Review NOLEEN Proflex 856 857 Rear Shock Mtb 7.375 Inch Coil Spring 1.125 Travel

The **Noleen NR1-S ProFlex 856/857 Rear Shock** is a high-performance, coil-spring suspension designed to deliver exceptional comfort, control, and durability for serious mountain bikers seeking a balance between responsiveness and long-lasting performance. Engineered with Noleen s signature **ProFlex** technology, this shock combines a **7.375-inch coil spring** with a **1.125-inch travel** to provide a smooth, progressive feel that absorbs rough terrain while maintaining precise feedback for aggressive riding. The **856/857** model series incorporates a **dual-rate spring system**, allowing riders to fine-tune the shock s stiffness for varying conditions whether tackling steep descents, technical singletrack, or rough trail sections. The **coil-over design** ensures consistent performance under heavy loads, making it ideal for riders who demand reliability in demanding environments.

At the heart of this shock is Noleen s **adjustable rebound and compression damping**, which allows for precise tuning to match rider weight, skill level, and terrain preferences. The **ProFlex linkage system** enhances efficiency by optimizing the shock s travel, reducing bottoming out while maintaining a smooth, linear feel throughout the stroke. The **7.375-inch coil spring** is precision-wound to provide a balanced blend of support and compliance, absorbing impacts without sacrificing responsiveness, while the **1.125-inch travel** ensures the shock remains effective on both moderate and aggressive trails. The **NR1-S** variant also features **Noleen s exclusive ProFlex pivot system**, which minimizes friction and wear, extending the shock s lifespan while improving overall performance.

Built to withstand the rigors of off-road riding, this shock is constructed with **high-grade steel components**, including a **durable coil spring housing** and **reinforced linkages**, ensuring longevity even under extreme conditions. The **adjustable preload** allows riders to fine-tune the shock s stiffness, making it adaptable to different riding styles whether seeking a softer, plush feel for rough terrain or a firmer setup for faster descents. Additionally, the **sealed cartridge system** protects internal components from dirt and debris, reducing maintenance requirements and ensuring consistent performance over time. Whether used on cross-country, enduro, or downhill bikes, the **Noleen NR1-S ProFlex 856/857** delivers a harmonious blend of power, control, and durability, making it a standout choice for riders who demand nothing less than excellence from their suspension.

### **Pros and Cons of buying a Noelen NR1-S ProFlex 856/857 Rear Shock (7.375" Coil Spring, 1.125" Travel)**

The Noelen NR1-S ProFlex 856/857 rear shock is a high-end coil spring shock designed for aggressive mountain biking, enduro, and downhill disciplines. Its key advantages include:

1. **Durability and Build Quality**

- Constructed with high-grade materials, including a forged aluminum frame and a robust coil spring system, ensuring longevity even under extreme conditions.

- The ProFlex design incorporates a progressive linkage system that enhances stability and control, reducing bottoming out and improving ride feel.

2. **Adjustability and Tuning Options**

- Features a **7.375" coil spring** with a **1.125" travel**, making it suitable for riders seeking a balance between comfort and responsiveness for aggressive riding.

- Adjustable rebound damping allows fine-tuning of the shock s response, which is crucial for adapting to different terrains and rider weights.

- Some models include **adjustable preload** (via spring compression), enabling riders to optimize sag and stiffness for their specific needs.

3. **Performance in Rough Terrain**

- The coil spring design provides a firmer, more consistent feel compared to air shocks, which can be sensitive to temperature and pressure fluctuations.

- The ProFlex linkage reduces "chatter" and improves efficiency, making it ideal for technical descents, jumps, and rough trails.

- Better energy return compared to traditional coil shocks, enhancing pedal efficiency and ride feel.

4. **Reliability in Extreme Conditions**

- Coil shocks are less affected by temperature variations (unlike air shocks), making them more reliable in hot or cold environments.

- Lower maintenance requirements compared to air shocks, as they do not require frequent pressure adjustments or leak checks.

5. **Brand Reputation**

- Noelen is a well-respected brand in the MTB suspension industry, known for producing high-performance shocks for professional and competitive riders.

- The NR1-S series is often favored by riders who prioritize durability and consistent performance over adjustable air suspension.

---

1. **Weight**

- Coil shocks are inherently heavier than air shocks due to the spring and frame construction. This added weight can slightly reduce pedal efficiency and maneuverability, though the difference is often negligible for most riders.

2. **Limited Adjustability Compared to Air Shocks**

- Unlike air shocks, which allow for continuous travel and sag adjustments, coil shocks have fixed travel and preload settings. This can be restrictive for riders who need to fine-tune their suspension for varying conditions.

- The rebound damping is adjustable, but the overall stiffness of the shock is dictated by the spring rate, which may not be as adaptable as an air shock s pressure settings.

3. **Higher Cost**

- High-end coil shocks like the NR1-S ProFlex are expensive, often costing significantly more than mid-range air shocks. The investment may not be justified for casual riders or those on a tight budget.

4. **Less Common in the Market**

- Coil shocks are less popular than air shocks in modern MTB suspension, meaning fewer aftermarket parts, rebuild kits, or service options may be available compared to air shocks.

- Some bike shops may have limited experience servicing coil shocks, potentially increasing repair costs or downtime.

5. **Potential for Sag Issues**

- Coil shocks can sometimes suffer from excessive sag if not properly tuned, leading to a "bottoming out" feel or a sluggish response. This requires careful preload adjustment to optimize performance.

6. **Less Suitable for Lightweight Riders**

- The fixed spring rate may not be ideal for lighter riders, who might benefit from a softer spring or adjustable air suspension to match their weight and riding style.

### **Conclusion and Recommendation**

The **Noelen NR1-S ProFlex 856/857 coil shock (7.375" spring, 1.125" travel)** is an excellent choice for riders who prioritize **durability, consistent performance, and aggressive trail capabilities**. It excels in technical descents, jumps, and rough terrain where a firm yet responsive suspension is desired. The ProFlex linkage and progressive design make it one of the best coil shocks available for high-performance riding.

- Prefer the adjustability of air shocks.

- Ride in varying conditions that require frequent suspension tuning.

- Are on a budget or prioritize weight savings.

- Are lightweight and would benefit from a softer spring.

#### **Who Should Buy It?**

- **Aggressive downhill or enduro riders** who need a reliable, high-performance shock.

- Riders who prefer coil suspension over air for its simplicity and durability.

- Those who prioritize **long-term reliability** and are willing to invest in a premium component.

#### **Who Should Consider Alternatives?**

- Riders who want **adjustable travel and sag** (e.g., Fox DHX2, RockShox Super Deluxe).

- Those who prefer **lighter weight** (air shocks like the Fox Float or RockShox Deluxe).

- Casual or trail riders who don t need extreme performance.

If you re a serious rider who demands **consistency, durability, and aggressive capability** from your rear shock, the Noelen NR1-S ProFlex is a **strong recommendation**. However, if you value **adjustability, weight savings, or versatility**, an air shock may be a better fit. Always pair it with a compatible bike frame and fork for optimal performance.
