The **Shimano FH-580 DEORE LX Rear Hub Release Skewer (36H)** is a precision-engineered component designed to deliver both reliability and performance for mountain biking enthusiasts and casual riders alike. This skewer is a key part of Shimano s DEORE LX drivetrain lineup, offering a seamless integration with the brand s high-quality components while ensuring smooth, secure wheel removal and installation. Crafted from durable, high-grade steel, the FH-580 skewer is built to withstand the rigors of off-road riding, including rough terrain, heavy braking forces, and frequent adjustments. Its **36H (36mm) diameter** provides a robust fit for modern mountain bike wheels, ensuring stability and minimizing lateral play, which is critical for maintaining optimal handling and braking efficiency. The skewer features Shimano s proprietary **Quick Release (QR) mechanism**, allowing for quick and effortless wheel removal without the need for specialized tools, making maintenance and repairs faster and more convenient. The design incorporates a **threaded end** on one side for secure attachment to the rear axle, while the other end includes a **spring-loaded pin** that locks into place when tightened, ensuring the wheel stays firmly in position during rides. This dual-functionality enhances both convenience and safety, reducing the risk of wheel slippage or detachment under high-stress conditions. The FH-580 skewer is compatible with Shimano s DEORE LX rear hubs, offering a cohesive system that optimizes performance and durability. Whether navigating technical trails, tackling steep descents, or simply enjoying a leisurely ride, this skewer provides the confidence of a secure, well-supported wheel setup. Its robust construction and thoughtful engineering make it an excellent choice for riders seeking a balance of performance, ease of use, and long-term reliability.
The **Shimano FH-F580 Deore LX Rear Hub Release Skewer (36H)** is a budget-friendly option for mountain biking, but it has distinct advantages and limitations depending on your needs. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
---
### **Pros**
1. **Budget-Friendly**
The FH-F580 is one of Shimano s most affordable rear skewers, making it a practical choice for riders on a tight budget or those looking to upgrade a used bike without overspending. It s significantly cheaper than higher-end models like the FH-FC500 or FH-FC600.
2. **Decent Durability for the Price**
While not built for extreme durability, the FH-F580 is made from steel, which is more robust than aluminum in some cases (though not as strong as high-end carbon or titanium skewers). It should hold up well for casual to moderate riding, especially on well-maintained bikes.
3. **Compatibility with Shimano Deore LX Components**
As part of Shimano s Deore LX line, this skewer is designed to work seamlessly with other Deore LX components (e.g., derailleurs, shifters, and hubs). This makes it a straightforward upgrade or replacement for bikes in the same group.
4. **Easy to Install and Remove**
The design is straightforward, with a simple release mechanism that doesn t require specialized tools. This makes it accessible for riders who prefer to handle basic maintenance themselves.
5. **Wide Availability**
Due to its popularity and Shimano s extensive distribution network, the FH-F580 is easy to find in bike shops, online marketplaces, and even as spare parts for used bikes.
6. **Basic Functionality**
For riders who don t need high-end features (like quick-release compatibility or carbon construction), the FH-F580 provides the essential function of securing the rear wheel without complications.
---
### **Cons**
1. **Limited Durability for Aggressive Riding**
The FH-F580 is not designed for heavy-duty use, such as downhill racing, extreme jumps, or frequent high-speed impacts. The steel construction can bend or wear out over time, especially if the bike is ridden aggressively or on rough terrain regularly.
2. **No Quick-Release (QR) Compatibility**
Unlike some higher-end skewers (e.g., Shimano s FC series), the FH-F580 does not include a quick-release mechanism. This means you ll need to use a traditional skewer tool or a hex key to remove it, which can be less convenient than a QR system.
3. **Basic Release Mechanism**
The release mechanism is functional but not as refined as higher-end options. It may require more force to engage or disengage, and the spring can weaken over time, making the release less reliable.
4. **No Carbon or Lightweight Materials**
The FH-F580 is made of steel, which adds weight compared to carbon or aluminum skewers. While the difference is minimal, it s something to consider if weight savings are a priority.
5. **Potential for Rust or Corrosion**
Steel skewers are more prone to rust, especially if the bike is stored in damp conditions or not cleaned regularly. This can lead to stiffness or failure over time if not maintained properly.
6. **Limited Longevity Compared to Higher-End Models**
While it s not a disposable part, the FH-F580 may need replacement sooner than premium skewers (e.g., Shimano FC500 or SRAM s carbon options) if subjected to heavy use or poor maintenance.

### **Conclusion**
The **Shimano FH-F580 Deore LX Rear Hub Release Skewer (36H)** is a solid, no-frills option for riders who prioritize affordability and basic functionality. It s ideal for:
- Casual or recreational riders.
- Budget-conscious buyers upgrading a used bike.
- Riders who don t need quick-release convenience or ultra-lightweight materials.
- Those who prefer simplicity and don t plan to abuse the bike with extreme riding.
However, if you ride aggressively, prioritize weight savings, or want a more durable and convenient release mechanism, investing in a higher-end skewer (e.g., Shimano FC500, SRAM s carbon skewers, or a QR-compatible option) would be a better long-term choice. The FH-F580 is a practical compromise for those who don t need the extra features but want a reliable, low-cost solution.

### **Recommendation**
**Buy the FH-F580 if:**- You re on a tight budget and need a basic, functional skewer.
- Your riding style is casual or moderate (e.g., trail riding, commuting).
- You re upgrading a used bike with Deore LX components.
- You don t mind using a skewer tool for removal and don t need quick-release convenience.
**Avoid the FH-F580 if:**- You ride aggressively (e.g., downhill, enduro, or jump-heavy terrain).
- You prioritize weight savings or want a lighter skewer.
- You frequently ride in wet conditions without proper maintenance.
- You want a skewer with a quick-release mechanism for faster wheel changes.
**Alternative Considerations:**- For **better durability and release mechanism**, consider the **Shimano FH-FC500** (still budget-friendly but more refined).
- For **quick-release convenience**, look at **SRAM s carbon skewers** or **Shimano s FC series** (though these are pricier).
- For **used bikes or extreme riding**, a **high-quality steel skewer** (e.g., from Race Face or DT Swiss) might offer a better balance of cost and performance.
