Review FOX 36 27.5in Lowers Mountain Bike

The **Fox Float 36 27.5" Lower Fork** (model 820-09-063) is a cutting-edge, high-performance suspension component designed specifically for modern mountain bikes, delivering an unparalleled blend of compliance, responsiveness, and durability. Engineered by Fox, one of the most respected names in off-road suspension technology, this fork is tailored for aggressive riders tackling everything from technical trail sections and rocky descents to fast, flowing singletrack and aggressive enduro laps. The **Float 36** platform features a **36mm stanchion design**, which optimizes energy transfer and damping efficiency while maintaining a compact, bike-friendly profile. This allows for a more direct, connected feel on rough terrain, reducing wasted motion and enhancing rider control without sacrificing the plush, absorbing characteristics that define Fox s legendary suspension.

At the heart of the Float 36 is **Fox s proprietary Float Technology**, a system that combines **adjustable rebound and compression damping** with a **pneumatic air spring** for precise tuning. The **rearward-mounted air chamber** ensures consistent performance across varying loads, while the **adjustable rebound damping** allows riders to fine-tune the fork s responsiveness whether they prefer a snappy, aggressive setup for fast descents or a smoother, more forgiving feel for technical climbs. The **compression damping** is equally refined, offering **low-speed and high-speed adjustments** to dial in the perfect balance between control and comfort, making this fork ideal for riders who demand adaptability across diverse terrains.

Constructed with **high-grade aluminum and steel components**, the Float 36 is built to withstand the rigors of extreme riding. The **steel crown** provides durability and strength, while the **aluminum stanchions** keep the fork lightweight without compromising stiffness. The **sealed cartridge-based damping system** ensures long-lasting performance, minimizing maintenance requirements while delivering consistent, reliable function even under heavy use. Additionally, the **Fox Float 36** is compatible with **27.5-inch wheels**, making it a versatile choice for riders on bikes ranging from cross-country to downhill-focused builds, though it excels particularly well in **trail and enduro applications** where a balance of speed and control is essential.

For added convenience and customization, the Float 36 features **Fox s proprietary Float Tool**, a simple yet effective system that allows riders to adjust the sag and damping settings on the go. This tool enables quick tuning without the need for specialized tools, making it easier than ever to optimize the fork s performance for different conditions or rider preferences. The **air spring** also supports **Fox s proprietary air pressure system**, which can be adjusted to match rider weight and desired stiffness, further enhancing the fork s adaptability.

Whether you're carving through technical descents, bombing down steep switchbacks, or navigating root-laden climbs, the **Fox Float 36 27.5" Lower Fork** delivers a harmonious blend of power, precision, and comfort. Its **sleek, aggressive aesthetic** complements modern mountain bike designs, while its **engineered performance** ensures it stands as a benchmark for suspension excellence. Built for riders who refuse to compromise, this fork is not just an upgrade it s a game-changer, pushing the boundaries of what s possible on two wheels.

The Fox 820-09-063 36 27.5-inch lowers for a mountain bike is a popular choice among riders seeking a balance of performance, durability, and adjustability. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Fox 820-09-063 36 27.5-inch Lowers**

1. **High-Quality Build and Durability**

The Fox 820 is a premium suspension fork designed for demanding conditions. It features a robust construction with a steel crown, aluminum steerer tube, and high-grade aluminum alloy tubes, ensuring long-lasting performance even under heavy use. The sealed cartridge system reduces maintenance needs compared to older fork designs.

2. **Adjustable Air Spring (Air Sac)**

The inclusion of an air sac allows for precise air pressure adjustments, enabling riders to fine-tune the fork s sag and responsiveness. This is particularly useful for riders of varying weights or those who frequently switch between different riding styles (e.g., cross-country and trail riding). The air sac also helps protect the air spring from damage in case of a crash.

3. **Wide Range of Travel (100mm)**

With 100mm of travel, this fork is well-suited for trail and all-mountain riding, offering enough compression to handle rough terrain while maintaining efficiency for climbing. The travel is generous enough for most riders but may feel limiting for aggressive downhill or freeride riding, where 120mm or more is often preferred.

4. **Reliable Damping System**

Fox is known for its damping technology, and the 820 fork includes a high-quality damper that provides smooth, consistent performance. The damping is tuned to handle a wide range of speeds and terrain, reducing bottoming out and improving ride quality. The fork s rebound and compression damping can be adjusted via the remote or on-the-fly, giving riders control over their ride feel.

5. **Compatibility and Fit**

The 27.5-inch wheel size is versatile and widely used in modern mountain bikes, offering a balance between the agility of 26-inch wheels and the stability of 29-inch wheels. The fork is designed to fit standard 27.5-inch bikes, and the 36mm crown width ensures compatibility with most frames. Additionally, the fork s steerer tube is 1-1/8 inches, which is standard for most modern bikes.

6. **Low Maintenance**

As a sealed cartridge fork, the Fox 820 requires less frequent servicing compared to open-air forks. The sealed system reduces the risk of dirt and debris affecting the air spring or damper, though it s still important to perform regular checks and clean the fork as needed.

7. **Good for Versatile Riding**

The fork s tuning makes it suitable for a variety of disciplines, including cross-country, trail, and light all-mountain riding. Riders who frequently switch between different types of terrain will appreciate the fork s adaptability.

8. **Positive User Feedback**

Many riders praise the Fox 820 for its smooth ride, durability, and ease of use. It s a popular choice among both amateur and experienced riders, and its reputation for reliability adds to its appeal.

### **Cons of the Fox 820-09-063 36 27.5-inch Lowers**

1. **Limited Travel for Aggressive Riding**

While 100mm of travel is adequate for trail and all-mountain riding, it may feel insufficient for riders who frequently tackle steep descents, jumps, or technical downhill sections. In such cases, a fork with 120mm or more travel (e.g., Fox 34 or 36) would be more appropriate.

2. **Weight**

The Fox 820 is not the lightest fork on the market. At around 2.5 2.7 kg (depending on the exact model and build), it adds noticeable weight to the front end of the bike. Lighter forks (e.g., RockShox Lyrik or Suntour XCR) may be preferable for cross-country riders who prioritize weight savings.

3. **Cost**

The Fox 820 is a premium fork, and its price reflects that. While it offers excellent value for its quality and performance, it may be out of budget for riders on a tight budget. There are more affordable alternatives (e.g., RockShox Recon, Suntour XCR) that still provide good performance for trail riding.

4. **Air Sac Limitations**

While the air sac is a useful feature, it can be finicky to adjust, especially for beginners. Over-inflating the air spring can lead to a harsh ride, and under-inflating can result in excessive sag or poor performance. Riders who prefer a simpler setup (e.g., coil forks) might find the air sac system less intuitive.

5. **Service Requirements**

Although the Fox 820 is a sealed cartridge fork, it still requires periodic maintenance. Over time, the air spring and damper may degrade, and the fork may need servicing every 1,000 2,000 miles or so, depending on usage. This can add to the long-term cost of ownership.

6. **Not Ideal for Freeride or DH**

For riders who specialize in freeride, enduro, or downhill, the 100mm travel may not be enough to handle the extreme demands of those disciplines. A longer-travel fork (e.g., Fox 34 or 36) or even a dual-crown fork would be a better fit.

7. **Potential for Bottoming Out**

While the damping is generally good, riders who frequently hit rough terrain at high speeds may still experience bottoming out, especially if the air pressure is not optimized for their weight and riding style. This can lead to a harsh impact and potential damage to the fork or bike.

---

### **Conclusion**

The Fox 820-09-063 36 27.5-inch lowers is an excellent choice for riders seeking a reliable, high-performance fork for trail and all-mountain riding. Its adjustable air spring, robust build, and smooth damping make it a versatile option for a wide range of riders. However, it is not without limitations its weight, cost, and limited travel may not suit every rider, particularly those who prioritize weight savings or engage in aggressive downhill riding.

For most trail riders, cross-country enthusiasts looking for a bit more comfort, and all-mountain riders who don t need extreme travel, the Fox 820 is a fantastic investment. It strikes a balance between performance, durability, and adjustability, making it a popular and well-regarded fork in the mountain biking community.

- You ride primarily on trails, all-mountain terrain, or light enduro courses.

- You frequently ride aggressive downhill or freeride terrain and need more travel (e.g., Fox 34 or 36).

- You are on a tight budget and can find a similarly performing fork at a lower price (e.g., RockShox Recon, Marzocchi Sette).

- You prefer a simpler setup and are not interested in adjusting air pressure (e.g., coil forks like the RockShox Deluxe).

In summary, the Fox 820 is a top-tier fork for its intended use, and for most riders, it will be a great choice. However, carefully consider your riding style, budget, and priorities before making a final decision.
