Review SHIMANO Ultegra Clipless Pedals 9/16 No Cleats

The **Shimano PD-R6620 Ultegra SPD-SL Cleat Pedals** represent the pinnacle of precision engineering and performance in road cycling, designed for riders who demand both speed and reliability without compromise. These pedals are the latest iteration of Shimano s elite Ultegra lineup, crafted from a lightweight yet robust **aerospace-grade aluminum alloy** that ensures durability while minimizing weight critical for climbers and time trialists alike. The **9/16" x 20 thread standard** ensures compatibility with a wide range of road and gravel bikes, from carbon-fiber frames to high-end steel or titanium builds, making them a versatile choice for serious cyclists. The **SPD-SL cleat system** is a masterclass in ergonomic design, featuring a **low-profile, asymmetrical shape** that optimizes power transfer while reducing knee strain. The cleat s **angled, three-point attachment** distributes force evenly across the foot, allowing for a more natural pedal stroke and enhanced efficiency, whether you're sprinting on the flats or digging deep in a grueling ascent. The **smooth, one-piece cleat design** eliminates the need for adjustment, ensuring a consistent fit every time you clip in, while the **durable rubber gasket** provides a secure yet comfortable seal against dirt and debris, a common nuisance on long rides or in competitive races. For riders who prioritize performance, the **SPD-SL system** also offers a **quick-release mechanism** that allows for effortless unclipping in emergencies, a feature that can be invaluable in high-speed situations or when navigating technical terrain. The pedals themselves boast a **sleek, aerodynamic profile**, reducing drag and enhancing efficiency at high speeds, while the **precision-machined spindle** ensures minimal wobble and maximum power transfer. Whether you're chasing a personal best in a criterium, tackling the grueling climbs of the Alps, or simply seeking the ultimate in cycling performance, the **PD-R6620 Ultegra pedals** deliver the perfect blend of technology, comfort, and reliability to elevate your ride. Built to withstand the demands of elite competition, these pedals are not just an accessory they re a cornerstone of a high-performance setup.

The **Shimano PD-R6620 Ultegra clipless pedals** with **9/16" x 20mm cleats** are a mid-range option in Shimano s clipless pedal lineup, offering a balance between performance and affordability. Below is a detailed breakdown of their pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Performance-Oriented Design**

The PD-R6620 is part of Shimano s Ultegra series, which prioritizes cycling performance. It features a **stiffer carbon fiber body** compared to lower-tier models, reducing flex and improving power transfer. The **SPD-SL cleat system** (compatible with 9/16" x 20mm cleats) is optimized for road cycling, offering a secure and responsive connection between rider and bike.

2. **Lightweight Construction**

At approximately **220 grams per pair**, these pedals are relatively light for their class, reducing rotational mass and improving pedal efficiency. The carbon fiber shell contributes to this weight savings without sacrificing rigidity.

3. **Durability and Build Quality**

Shimano s Ultegra components are known for their robustness. The PD-R6620 features a **durable carbon fiber body** and **stainless steel pins**, which are resistant to corrosion and wear. The cleat retention system is also reliable, though not as premium as higher-end models like the Dura-Ace.

4. **Compatibility with SPD-SL Cleats**

The pedals are fully compatible with **Shimano SPD-SL cleats**, including the **9/16" x 20mm standard**. This means you can use them with a wide range of cleats from Shimano and third-party brands (e.g., Look, SPD-SL clones). The cleat interface is smooth and precise, reducing lateral movement during pedaling.

5. **Moderate Price Point**

Compared to Shimano s top-tier Dura-Ace pedals (e.g., PD-R9100), the R6620 offers a **cost-effective alternative** without sacrificing too much performance. Priced lower than carbon-fiber road pedals from competitors like Look or Speedplay, it provides good value for serious cyclists who aren t ready to invest in the highest-end options.

6. **Adequate Float Angle**

The SPD-SL system offers **4 degrees of float**, which is sufficient for most road cyclists. This allows for natural foot positioning without excessive strain, though riders with very specific biomechanics might prefer the 6-degree float of higher-end systems.

7. **Easy to Clean and Maintain**

The carbon fiber body is easy to wipe down, and the stainless steel pins resist rust. Shimano s SPD-SL cleats are also straightforward to remove and replace if needed.

8. **Compatibility with Shimano Di2**

If you re using Shimano s electronic shifting system (Di2), the R6620 pedals are fully compatible, though they don t include Di2-specific features like the PD-R9100 does (e.g., pedal power sensors).

---

### **Cons**

1. **Not as Light as Entry-Level or Budget Options**

While the R6620 is lightweight for its class, it is **heavier than some entry-level carbon pedals** (e.g., Shimano s PD-M5100 or PD-R3000). If weight is a critical factor for you (e.g., time trial or sprinting), you might prefer even lighter options.

2. **Limited Float Compared to Higher-End Systems**

The **4-degree float** is standard for SPD-SL, but some riders (particularly those with specific foot shapes or injuries) may find it restrictive. Higher-end systems like Dura-Ace or Look Keo offer **6-degree float**, which can provide a more natural feel.

3. **No Pedal Power Sensor**

Unlike the **PD-R9100 (Dura-Ace)**, the R6620 does not include a **built-in power meter**. If you re interested in tracking power output, you d need to pair these with a separate sensor (e.g., SRM, PowerTap) or use a different pedal model.

4. **Durability Concerns Over Time**

While the carbon fiber body is sturdy, **intense use (e.g., gravel, mountain biking, or aggressive riding)** could lead to wear or damage over time. The cleat retention system is reliable, but the pins may eventually wear out and require replacement.

5. **Less Premium Feel Than Higher-End Models**

The R6620 lacks some refinements found in the **Dura-Ace PD-R9100**, such as a **smoother cleat engagement** and a more polished finish. The entry point is slightly less refined, though this is negligible for most casual to intermediate riders.

6. **Compatibility Issues with Non-Shimano Cleats**

While the 9/16" x 20mm SPD-SL cleats are widely compatible, some **third-party cleats** (especially cheaper or poorly made ones) may not fit as securely or last as long as Shimano s own cleats.

7. **No Built-In LED Lights**

Unlike some higher-end pedals (e.g., Shimano s PD-R9100 with optional LED lights), the R6620 does not include lighting functionality. If you ride in low-light conditions, you may need to add aftermarket lights.

---

### **Conclusion**

The **Shimano PD-R6620 Ultegra pedals** are an excellent choice for **road cyclists** who want a **high-performance, durable, and reasonably lightweight** clipless pedal without breaking the bank. They strike a balance between **performance, build quality, and affordability**, making them suitable for:

- **Intermediate to advanced road cyclists** who want Ultegra-level components.

- Riders who prioritize **power transfer and stiffness** over ultra-lightweight or premium features.

- Those who already use Shimano s SPD-SL system and want a reliable upgrade.

However, if you re a **serious time trialist, gravel rider, or power meter user**, you might find the **PD-R9100 (Dura-Ace)** or other premium pedals (e.g., Look Keo V-Slam) more appealing. Similarly, if **float or weight** is a critical factor, you may need to look elsewhere.

---

### **Recommendation**

- You re a road cyclist looking for a **high-quality, stiff, and reliable** clipless pedal.

- You already use or plan to use **Shimano SPD-SL cleats** (9/16" x 20mm).

- You want **Ultegra-level performance** without the price of Dura-Ace.

- You don t need **extra float, power metering, or lighting**.

- You want **more float** (e.g., Dura-Ace PD-R9100 or Look Keo).

- You prioritize **ultra-lightweight pedals** (e.g., Shimano PD-R3000 or carbon road-specific pedals).

- You need **built-in power metering** (e.g., Shimano PD-R9100 with Di2 power sensor).

- You ride in **low-light conditions** and want integrated lights.

**Final Verdict:** The PD-R6620 is a **solid, well-rounded choice** for most road cyclists, offering great value and performance. If you re in the Ultegra ecosystem, these pedals are a no-brainer upgrade from lower-tier models.
