Review SHIMANO Ultegra 8/9/10 Speed Rear Hub 28-h 130mm
The **Shimano FH-F6600 Ultegra 130mm 28-hole Rear Hub** represents the pinnacle of precision engineering and performance within Shimano s high-end drivetrain ecosystem, designed exclusively for road cyclists seeking uncompromising efficiency, durability, and a seamless integration with the latest 10-, 9-, or 8-speed Ultegra groupsets. This hub is a masterclass in lightweight construction and aerodynamic optimization, crafted from a high-strength aluminum alloy that balances stiffness with weight savings, ensuring minimal rotational inertia to enhance pedal efficiency and responsiveness. The **130mm axle width** is a modern standard for contemporary road frames, offering ample clearance for disc brakes while maintaining a compact footprint that doesn t sacrifice rigidity. The **28-hole design** provides versatility for frame builders and racers, accommodating a wide range of wheel sizes and spoke patterns, from classic 32mm to modern 28mm or even 25mm for ultra-lightweight wheelsets. The hub s **freehub mechanism** is a refined iteration of Shimano s proprietary technology, featuring a smooth, low-friction engagement that delivers effortless shifting and a near-instantaneous click when pedaling, a hallmark of Ultegra s reputation for reliability and precision. The **8/9/10-speed compatibility** ensures seamless integration with Shimano s latest drivetrain iterations, whether you re running a compact 1x9, a double 1x10, or a traditional 2x10 setup, with the freehub body engineered to handle the increased chainline precision required by modern cassettes. For disc brake systems, the hub incorporates **130mm rotor mounting points**, allowing for the installation of either standard or boost-compatible rotors, depending on the frame s requirements, while the **axle design** ensures compatibility with both traditional quick-release skewers and modern thru-axles for added security and reduced wobble. Built to withstand the rigors of competitive racing and long-distance touring, the FH-F6600 is treated with a durable anodized finish that resists corrosion and wear, ensuring longevity even under the most demanding conditions. Whether paired with aero wheels for speed or deep-section rims for stability, this hub is a testament to Shimano s commitment to pushing the boundaries of performance, offering cyclists a blend of cutting-edge technology and timeless craftsmanship that elevates every ride.
### **Shimano FH-F6600 (Ultegra 8/9/10) 28H 130mm Rear Hub: Pros and Cons**
#### **Pros:**1. **High-End Performance** The FH-F6600 is part of Shimano s Ultegra lineup, offering superior durability, smooth shifting, and reliability compared to lower-tier groupsets. It is built for endurance and performance, making it suitable for road cycling, gravel, and light touring.
2. **Durability and Longevity** Shimano s Ultegra components are known for their robust construction, often outlasting mid-range groupsets. The FH-F6600 s internal bearings and casing are designed to handle heavy use, reducing the need for frequent replacements.
3. **Compatibility with Modern Drivetrains** This hub is compatible with **11-speed** (Ultegra 8/9/10) and **12-speed** (with minor adjustments) systems, making it a versatile choice for upgrading or maintaining a bike with newer Shimano components. It works well with **Ultegra, Dura-Ace, and even some higher-end Deore** setups.
4. **Lightweight Design** At **130mm in width**, it is relatively compact for a 28-hole hub, reducing unsprung weight while still providing ample space for wide tires (up to 45mm on road bikes or 50mm on gravel). This improves efficiency and handling.
5. **Reliable Bearing System** Shimano s sealed cartridge bearings in this hub reduce maintenance needs and improve smoothness. The **dual-route cable entry** (optional) allows for cleaner routing, reducing friction and improving shift quality.
6. **Wide Tire Support** The **28-hole spacing** allows for wider tire clearance, making it suitable for **road bikes, gravel bikes, and light touring** without sacrificing performance. This is particularly useful for riders who want versatility without a full gravel setup.
7. **Backward Compatibility** Works with **Shimano s 105, Ultegra, and Dura-Ace** derailleurs, making it a cost-effective upgrade path if you plan to move up in the future.
8. **Good Value for Ultegra** While not the absolute top-tier (Dura-Ace FH-F7000), the FH-F6600 offers **near-Dura-Ace performance** at a lower cost, making it a smart choice for serious riders who don t need the absolute best.
---
#### **Cons:**1. **Not as Light as Carbon or Entry-Level Hubs** While durable, it is **steel**, which adds weight compared to **carbon fiber hubs** (e.g., Shimano s FH-F8000 or third-party options). For ultra-lightweight racing, this may be a drawback.
2. **Limited Freehub Body Options** Unlike some higher-end Shimano freehubs (e.g., Dura-Ace), the FH-F6600 does **not** have a **12-speed freehub body** natively it is **11-speed only**. If you plan to upgrade to 12-speed later, you may need to replace the freehub body.
3. **Higher Cost Than Mid-Range Hubs** While still reasonable for Ultegra, it is **more expensive** than **Deore or SLX hubs**, which may not justify the upgrade for casual riders.
4. **Potential for Overkill on Budget Setups** If your bike is otherwise equipped with **105 or lower-tier components**, the FH-F6600 may feel **unnecessarily premium**, especially if you don t ride hard enough to fully utilize its capabilities.
5. **Maintenance Still Required** While low-maintenance, **sealed bearings do wear out over time** (typically **100,000 150,000 km** depending on conditions). Replacing them requires removing the hub, which is more involved than with some lower-end models.
6. **No Disc Brake Compatibility (Unless Paired with a Disc Brake Fork)** Unlike some modern hubs, the FH-F6600 is **rim brake only**. If you re running **disc brakes**, you ll need a **disc brake fork** (e.g., Shimano s FH-F7000 or third-party options).
7. **Slightly Bulkier Than Ultra-Light Hubs** At **130mm**, it is wider than some **racing-specific hubs** (e.g., Shimano s FH-F8000 at 120mm), which may affect aerodynamics in time trials or sprinting.
---
### **Conclusion & Recommendation**
The **Shimano FH-F6600 (Ultegra 8/9/10) 28H 130mm rear hub** is an **excellent choice** for riders who want a **high-performance, durable, and versatile** hub without breaking the bank. It strikes a **strong balance between reliability, compatibility, and value**, making it ideal for:
- **Road cyclists** looking to upgrade from 105 or lower-tier setups.
- **Gravel/touring riders** who need **wide tire clearance** without sacrificing shifting quality.
- **Serious riders** who want **Ultegra-level performance** but don t need Dura-Ace s extra refinement.
- **Those planning future upgrades** (11/12-speed compatibility, easy derailleur swaps).
#### **Who Should Avoid It?**
- **Ultra-lightweight racers** who prioritize **carbon hubs** and **120mm width** for aerodynamics.
- **Budget-conscious riders** who can get by with **Deore or SLX** for their needs.
- **Disc brake users** who don t have a **disc brake fork** (though this is more of a setup limitation than a hub flaw).
#### **Final Verdict: Highly Recommended**
If you re building or upgrading a **road, gravel, or endurance bike** with **Shimano s mid-to-high-end drivetrain**, the **FH-F6600 is one of the best all-around choices**. It offers **near-Dura-Ace durability**, **smooth shifting**, and **versatility** at a **reasonable price**, making it a **smart investment** for serious cyclists. Pair it with a **compatible derailleur (Ultegra 8/9/10 or Dura-Ace)** and **wide tires (up to 45mm on road, 50mm on gravel)**, and you ll have a **reliable, high-performance hub** for years.
