Review SHIMANO Deore Xt Linkglide Speed Rear Derailleur Long Cage Sgs

The **Shimano DEORE XT RD-M8130SGS LinkGlide Rear Derailleur Cage** represents the pinnacle of precision engineering and performance optimization within Shimano s mid-range drivetrain lineup, meticulously crafted for cyclists who demand reliability, efficiency, and a seamless shifting experience across demanding terrains. This rear derailleur is the heart of the DEORE XT system, designed to deliver razor-sharp, consistent shifting with minimal friction, even under the most grueling conditions. The **SGS (Shimano Gold Series)** designation underscores its premium build quality, featuring a robust **aluminum alloy cage** that balances weight savings with structural integrity, ensuring durability without compromising on performance. The **LinkGlide mechanism**, a hallmark of Shimano s innovation, eliminates the need for a derailleur hanger, streamlining the drivetrain setup and reducing potential points of failure, while also enhancing chain retention for added security during aggressive riding styles.

At its core, the **RD-M8130SGS** is engineered to accommodate Shimano s **11-speed** cassette systems, offering a **12.5-tooth minimum cage size** and a **44-tooth maximum pulley size**, which optimizes chainline alignment and shifting performance across a wide range of rear sprockets. The **micro-spline shift mechanism** ensures smooth, progressive indexing, minimizing chain slap and providing predictable, repeatable shifts critical for climbers and descending riders who rely on precise gear engagement. The **LinkGlide design** further enhances this by integrating a **built-in chain guide**, which reduces lateral chain movement and wear, extending both the derailleur s lifespan and the longevity of the cassette and chain.

For riders who demand versatility, the **RD-M8130SGS** is compatible with Shimano s **11-speed Deore XT** and **XT M8100** groupsets, making it an ideal upgrade for those looking to refine their drivetrain without a full system overhaul. Its **durable steel jockey wheels** and **high-performance bearings** are sealed against dust and moisture, ensuring consistent performance in all weather conditions, from wet mountain trails to dusty gravel roads. The **adjustable limit screws** allow for fine-tuning of high and low limits, accommodating custom cassette setups or rider-specific preferences, while the **quick-release body** simplifies installation and removal, a boon for maintenance and repairs on the go.

Beyond its technical specifications, the **DEORE XT RD-M8130SGS** embodies Shimano s commitment to **ergonomic efficiency and rider-centric design**. Its compact yet robust form factor minimizes interference with wheel clearance, making it suitable for both road and mountain bikes equipped with wider tires. The **corrosion-resistant finish** ensures longevity in harsh environments, while the **precise shift feel** provides immediate feedback, allowing riders to focus on their performance rather than their drivetrain. Whether tackling a technical descent, crushing a grueling climb, or cruising on a long-distance ride, this derailleur delivers the **reliability and responsiveness** that serious cyclists expect from Shimano s mid-tier offerings. For those seeking a derailleur that bridges the gap between affordability and high performance, the **RD-M8130SGS** stands as a testament to Shimano s ability to deliver **cutting-edge technology in a package that s as practical as it is powerful**.

The **Shimano Deore XT RD-M8130 LinkGlide Rear Derailleur (SGS)** is a mid-range derailleur designed for mountain biking and cross-country riding. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Reliability and Durability**

The Deore XT series is known for its robust construction, making it suitable for aggressive riding, rough terrain, and frequent use. The SGS (Single-Gear Select) mechanism improves shifting consistency, reducing the risk of derailments caused by chain misalignment.

2. **LinkGlide Technology**

Shimano s LinkGlide design reduces chain noise and wear by improving chain engagement with the derailleur pulleys. This results in smoother shifting and extended chain life, which is beneficial for riders who prioritize efficiency and longevity.

3. **Mid-Range Performance**

The M8130 offers better performance than entry-level derailleurs (e.g., SLX) while remaining more affordable than top-tier models (e.g., SLX or higher-end XT). It handles well in cross-country and light trail riding, providing precise shifting for most casual to intermediate riders.

4. **Compatibility**

The derailleur is compatible with Shimano s Deore XT drivetrain components, including chainrings, cassettes, and cranks. It also works well with other brands chains and cassettes, though Shimano s own parts are optimized for performance.

5. **Maintenance-Friendly**

Deore XT components are widely available and relatively easy to maintain. Spare parts, tools, and service knowledge are abundant, making repairs and adjustments straightforward for DIYers or mechanics.

6. **Weight Considerations**

While not as lightweight as ultra-lightweight derailleurs (e.g., SLX or carbon models), the M8130 strikes a balance between performance and weight, making it suitable for riders who don t need the absolute lightest setup but still want responsiveness.

7. **Shimano s Reputation**

Shimano is a trusted brand with decades of experience in bicycle components. The Deore XT line is well-tested and proven in various riding conditions, offering confidence in its performance and build quality.

---

### **Cons**

1. **Limited for Aggressive or Heavy Use**

While durable, the M8130 may struggle with extreme downhill riding, heavy loads, or repeated high-stress conditions (e.g., frequent jumps or aggressive cornering). For such use, a more robust derailleur (e.g., SLX or higher) or a carbon model would be preferable.

2. **No Electronic Shifting**

The M8130 is a mechanical derailleur, which means it lacks the precision and convenience of electronic shifting (e.g., Di2). Electronic systems offer smoother, faster, and more consistent shifts, which can be a drawback for riders who prioritize modern technology.

3. **Chain Wear and Noise**

While LinkGlide reduces noise and wear compared to older designs, it is not immune to chain wear over time. Riders who frequently ride in muddy or abrasive conditions may experience faster chain and derailleur wear, requiring more frequent maintenance.

4. **Price Point**

The M8130 is positioned as a mid-range derailleur, and while it offers good value, it may not justify the cost for riders who already have a high-end drivetrain. For those on a budget, entry-level derailleurs (e.g., Deore SLX) might suffice for lighter use.

5. **Limited Upgrade Path**

If a rider later decides to upgrade to a higher-end drivetrain (e.g., SLX or higher), they may need to replace the derailleur as well, as compatibility can vary. This could add to long-term costs if the initial setup is not future-proofed.

6. **Build Quality Variations**

While generally durable, some users report minor issues with derailleur hanger alignment or pulley wear over time, especially in harsh conditions. Regular checks and adjustments are recommended to maintain optimal performance.

---

### **Conclusion**

The **Shimano Deore XT RD-M8130 LinkGlide Rear Derailleur (SGS)** is an excellent choice for riders seeking a reliable, mid-range derailleur for cross-country, light trail, or casual mountain biking. Its LinkGlide technology enhances shifting smoothness and reduces noise, while its durability and compatibility make it a practical option for most riders. However, it may not be sufficient for aggressive downhill riding or riders who prioritize electronic shifting or ultra-lightweight components.

For riders who primarily use their bike for cross-country, fitness riding, or light trail use, the M8130 offers a strong balance of performance, value, and ease of maintenance. Those who push their bikes harder or seek the latest technology may find it limiting and could benefit from upgrading to a higher-end or electronic derailleur.

---

### **Recommendation**

- **Buy the Shimano Deore XT RD-M8130** if:

- You ride primarily on cross-country trails, gravel, or casual mountain biking.

- You want a durable, reliable derailleur with smooth shifting and minimal noise.

- You prefer mechanical shifting and are comfortable with occasional maintenance.

- You are building or upgrading a mid-range drivetrain and want a cost-effective solution.

- **Consider alternatives if:**

- You ride aggressively on technical or downhill terrain, in which case a **Shimano SLX or higher-end XT derailleur** (e.g., RD-M8100) or a **carbon derailleur** (e.g., SRAM NX or higher) may be better.

- You prefer electronic shifting, in which case a **Di2-compatible derailleur** (e.g., Shimano Deore Di2 or SRAM eTap) would be more suitable.

- You are on a tight budget and can tolerate slightly less precise shifting, in which case an **entry-level Deore SLX derailleur** might suffice.

Details:

It was installed but removed when I realized my cassette not compatible with the LinkGlide derailleur. This derailleur has never been ridden. The wear spot on the back of stamped cage was caused by derailleur rubbing against cassette when I attempting to set tension and Hi/Low stops.
