Review SHIMANO Deore Xt Rd Rear Derailleur Sgs Long Cage Speed

The **Shimano DEORE XT RD-M772 Rear Derailleur (SGS Cage)** is a high-performance, precision-engineered component designed to deliver unmatched shifting efficiency and durability for cyclists demanding the best in mountain biking and gravel riding. Part of Shimano s DEORE XT lineup, this derailleur embodies the brand s commitment to innovation, combining cutting-edge technology with rugged reliability to handle the most demanding trails and technical terrain. The **SGS (Shimano Gold Series) cage** is a standout feature, offering an ultra-smooth and precise shifting experience by minimizing chain slap and reducing friction, which translates to faster, more consistent gear changes even under heavy loads. Engineered with a **durable aluminum frame**, the RD-M772 is built to withstand the rigors of aggressive riding, including sharp impacts and extreme angles, ensuring long-term performance without compromising on responsiveness.

At its core, the DEORE XT RD-M772 incorporates **Shimano s advanced shifting technology**, including the **Quick Release (QR) lever mechanism**, which allows for effortless installation and removal, making maintenance and adjustments quick and hassle-free. The **highly refined pulley system** ensures optimal chain alignment, reducing wear on both the derailleur and cassette while extending the lifespan of the drivetrain. The **adjustable B-tension screw** provides fine-tuned control over chain tension, accommodating different riding styles and terrain demands, whether you're tackling steep climbs or carving through technical descents. Additionally, the **durable spring mechanism** delivers consistent return-to-center performance, ensuring the derailleur remains reliable even after prolonged use in harsh conditions.

For cyclists who prioritize both performance and aesthetics, the DEORE XT RD-M772 features a **sleek, aggressive design** with a **black anodized finish**, blending seamlessly with Shimano s premium XT components while exuding a sporty, no-nonsense attitude. The **wide-range compatibility** of this derailleur makes it an excellent choice for setups with 1x, 2x, or even 3x drivetrains, offering versatility for riders who may upgrade or modify their systems in the future. Whether paired with a hardtail or a full-suspension bike, the RD-M772 excels in maintaining smooth operation under high loads, making it a favorite among enduro riders, trail specialists, and gravel enthusiasts who demand a derailleur that can keep up with their aggressive riding style.

Built to Shimano s exacting standards, the DEORE XT RD-M772 is a testament to the brand s engineering prowess, offering a perfect balance of **durability, precision, and performance**. Its **sealed bearings** and **high-quality materials** ensure minimal maintenance requirements, allowing riders to focus on the ride rather than upkeep. Whether navigating loose, rocky terrain or pushing through grueling climbs, this derailleur provides the confidence-inspiring reliability that serious cyclists expect from Shimano s XT lineup. For those seeking a derailleur that elevates their riding experience with every shift, the DEORE XT RD-M772 is a standout choice proving that great performance doesn t come at the expense of build quality or versatility.

The Shimano Deore XT RD-M772 rear derailleur (part number 689228130333) is a mid-range component designed for mountain biking and gravel 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 build quality, making it suitable for aggressive riding, rough terrain, and frequent use. The derailleur is designed to handle the stresses of mountain biking without frequent failures.

2. **Performance**: The M772 offers smooth shifting performance, which is crucial for trail riding where quick and precise gear changes are necessary. Shimano s clutch mechanism (if equipped) reduces chain slap and improves shifting consistency, especially in rough conditions.

3. **Compatibility**: This derailleur is compatible with a wide range of Shimano groupsets, including Deore, SLX, and older XT models, as well as some SRAM and other brands with minor adjustments. It works well with 1x, 2x, or 3x drivetrains, though it is most commonly paired with 1x setups in modern applications.

4. **Maintenance**: While no derailleur is completely maintenance-free, the Deore XT is relatively easy to maintain. Shimano s components are widely available, and replacement parts (such as pulleys, springs, and cables) are affordable and accessible.

5. **Value for Money**: Compared to higher-end Shimano groupsets like XTR or SLX, the Deore XT offers a good balance between performance and cost. It is often a popular choice for riders who want reliable performance without the premium price tag.

6. **Wide Range of Applications**: Beyond mountain biking, this derailleur can be used on gravel bikes, cross-country bikes, and even some endurance road bikes, depending on the setup. Its versatility makes it a practical choice for riders with varied riding styles.

7. **Shimano s Ecosystem**: If you are already invested in Shimano components, the M772 integrates seamlessly with other parts in the Shimano system, such as cassettes, cranks, and shifters. This can simplify upgrades and maintenance in the future.

---

**Cons:**

1. **Weight**: While not excessively heavy, the Deore XT is heavier than some higher-end derailleurs like Shimano XTR or SRAM s NX or XX1 models. For riders prioritizing weight savings, this could be a minor drawback, though the difference is often negligible in practical terms.

2. **Shift Quality Compared to Higher End**: While the M772 provides solid shifting performance, it may not match the precision and consistency of higher-end derailleurs like XTR or SLX. Some riders may notice slightly more chain slap or less smooth shifting under extreme conditions.

3. **Limited Upgrade Path**: If you plan to upgrade your drivetrain in the future, you may need to replace the derailleur as well, depending on the new groupset. For example, moving to a 12-speed setup or a higher-end groupset might require a different derailleur model.

4. **Durability Under Extreme Conditions**: While the Deore XT is durable, it may not handle the most extreme conditions (such as heavy-duty enduro or downhill riding) as well as specialized downhill or enduro-specific derailleurs. In such cases, a more robust option like Shimano s SLX or XTR might be preferable.

5. **Compatibility with Non-Shimano Systems**: While the M772 is versatile, pairing it with non-Shimano components (e.g., SRAM shifters or cranks) may require additional adjustments or adapters, which can complicate setup and maintenance.

6. **Aging Technology**: Shimano has since introduced newer models with improved features (e.g., wider chainstay clearance, better clutch mechanisms, or electronic shifting compatibility). The M772 lacks some of these advancements, which might be desirable for riders looking to future-proof their setup.

---

**Conclusion:**

The Shimano Deore XT RD-M772 rear derailleur is an excellent choice for riders seeking a reliable, mid-range derailleur that balances performance, durability, and affordability. It excels in mountain biking and gravel applications where robustness and smooth shifting are prioritized. While it may not offer the same level of precision or weight savings as higher-end options, its strengths far outweigh its minor drawbacks for most casual to intermediate riders. The derailleur is particularly well-suited for those who value Shimano s ecosystem, ease of maintenance, and a proven track record of performance in demanding conditions.

---

**Recommendation:**

If you are building or upgrading a mountain bike, gravel bike, or cross-country bike and are looking for a derailleur that offers a strong performance-to-cost ratio, the Shimano Deore XT RD-M772 is a solid and practical choice. It is ideal for riders who:

- Prioritize durability and reliability over weight savings.

- Ride primarily on trails, gravel, or cross-country routes.

- Want a derailleur that integrates well with other Shimano components.

- Are on a budget but still want high-quality performance.

However, if you are a competitive enduro or downhill rider, or if you plan to upgrade to a higher-end groupset in the near future, consider investing in a slightly more advanced derailleur like the Shimano SLX or XTR. For weight-conscious riders or those on a tight budget, the SRAM NX or XX1 derailleurs are also worth considering as alternatives. Ultimately, the M772 is a dependable workhorse that delivers consistent performance for the majority of riders.

I mounted this on a bike was building but removed it and went in another direction. There are some chain marks on the inside of cage from tuning but it wasn't ridden.
