Review INDUSTRY NINE A35 Mountain Bike Stem 35mm Aluminum /-6 Orange 50mm

The **SA350040 A35 Mountain Bike Stem** is a premium, high-performance component designed to elevate the handling and responsiveness of your mountain bike, making it an ideal choice for riders seeking both durability and precision. Crafted from high-grade aluminum alloy, this stem features a **35mm drop-down design**, offering a sleek, aggressive riding position that enhances control and stability on technical trails, descents, and rough terrain. The **50mm clamp width** ensures a secure and snug fit on most 27.2mm (1.07-inch) fork steerer tubes, accommodating a wide range of fork models without compromising rigidity or alignment. With a **6-degree drop angle**, this stem optimizes weight distribution, allowing for better weight transfer and improved cornering grip, which is crucial for aggressive riders tackling steep climbs, sharp turns, and fast descents.

The **A35 model** stands out with its **threaded bottom bracket compatibility**, making it a versatile option for riders who prefer a more traditional, bolt-together setup rather than a through-axle system. This design choice not only enhances the stem s adjustability but also provides a robust connection to the frame, reducing the risk of wobble or misalignment under heavy loads. The stem s **anodized finish** not only adds a sleek, professional aesthetic but also provides excellent corrosion resistance, ensuring longevity even in harsh, off-road conditions where exposure to mud, water, and debris is common. The **integrated clamp system** is designed for easy installation and removal, allowing for quick adjustments or swaps without the need for specialized tools, which is particularly useful for riders who frequently modify their bike setup.

Beyond its technical specifications, the **SA350040 A35 Stem** is engineered with rider comfort and performance in mind. Its **low-profile design** reduces wind resistance, making it an excellent choice for high-speed riding on singletrack or downhill runs where aerodynamics play a subtle but meaningful role. The stem s **precise machining** ensures a tight seal with the fork steerer, minimizing play and maximizing stiffness, which translates to better feedback and control during aggressive maneuvers. Whether you're a competitive enduro rider pushing the limits of your bike or a trail enthusiast exploring rugged landscapes, this stem delivers the strength, adjustability, and responsiveness needed to tackle any challenge. Its compatibility with a broad range of mountain bike frames and forks makes it a standout choice for riders looking to upgrade their setup without sacrificing versatility or performance.

The **SA350040 (A35) Mountain Bike Stem** from **35mm to -6 with a 50mm rise** is a popular choice for many riders, but it has distinct advantages and drawbacks depending on your riding style, bike setup, and preferences. Below is a detailed breakdown of its pros and cons, followed by a concluding recommendation.

---

### **Pros of the SA350040 (A35) Stem**

1. **Adjustable Steering Axis Inclination (SAI)**

The A35 stem allows you to adjust the **steering axis inclination (SAI)** between **-6 and 6 **, which is one of its most significant features. This adjustability is particularly useful for:

- **Fine-tuning handling** You can dial in the perfect steering feel for your riding style, whether you prefer a more upright or aggressive geometry.

- **Compensating for frame geometry** If your bike s stock stem angle is too steep or shallow, the A35 lets you correct it without buying a new stem.

- **Adapting to different riding conditions** Some riders prefer a slightly steeper angle for better control on rough terrain, while others like a more upright feel for comfort.

2. **50mm Rise**

- **Comfort on long rides** Reduces neck and back strain by keeping the rider more vertical.

- **Better control on technical trails** A higher rise can improve stability when navigating tight turns or rough descents.

- **Compatibility with dropper posts** The upright position works well with dropper posts, allowing for a more natural reach when descending.

3. **Durability and Build Quality**

The A35 stem is made from **aluminum**, which is strong yet lightweight, making it suitable for aggressive riding. It features a **threaded clamp system** (not a bolt-through design), which is generally more durable and less prone to stripping over time.

4. **Wide Compatibility**

The **35mm clamp width** is standard for many modern mountain bikes, making it easy to install on most bikes without needing spacers or adapters.

5. **Adjustable Clamp Tightening**

The **dual-bolt clamp system** allows for even tightening, reducing the risk of clamp slippage or uneven pressure on the handlebars.

6. **Good for Endurance and All-Mountain Riding**

If you ride a mix of **endurance and aggressive trails**, the adjustable SAI and upright position make this stem versatile for different conditions.

---

### **Cons of the SA350040 (A35) Stem**

1. **Limited SAI Range (-6 to 6 )**

While the ** 6 range is useful**, some riders particularly those on **extremely aggressive downhill bikes** or **hardtail bikes with steep head tubes** may need a **wider adjustment range** (e.g., -12 to 12 ). If your bike s stock stem angle is far outside this range, the A35 may not be sufficient.

2. **Not Ideal for Extreme Downhill or Freeride**

If you ride **steep, aggressive downhill trails or freeride**, a **steeper stem angle (e.g., -12 or more)** is often preferred for better control and responsiveness. The A35 s maximum steepness of **-6 ** may feel too upright for such riding styles.

3. **Weight**

While the A35 is not overly heavy, it is **not as light as some carbon stems** (if you re running carbon handlebars). However, for most riders, the weight difference is negligible compared to the benefits of adjustability.

4. **Installation Complexity**

- **Measure and adjust the SAI** before final tightening.

- **Ensure proper torque specifications** to avoid stripping the bolts.

- **Check for proper alignment** to prevent binding or uneven wear.

5. **Potential for Misalignment**

If not installed correctly, an adjustable stem can lead to **uneven clamp pressure, binding, or premature wear** on the headset. This requires careful attention during setup.

6. **Cost Compared to Fixed Stems**

The A35 is **more expensive than a basic fixed stem** (e.g., a simple 35mm stem with no adjustment). If you don t need adjustability, a cheaper fixed stem may suffice.

7. **Not Suitable for All Frame Types**

- **Hardtail bikes with very steep head tubes** may still need a **steeper stem** than what the A35 offers.

- **Full-suspension bikes with aggressive geometry** might benefit from a **more aggressive SAI** than -6 .

---

### **Conclusion and Recommendation**

- Want **adjustable steering geometry** to fine-tune their bike s handling.

- Prefer an **upright riding position** for comfort on endurance or mixed-terrain riding.

- Need a **versatile stem** that works well with dropper posts.

- Ride **trails that require a balance between control and comfort** (e.g., all-mountain, trail, or light enduro).

- Riders who need **extreme steepness** (e.g., downhill or freeride).

- Those who prioritize **minimal weight** over adjustability (though the weight difference is small).

- Beginners who may not want the **extra setup complexity**.

You want **adjustable steering axis inclination** to dial in your ideal geometry.

You ride a mix of **endurance and aggressive trails** and need a **upright yet responsive** setup.

Your bike s stock stem angle is **within the -6 to 6 range**, or you want to fine-tune it.

You value **comfort and versatility** over extreme downhill performance.

You need **steeper angles (-12 or more)** for downhill/freeride.

You prefer **simplicity and lower cost** of a fixed stem.

You re unsure about **installation and adjustment** and may not use the full range.

For most **all-mountain, trail, and enduro riders**, the A35 is a **top-tier choice** that offers the best of both worlds adjustability and a comfortable ride. If you re on the fence, **test-ride a bike with this stem** to see if the adjustability suits your riding style.

Used for a few rides on my yellow colored bicycle before going to black. Lightly used I9 orange stem for 35mm bar, in 50mm length . No noticeable wear or damage, never crashed.
