The **180mm of travel** strikes an ideal balance between efficiency and control, making it an exceptional choice for riders seeking a versatile fork capable of handling everything from fast-flowing downhill sections to precise, technical climbs. At its core, the Dorado Air IRT 29 leverages **Manitou s proprietary Air IRT (Internal Resistance Technology)** system, a refined evolution of their legendary air-spring technology.

The **adjustable rebound damping** ensures quick recovery after impacts, while the **compression damping** can be fine-tuned to suit everything from aggressive downhill riding to relaxed cross-country pedaling. The fork s **29-inch wheel compatibility** further enhances its versatility, offering improved traction, stability, and rollover clearance ideal for riders who demand the best possible performance on larger wheels without compromising on maneuverability.

Constructed with **high-grade aluminum and carbon fiber components**, the Dorado Air IRT 29 is built to withstand the rigors of extreme riding. The **steel axle** provides robust reinforcement, while the **sealed cartridge bearings** ensure smooth, low-friction operation even after thousands of miles of use. The fork s **low-profile design** and **integrated IRT damping rods** contribute to a clean, aerodynamic look while maintaining optimal ground clearance. Whether you're riding in the dirt, mud, or sand, the Dorado Air IRT 29 s **robust sealing system** and **durable components** keep it performing at its best, even in the harshest conditions. The **Dorado Air IRT app** adds a modern touch, allowing riders to customize their fork s settings via Bluetooth connectivity, ensuring that the suspension always matches the demands of the ride. From the moment you first engage with this fork, you ll notice the difference smoother impacts, better control, and an unmatched sense of connection to the trail, all while pushing the boundaries of what a modern suspension fork can achieve. Perfect for serious enduro riders, downhill enthusiasts, and trail junkies who refuse to compromise on performance, the Manitou Dorado Air IRT 29 is not just a fork it s a game-changer.

### **Pros and Cons of the Manitou Dorado Air IRT 29 Fork (191-35561-A103, 180mm Travel, 20x110 Boost)**

#### **Pros**

1. **High-Quality Construction** The Dorado Air IRT is built with a durable aluminum crown and a robust frame, ensuring longevity and reliability. The internal air spring system provides smooth, consistent performance across a wide range of weights and riding styles.

2. **Adjustable Air Spring** The internal air spring allows for precise sag and stiffness adjustments, making it adaptable to different rider weights (100 200 lbs / 45 90 kg) without needing additional external components. This reduces the need for multiple fork models.

3. **Internal Routing (IRT) Design** The Integrated Routing Technology (IRT) keeps cables and hoses clean and protected, reducing maintenance and improving durability. This is particularly beneficial for riders who frequently ride in muddy or dirty conditions.

4. **180mm Travel** The 180mm travel is well-suited for cross-country (XC) and light trail riding, offering enough compression to handle rough terrain while maintaining efficiency for faster descents. It strikes a good balance between performance and weight.

5. **Boost 20x110 Compatibility** The fork is designed for Boost 148mm hub spacing, which is now the industry standard for modern bikes. This ensures better wheel stability and handling, especially on rough terrain.

6. **Smooth Damping** Manitou s damping technology provides a refined ride quality, with minimal pumpiness and a progressive feel. The air spring helps reduce bottom-outs and improves efficiency, making it suitable for aggressive XC and light trail riding.

7. **Lightweight** While not the lightest fork on the market, the Dorado Air IRT is reasonably lightweight for its class, improving pedal efficiency and bike handling.

8. **Reliability and Durability** Manitou is known for building robust forks that hold up well over time, especially in demanding conditions. The air spring system is less prone to failure compared to older coil or external air spring designs.

9. **Good Value for Performance** Compared to some premium forks, the Dorado Air IRT offers excellent performance without the highest price tag, making it a strong choice for budget-conscious riders who still want high-end components.

10. **Compatibility with Modern Bikes** The Boost compatibility and 180mm travel make this fork a versatile choice for a wide range of bikes, from XC to light trail setups.

#### **Cons**

1. **Limited Travel for Aggressive Riding** At 180mm, this fork is not ideal for downhill (DH) or aggressive trail riding, where 200mm or more is often preferred. Riders pushing hard on technical descents may find it lacking in compression and rebound.

2. **Air Spring Limitations** While the internal air spring is convenient, it requires occasional maintenance (checking for leaks, adjusting sag, etc.). Some riders prefer the simplicity of a coil spring or external air spring for long-term reliability.

3. **Not as Light as Carbon Forks** If weight is a critical factor (e.g., for competitive XC), the aluminum construction means this fork will be heavier than carbon alternatives like the RockShox SID or Fox 36.

4. **Adjustment Complexity** The air spring system requires some familiarity with fork setup. Riders who are not comfortable adjusting sag or pressure may need to rely on a shop for maintenance.

5. **Price Relative to Alternatives** While still reasonable, the Dorado Air IRT is more expensive than basic entry-level forks (e.g., Fox 32 or RockShox Yari). For riders on a tight budget, there are cheaper options with similar travel.

6. **Limited Customization** Unlike some forks with adjustable rebound or compression damping, the Dorado Air IRT offers minimal tuning options. Riders who prefer fine-tuned damping may find it less flexible.

7. **Potential for Pumpiness** Some users report that the damping can feel slightly "pumpy" (excessive oscillation) under heavy loads or rough terrain, though this is subjective and may vary by rider weight and setup.

8. **Boost Hub Requirement** While Boost is now standard, some older bikes or budget builds may not use it, limiting compatibility for riders with non-Boost wheels.

### **Conclusion**

The **Manitou Dorado Air IRT 29 (180mm, Boost 20x110)** is an excellent choice for **cross-country and light trail riders** who prioritize **durability, adjustability, and smooth performance** without the complexity of a coil spring. Its **internal routing, air spring system, and Boost compatibility** make it a practical and high-performing fork for riders who want a balance of efficiency and comfort.

However, it is **not ideal for aggressive trail or downhill riding**, where longer travel and more adjustable damping would be beneficial. Riders who prefer **minimal maintenance** or **ultra-lightweight setups** may find alternatives like **RockShox SID, Fox 36, or coil-spring forks** more suitable.

If you ride mostly **fast, technical XC trails or light trail with moderate jumps**, the Dorado Air IRT is a **solid, reliable, and well-rounded choice**. For **heavier, more technical riding**, consider upgrading to a **200mm fork or one with more adjustable damping**.

### **Recommendation**

- **Buy it if:** You prioritize **durability, adjustability, and smoothness** for **XC or light trail riding**, and you want a **Boost-compatible fork** with **internal routing** to reduce maintenance.

- **Consider alternatives if:** You need **longer travel (200mm ) for aggressive trail or downhill**, prefer **minimal maintenance (coil spring)**, or want **ultra-lightweight performance (carbon fork)**.

- **Best for:** Riders who want a **versatile, high-quality fork** without the complexity of a coil setup, and who don t require extreme travel or damping adjustments.

For most **XC and light trail riders**, the **Manitou Dorado Air IRT is a great investment** that delivers **consistent performance and longevity**.
