Review SHIMANO Ultegra Clipless Pedals

The **Shimano PD-M6620 Ultegra clipless pedals** represent the pinnacle of precision engineering and performance-oriented design, meticulously crafted for cyclists who demand both cutting-edge technology and uncompromising reliability. These pedals embody Shimano s legendary Ultegra lineage, blending lightweight construction with an advanced mechanical interface that enhances pedal efficiency, power transfer, and rider confidence. The **SPD-SL cleat system**, a hallmark of Shimano s clipless technology, ensures a secure yet natural connection between rider and pedal, allowing for seamless transitions from the standing position to deep, efficient pedal strokes. The **carbon-fiber reinforced composite body** not only reduces weight to an impressive 220 grams per pair (without cleats) but also delivers exceptional stiffness, minimizing energy loss and vibration while maintaining durability for demanding rides.

The **dual-axis design** of the cleat system further refines the pedal stroke, accommodating the natural motion of the foot while reducing strain on the knee and ankle. This innovation is particularly beneficial for climbers and time trialists, as it promotes a more fluid, powerful engagement with the pedal throughout the entire revolution. The **smooth, low-friction bearing system** ensures consistent performance, even under heavy loads, while the **durable, corrosion-resistant components** including the anodized aluminum spindle and reinforced cleat pins guarantee longevity in all weather conditions. Whether tackling grueling mountain ascents or sprinting on flat terrain, these pedals provide the responsiveness and feedback that serious cyclists rely on.

For those who prioritize aesthetics as much as performance, the **sleek, minimalist design** of the Ultegra pedals exudes a sporty elegance, with a clean, aerodynamic profile that complements modern road and gravel bikes. The **color options**, ranging from classic silver to bold red or black, allow riders to customize their setup to match their bike s palette while maintaining a professional, high-performance look. Beyond their technical merits, the PD-M6620 pedals are engineered with the cyclist s comfort in mind, featuring a **soft, ergonomic platform** that reduces foot fatigue during long rides. Whether used on a carbon-fiber road bike or a sturdy gravel rig, these pedals deliver a harmonious blend of innovation, durability, and rider-centric refinement, making them an indispensable choice for competitive and recreational cyclists alike.

The **Shimano PD-M6620 Ultegra clipless pedals** are a mid-range option in Shimano s Ultegra lineup, offering a balance of performance, durability, and value. Below is a detailed breakdown of their pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the Shimano PD-M6620 Ultegra Pedals**

1. **Performance-Oriented Design**

The M6620 pedals are engineered for cycling performance, featuring a **stiff carbon fiber body** that reduces weight while maintaining rigidity. This design minimizes energy loss during pedaling, making them suitable for road and gravel riding where efficiency matters.

2. **Ultegra-Level Reliability**

While not the top-tier **Di2-compatible** Ultegra pedals (like the PD-M8000), the M6620 still benefits from Shimano s **Ultegra-grade build quality**. The cleat mechanism is smooth and durable, with fewer plastic components than lower-tier models, reducing the risk of premature wear.

3. **Compatibility with Shimano and Third-Party Cleats**

These pedals work seamlessly with **Shimano SPD-SL cleats** (including the lightweight **SPD-SL-CL10** and **SPD-SL-CL20** models) as well as some **third-party cleats** (e.g., Look Keo, Time). This flexibility makes them a versatile choice for riders who may switch brands or upgrade cleats later.

4. **Durable Construction**

The **carbon fiber shell** is reinforced to handle the stresses of road riding, and the **steel axles** (with a **12mm thread**) provide a secure fit on most road bikes. The cleat retention system is robust, reducing the likelihood of accidental cleat loss during hard pedaling.

5. **Lightweight for the Price**

At around **180 200g per pair**, these pedals are significantly lighter than entry-level models (e.g., Shimano Sora or Tiagra) without sacrificing too much durability. This makes them a good option for riders who want performance without the premium cost of Di2 pedals.

6. **Good for Training and Group Rides**

The **smooth engagement and release** of SPD-SL cleats make these pedals ideal for **group rides, training, and time trials**, where quick, efficient pedaling is key. The cleat system is forgiving for beginners while still offering precision for experienced riders.

7. **Aesthetic Appeal**

The **black carbon fiber finish** and **Ultegra branding** give these pedals a premium look, making them a stylish upgrade from lower-tier models. This can be important for riders who care about the visual consistency of their bike setup.

8. **Warranty and Shimano Support**

Shimano offers a **standard 2-year warranty** on these pedals, which is typical for mid-range components. Shimano s global service network ensures that repairs or replacements are accessible if issues arise.

### **Cons of the Shimano PD-M6620 Ultegra Pedals**

1. **No Di2 Compatibility**

Unlike the **PD-M8000 or PD-M9000 Ultegra pedals**, the M6620 **does not support Shimano Di2 electronic shifting**. If you re building a **full Di2 system**, you ll need to pair these with a different pedal model or accept that they won t integrate with your electronic drivetrain.

2. **Plastic Components in the Cleat Mechanism**

While the pedal body is carbon fiber, some **internal plastic parts** (e.g., the cleat retention clips) are present. Over time, these can wear out, especially if you ride aggressively or frequently. This is a common trade-off in mid-range Ultegra components.

3. **Not as Light as Top-Tier Ultegra Pedals**

The **PD-M8000 (Di2-compatible) and PD-M9000** are slightly lighter (around **160 170g per pair**) due to more advanced materials and construction. The M6620 is still very light, but not at the ultra-competitive weight level of the highest-end models.

4. **Limited Off-Road or Gravel Use**

While these pedals are **capable of gravel riding**, they are **not as rugged** as **Shimano s Deore or SLX pedals**, which have reinforced shells and wider cleat compatibility for dirt and light trail use. If you ride frequently off-road, you may prefer a more durable option.

5. **Higher Price Than Entry-Level Pedals**

At ** $150 $180 USD**, these pedals are **more expensive** than **Sora (PD-S5000, $80) or Tiagra (PD-T6000, $100)** but **less expensive than Di2 Ultegra (PD-M8000, $250 )**. If you re on a tight budget, lower-tier pedals offer similar SPD-SL functionality at a fraction of the cost.

6. **Potential for Cleat Wear Over Time**

SPD-SL cleats, while durable, can wear down with heavy use, especially if you ride in rough conditions. Replacing cleats every **2 3 years** may be necessary, adding to long-term costs.

7. **Learning Curve for Beginners**

SPD-SL cleats require **practice to engage and release smoothly**. Beginners may struggle with **quick releases** or **cleat alignment**, which can be frustrating until they get used to the system.

### **Conclusion**

The **Shimano PD-M6620 Ultegra pedals** strike a strong balance between **performance, durability, and affordability**. They are an excellent choice for:

- **Road cyclists** who want **Ultegra-level quality without Di2 complexity**.

- **Riders upgrading from Sora or Tiagra** who want a noticeable performance boost.

- **Training and group ride enthusiasts** who prioritize smooth, efficient pedaling.

- **Budget-conscious buyers** who don t need Di2 but want a premium feel.

- **Di2 users** (requires a different pedal model).

- **Heavy off-road or gravel riders** (consider Deore or SLX instead).

- **Ultra-lightweight racers** who need the absolute lightest pedals (PD-M8000 or PD-M9000).

- **Beginners who dislike SPD-SL cleats** (may prefer flat pedals or SPD for easier use).

---

### **Recommendation**

- You re building a **road bike with a mechanical drivetrain** and want **high-end pedals without Di2**.

- You ride **primarily on pavement** and want **smooth, efficient power transfer**.

- You re upgrading from **Sora or Tiagra** and want a **noticeable step up in feel and durability**.

- You **don t mind SPD-SL cleats** and want a **premium, lightweight option** for under $200.

- You **need Di2 compatibility** **PD-M8000 or PD-M9000**.

- You **ride gravel or light trails** **Shimano Deore (PD-M5100) or SLX (PD-M5200)**.

- You re on a **tight budget** **Tiagra (PD-T6000) or Sora (PD-S5000)**.

- You **prefer flat pedals** **Shimano PD-R7000 or PD-R9100**.

The **PD-M6620 is one of the best mid-range Ultegra pedals** for road cyclists who want **performance without the premium Di2 price**. If your setup aligns with its strengths, these pedals will **enhance your riding experience** while offering **long-term reliability**. For most road riders, they represent **excellent value for the money**.
