Review AVID Rem Bb7 Mtn Mountain 180mm Front And Rear Rotor Black Breakset

The **Avid BB7 Mountain 180 Front/Rear Rotor Brakeset (Model 39-27-183)** is a high-performance, dual-piston hydraulic disc brake system meticulously engineered for serious mountain bikers who demand reliability, precision, and superior stopping power in the most demanding off-road conditions. Designed with Avid s signature innovation, this brakeset combines the proven efficiency of the BB7 caliper with the robust durability of the 180mm rotors, delivering an unmatched balance of control and modulation across a wide range of terrain from technical descents and aggressive climbs to high-speed descents and technical singletrack. The front and rear rotors, crafted from high-grade aluminum alloy, feature a **180mm diameter** with a **2mm thickness**, providing an optimal surface area for heat dissipation while maintaining a lightweight profile to minimize pedal weight and enhance overall bike responsiveness. The **dual-piston BB7 calipers** utilize Avid s **Hydraulic Disc Brake (HDB) technology**, ensuring consistent, progressive braking force with minimal fade, even under extreme conditions. The calipers are equipped with **Avid s exclusive hydraulic piston design**, which reduces piston drag and improves efficiency, allowing riders to modulate braking with greater finesse while maintaining strong, predictable stopping power. The **180mm rotors** are paired with **Avid s Centric Drilled rotors**, featuring a precision-drilled pattern that enhances heat dissipation and reduces weight without compromising structural integrity, making them ideal for riders who push their bikes to the limit. This brakeset is compatible with Avid s **MT400 hydraulic brake fluid**, which offers superior resistance to moisture absorption and temperature fluctuations, ensuring consistent performance across varying environmental conditions. The **BB7 calipers** also feature Avid s **Quick Release (QR) mounting system**, allowing for effortless installation and removal, while the **adjustable pad tensioning system** ensures optimal pad alignment and wear, extending the lifespan of both the pads and rotors. Whether tackling steep, root-laden descents or carving through technical trails, the Avid BB7 Mountain 180 brakeset provides the confidence-inspiring stopping power and reliability that serious mountain bikers rely on, making it a standout choice for riders who refuse to compromise on performance.

### **Pros and Cons of buying a Avid BB7 Mountain 180 Front & Rear Rotor Brake Set (Model: 39-27-183 REM)**

#### **Pros:**

1. **High Performance for Mountain Biking** The BB7 is a hydraulic disc brake designed specifically for aggressive mountain biking, offering strong stopping power even in wet or muddy conditions. The 180mm front rotor provides excellent modulation and control, which is crucial for downhill and technical trail riding.

2. **Durability and Reliability** Avid is a well-established brand known for durable brake components. The BB7 series is built to withstand heavy use, with reinforced components that resist wear from debris and high temperatures. The dual-piston calipers are robust and less prone to failure compared to cheaper alternatives.

3. **Consistent Braking in All Conditions** Hydraulic brakes eliminate cable sag and provide a more consistent feel than mechanical brakes. The BB7 s hydraulic system ensures progressive braking, reducing the risk of sudden lockups, which is important for safety on technical descents.

4. **Compatibility with Modern Mountain Bikes** This brake set is designed to work seamlessly with most 2016 mountain bikes that use 160mm or 180mm rotors (though 180mm is ideal for heavier riders or aggressive riding styles). It fits standard post-mount and direct-mount rotors, offering flexibility in upgrades.

5. **Good Modulation and Control** The BB7 s hydraulic system allows for fine-tuned braking, which is beneficial for riders who need precise control during cornering or rapid descents. The dual-piston design also provides better heat dissipation than single-piston setups.

6. **Widely Available and Supported** Avid is a trusted brand with extensive aftermarket support. Parts, replacements, and service are readily available, making maintenance and repairs easier compared to lesser-known brands.

7. **Suitable for Heavy Riders** The 180mm front rotor is ideal for riders weighing over 200 lbs (90 kg), as it provides the stopping power needed without excessive heat buildup.

---

#### **Cons:**

1. **Higher Upfront Cost** Compared to mechanical disc brakes or entry-level hydraulic systems, the BB7 is more expensive. While it justifies the price with performance, budget-conscious riders may opt for alternatives like Shimano Deore or SRAM Level T.

2. **Maintenance Requirements** Hydraulic brakes require occasional bleeding to remove air from the system, which can be a hassle if the rider lacks mechanical skills. Neglecting maintenance can lead to spongy or erratic braking.

3. **Weight** Hydraulic brakes are heavier than mechanical ones, which can slightly affect the bike s handling, especially on climbs. However, the difference is minimal compared to the performance benefits.

4. **Potential for Overheating** While the BB7 handles heat well, aggressive riders who rely heavily on the brakes (e.g., downhill or enduro) may experience reduced performance if the rotors overheat. Proper brake pads and cooling (e.g., rotor size, pad material) help mitigate this.

5. **Limited Upgrade Path** If a rider later wants to switch to a more advanced hydraulic system (e.g., Avid Code or SRAM Guide), they may need to replace the entire brake setup rather than just upgrading components.

6. **Pad Wear and Replacement Costs** High-performance brake pads wear out faster than those in less demanding setups. Replacing pads (especially high-end organic or semi-metallic types) can add to long-term costs.

7. **Learning Curve for Hydraulic Systems** First-time hydraulic brake users may struggle with bleeding the system or adjusting pressure, though this is a one-time learning process.

### **Conclusion:**

The Avid BB7 Mountain 180 front & rear rotor brake set is an excellent choice for serious mountain bikers who prioritize performance, reliability, and stopping power. It excels in demanding conditions, offers consistent braking, and is built to last under heavy use. However, it comes at a higher cost and requires more maintenance than mechanical brakes. If budget is a concern, alternatives like the Shimano Saint or SRAM Guide may offer a similar experience at a lower price, but the BB7 remains a top-tier option for riders who want Avid s proven quality.

### **Recommendation:** **Buy the Avid BB7 if:**

- You ride aggressively on technical or downhill trails.

- You prioritize strong, consistent braking in all weather conditions.

- You re willing to invest in a high-performance, durable brake system.

- You have experience with hydraulic brakes or are prepared to learn maintenance basics.

**Consider alternatives if:**

- You re on a tight budget and can compromise slightly on performance (e.g., Shimano Deore or SRAM Level T).

- You primarily ride cross-country or light trail and don t need the BB7 s extreme capabilities.

- You prefer a simpler, lower-maintenance system (though you d sacrifice braking power).

For most hard-core mountain bikers, the BB7 is a worthwhile upgrade that enhances safety and control, making it a strong recommendation for those who demand the best.

Pulled these off a fat bike I just bought they seem to work OK could use refresh pads/cables but as is full set of brakes includes calipers, levers and rotors the need be cleaned up.
