Review ORBEA Components Mountain Bike Riser Bar Aluminum 800mm 35mm Black

The **Orbea HBM-C21 Mountain Bike Riser Bar** is a meticulously engineered component designed to elevate both performance and comfort for aggressive trail riding, downhill, and extreme enduro disciplines. Crafted from Orbea s signature **HBM (High Performance Material)** a lightweight yet ultra-durable alloy this riser bar delivers an optimal blend of stiffness, responsiveness, and rider control. With an **800mm width**, it provides ample shoulder clearance for riders of varying builds, ensuring a natural, ergonomic grip position that minimizes strain during long descents or technical climbs. The **35mm rise** enhances pedal clearance, allowing for aggressive pedal strikes and smoother transitions between pedaling and standing positions, which is particularly beneficial for riders who favor a more dynamic, free-wheeling style. The bar s **smooth, contoured shape** and **ergonomic design** reduce hand fatigue, while the **integrated cable routing channels** keep brake and shift cables neatly organized, preventing tangling and improving overall system efficiency. Built to withstand the rigors of high-speed descents and rough terrain, the HBM-C21 features **reinforced dropouts** and **precision-machined mounting points** for seamless compatibility with Orbea s full suspension forks and stem systems. Whether tackling steep technical climbs or carving through double-black diamond trails, this riser bar ensures a confident, connected interface between rider and bike, making it an essential upgrade for those seeking both performance and precision in their mountain biking experience.

### **Pros and Cons of buying a Orbea HBM-C21 Mountain Bike Riser Bar (800mm, 35mm)**

#### **Pros**

1. **Ergonomic Design** The riser bar is engineered to improve comfort and reduce wrist strain by elevating the hands, which is particularly beneficial for long rides or technical trails. The slight rise helps maintain a more natural hand position, reducing pressure on the wrists and forearms.

2. **Wide Reach (800mm)** The 800mm width provides ample space for riders with broader shoulders or those who prefer a more stable, less cramped grip. This can be especially useful for riders who feel constrained by narrower bars.

3. **Durable Construction** Orbea is known for high-quality materials, and the HBM-C21 features a robust aluminum build with a sleek, aerodynamic shape. The 35mm thickness offers a good balance of stiffness and comfort, reducing flex that could lead to fatigue.

4. **Compatibility** The bar is designed to fit most mountain bike frames with standard dropper post or flat bar mounts. It works well with Orbea s own dropper posts (like the HBM-C21 s intended pairing) and can be adapted to other brands with appropriate spacers or adapters.

5. **Aesthetic Appeal** The bar has a clean, modern look with subtle branding that appeals to riders who value both function and style. The matte finish resists fingerprints and scratches better than glossy coatings.

6. **Adjustability** While not a true riser/reach-adjustable bar, the fixed geometry still offers a neutral position that many riders find more comfortable than aggressive flat bars. Some riders may prefer the ability to fine-tune reach, but the HBM-C21 strikes a practical balance.

7. **Lightweight** The aluminum construction keeps the bar relatively light, which is beneficial for climbs and overall handling without adding unnecessary weight.

8. **Versatility** Suitable for both trail riding and light enduro use, though it may not be ideal for extreme downhill or freeride where more aggressive bar angles are preferred.

#### **Cons**

1. **Fixed Geometry** Unlike fully adjustable riser/reach bars (e.g., some dropper post-compatible riser bars), the HBM-C21 has a fixed rise and reach. Riders who need to adjust their hand position frequently (e.g., for different terrains or personal preference) may find this limiting.

2. **Price** As an Orbea product, the HBM-C21 is positioned in the mid-to-high price range for riser bars. While not excessively expensive, it may be seen as overkill for casual riders or those on a tight budget who could opt for a more basic flat bar or a simpler riser bar from a different brand.

3. **Dropper Post Dependency** The bar is optimized for use with Orbea s dropper posts (or compatible third-party options). If you don t already have a dropper post or plan to invest in one, this adds to the upfront cost. Without a dropper, the riser bar s benefits are somewhat diminished.

4. **Narrower Appeal for Some Riders** While the 800mm width is generous, riders with extremely wide shoulders or those who prefer even more reach (e.g., 820mm or wider) may find it slightly restrictive. Conversely, riders with narrower shoulders might find it overly wide.

5. **Minimal Rise for Some** The rise on the HBM-C21 is moderate (not as aggressive as some riser bars designed for extreme comfort). Riders who prioritize a higher rise to alleviate wrist pain or neck strain may prefer a bar with a more pronounced elevation.

6. **Brand Loyalty** Orbea s products are high-quality but may not offer the same level of customization or after-sales support as some other brands (e.g., Fox, Salsa, or Lefty). If you re looking for a bar with more options for tweaking reach or rise, you might explore alternatives.

7. **Potential Compatibility Issues** While the bar is designed to be versatile, fitting it to non-Orbea frames may require additional spacers or adapters, which could complicate installation or affect the final feel.

### **Conclusion**

The **Orbea HBM-C21 riser bar (800mm, 35mm)** is a well-engineered, comfortable, and durable option for riders who prioritize ergonomics, stability, and a neutral hand position. It excels for trail riding, enduro, and climbs where comfort and control are key. However, its fixed geometry and higher price point may not suit riders who need adjustability or those on a budget. It s particularly well-suited for riders who already use Orbea s dropper posts or are looking for a premium, no-frills riser bar that enhances comfort without sacrificing performance.

If you value Orbea s build quality, the bar s ergonomic benefits, and its compatibility with your existing setup, it s a solid choice. For riders who need more adjustability or a wider range of reach options, alternatives like the **Fox Rift, Salsa Fargo, or Lefty Riser Bars** might be worth considering.

### **Recommendation**

- You already have (or plan to get) an Orbea dropper post and want a high-quality, ergonomic riser bar.

- You prefer a neutral, comfortable hand position for trail or enduro riding.

- You have a frame that accommodates the 800mm width without feeling too cramped.

- You value Orbea s reputation for durability and design.

- You need adjustable rise/reach and are open to more customizable options.

- You re on a tighter budget and could find a comparable riser bar from another brand at a lower cost.

- You ride primarily in aggressive downhill or freeride terrain where more aggressive bar angles are preferred.

Overall, the HBM-C21 is a **strong choice for riders who want a reliable, comfortable riser bar without unnecessary complexity**.
