Deluxe Select Air is more than just a component it s a performance-enhancing upgrade that transforms the way you ride, ensuring that every descent, every climb, and every corner is met with confidence and control.

The **RockShox 25T40945714 Deluxe Select Air** is a mid-range rear shock designed for mountain biking, offering a balance of performance, adjustability, and affordability. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Adjustable Air Spring**

- The air-sprung design allows for precise sag and stiffness adjustments, enabling riders to fine-tune the shock s performance to their weight, riding style, and terrain. This is particularly useful for riders who frequently switch between different bikes or conditions.

2. **Select Air Valve**

- The Select Air valve system provides easy, dial-in adjustments for rebound and compression damping. This makes it accessible for riders who want to tweak their suspension without needing specialized tools or expertise.

3. **Mid-Range Performance**

- Positioned above entry-level shocks like the RockShox Recon or Fox DHX, the Deluxe Select Air offers better damping quality and durability than budget options. It handles moderate trail riding, cross-country, and light enduro use effectively.

4. **Durability**

- RockShox s reputation for reliability means this shock is built to last through years of use, especially if maintained properly. The materials and construction are robust enough for regular trail riding and light to moderate abuse.

5. **Compatibility**

- The 25mm stanchion size is common on many mid-range and high-end MTBs, making it a versatile choice for riders who may want to upgrade or replace shocks in the future.

6. **Cost-Effective**

- Compared to premium shocks like RockShox s Boxxer or Fox s Float DP, the Deluxe Select Air offers a significant price drop while still delivering solid performance. It s a practical choice for riders who want better suspension without breaking the bank.

7. **Low Maintenance**

- The air-sprung system reduces the need for frequent oil changes or internal adjustments compared to coil-sprung shocks. The Select Air valve also simplifies damping adjustments, making maintenance easier.

8. **Good for Versatile Riding**

- The shock s adjustability makes it suitable for a range of disciplines, including cross-country, trail riding, and light enduro. Riders who switch between different types of terrain will appreciate its adaptability.

---

### **Cons**

1. **Not for Extreme Use**

- While capable of handling moderate abuse, this shock is not designed for heavy-duty enduro, downhill, or freeride riding. The damping and build quality may struggle under extreme loads, leading to premature wear or failure.

2. **Limited Damping Quality**

- Compared to higher-end shocks like RockShox s Boxxer or Fox s Float, the Deluxe Select Air has less sophisticated damping technology. This can result in less smooth performance on rough terrain or at high speeds, where more advanced shocks excel.

3. **Weight**

- Like most air-sprung shocks, the Deluxe Select Air is heavier than coil-sprung alternatives. While not overly cumbersome, this can slightly impact the bike s handling, especially in cross-country riding where weight matters.

4. **Air Spring Limitations**

- Air springs can be less consistent in performance compared to coil springs, especially in extreme temperatures. Cold weather may require adjustments to maintain optimal sag, and hot weather can lead to over-inflation if not monitored.

5. **Build Quality Relative to Premium Shocks**

- While durable, the materials and construction are not as high-end as those found in RockShox s Boxxer or Fox s Float shocks. This means it may not handle the same level of punishment or last as long under extreme conditions.

6. **No Remote Reservoir (On Some Models)**

- Depending on the specific model year or variant, some versions of the Deluxe Select Air may not include a remote reservoir, which can limit the shock s ability to handle high-speed impacts or aggressive riding styles.

7. **Learning Curve for Adjustments**

- The Select Air valve system is user-friendly, but riders new to suspension tuning may need some time to understand how to dial in the rebound and compression settings for optimal performance.

---

### **Conclusion**

The **RockShox 25T40945714 Deluxe Select Air** is an excellent choice for riders seeking a mid-range, adjustable rear shock that balances performance, adjustability, and affordability. It excels in versatility, making it suitable for cross-country, trail riding, and light enduro use. Its air-sprung design and Select Air valve provide easy customization, while its durability ensures reliable performance over time.

However, it is not ideal for extreme or heavy-duty riding, where more advanced shocks would be better suited. Riders who prioritize smoothness, high-speed handling, or aggressive trail use may find that higher-end shocks offer superior performance. That said, for the majority of recreational and mid-level mountain bikers, this shock delivers solid value and a great riding experience.

---

### **Recommendation**

- You are a rider who enjoys cross-country, trail riding, or light enduro and want an adjustable, mid-range shock.

- You value ease of use and the ability to fine-tune your suspension without needing professional help.

- You are looking for a cost-effective upgrade from entry-level shocks and want better performance without spending top-tier prices.

- Your riding style is moderate, and you do not frequently push the limits of your bike s suspension.

- You ride heavily in enduro, downhill, or freeride disciplines where extreme loads and high-speed impacts are common.

- You prioritize the smoothest possible performance and are willing to invest in a higher-end shock for better damping quality.

- You frequently ride in extreme temperatures where air-sprung shocks may require constant adjustments to maintain optimal performance.

- You are looking for a shock with advanced features like a remote reservoir or more sophisticated damping technology.

For most riders who fall into the first category, the Deluxe Select Air is a smart purchase that offers a great blend of performance and value. If you are unsure about your riding demands, consider testing it on your bike or borrowing one from a friend to see if it meets your needs before committing to a purchase.
