This article will provide you with all the essential information you need, from understanding what they are, how they work, and tips for choosing the right cleats. So, grab your cycling gear and let's get started!

What are Shimano PD-M520 Pedals?

So, what exactly are the Shimano PD-M520 pedals? Forget the confusing name for a sec. These are clipless pedals. And no, that doesn't mean you clip them with a clothespin, ha! It means they clip into your cycling shoes using a cleat system. The PD-M520, in particular, is a popular model from Shimano, a well-known brand in the cycling world. These pedals are designed for mountain biking and general cycling, making them versatile for various riding styles and terrains. The Shimano PD-M520 offers a reliable and efficient way to connect your shoes to your bike, allowing for a more effective transfer of power and improved pedaling efficiency. They're built tough, are relatively affordable, and offer a great entry point into the world of clipless pedals. This is a very common upgrade that lots of cyclist would do when they start getting serious about cycling. The ease of use also makes them a top option for both casual riders and those who want to level up their performance on trails or roads.

Benefits of Using Clipless Pedals Like the PD-M520

Now, why would you want to switch from regular flat pedals to something like the Shimano PD-M520? Well, the advantages are pretty significant:

Improved Pedaling Efficiency: Clipless pedals allow you to pull up on the pedals during the upstroke, as well as push down, which engages more muscles and leads to a smoother, more efficient pedal stroke. This can significantly reduce fatigue on long rides and help you climb hills more effectively.
Enhanced Power Transfer: By securely connecting your shoe to the pedal, you can transfer more power to the drivetrain. This means you get more of your effort into moving the bike forward, resulting in increased speed and better acceleration.
Better Bike Control: Clipless pedals offer a more secure connection between you and your bike. This can improve your control, especially on technical trails or during off-road riding, as your feet are less likely to slip off the pedals.
Optimized Foot Positioning: Clipless pedals help you maintain consistent foot positioning, which is crucial for preventing injuries and improving comfort on longer rides. The cleats lock your foot into the ideal position, reducing the risk of your foot sliding around.

So, if you are looking to become a better cyclist and looking to make an upgrade, the Shimano PD-M520 can be a great option.

Understanding the PD-M520's Features and Specifications

Okay, let's get into the nitty-gritty of the Shimano PD-M520. What makes them tick? Here's a breakdown of their key features and specifications.

SPD (Shimano Pedaling Dynamics) System: The PD-M520 uses Shimano's SPD system, which is a two-bolt cleat system. This means your shoes will have two holes to accommodate the cleats that attach to the pedals. The SPD system is known for its reliability and durability.
Open Binding Mechanism: The design of the PD-M520 features an open binding mechanism. This design allows for easy entry and exit, even in muddy or debris-filled conditions. This feature makes it great for mountain biking, where you're likely to encounter a variety of trail conditions.
Adjustable Cleat Retention: The PD-M520 allows you to adjust the tension of the cleat engagement. This means you can customize how easy or difficult it is to clip in and out of the pedals. This is a great feature, especially for beginners who are still getting used to the clipless system.
Durable Construction: These pedals are built to last. They feature a durable chromoly steel axle and a sealed bearing system, which helps protect the internal components from water and dirt. This means you can expect these pedals to withstand a lot of abuse and last for a good amount of time.
Weight: They have a relatively lightweight design, which contributes to overall cycling efficiency and makes them easy to use. The weight is a critical factor for many riders, especially those who are into performance.

The Importance of Compatibility

Before you buy the Shimano PD-M520, it's important to make sure it's compatible with your cycling shoes. The PD-M520 uses the SPD two-bolt cleat system, so you'll need cycling shoes that are designed to accommodate this system. Most mountain biking shoes and many touring/commuting shoes are compatible with SPD cleats. Road cycling shoes typically use a different cleat system (three-bolt), so be sure to check before you buy! Check that your cycling shoes are compatible with the SPD cleat system. Look for shoes that have two-hole mounting patterns on the soles.

How to Install and Use the Shimano PD-M520

Alright, let's get down to the practical stuff: installing and using your new Shimano PD-M520 pedals. It might seem daunting at first, but don't worry, it's pretty straightforward, and with a few simple steps, you'll be clipping in and out like a pro!

Installation Guide

Remove Your Old Pedals: Use a pedal wrench to remove your old pedals from your crank arms. Remember, the left pedal has a reverse thread, so turn it clockwise to loosen it. Apply some grease to the pedal threads to prevent them from seizing. If you are having trouble, you can go to your local bike shop and they can do it for you, at a fee.
Grease the Threads: Apply a small amount of grease to the threads of the PD-M520 pedals. This will help prevent corrosion and make it easier to remove them later.
Install the Pedals: Thread the pedals into the crank arms by hand to avoid cross-threading. Tighten them with a pedal wrench, ensuring they are securely fastened.
Install the Cleats on Your Shoes: Now it's time to install the cleats on your cycling shoes. Locate the cleat mounting points on the sole of your shoes. Use the provided screws to attach the cleats to the shoes, making sure they are aligned correctly. You may need to adjust the cleat position to find the optimal placement for your foot. Some may require a little bit of adjustment to find the right position.

Clipping In and Out

Clipping In: Position your shoe over the pedal and push down firmly. You should hear a distinct click, indicating that the cleat is engaged. Practice clipping in and out a few times in a safe environment, such as on grass, before heading out on the road or trail. Get used to the feel.
Clipping Out: To release your foot, rotate your heel outwards. The cleat should disengage from the pedal with a click. It might take a bit of practice to get used to this motion, but it will become second nature in no time.

Tips for Beginners

Start in a Safe Environment: Practice clipping in and out in a grassy area or indoors before hitting the road or trails. This will give you the chance to get comfortable with the system.
Adjust the Cleat Tension: Set the cleat retention to a low setting initially, making it easier to clip in and out. As you get more comfortable, you can increase the tension. This will prevent you from accidentally uncliping in crucial moments.
Look Ahead: Always look ahead, especially when approaching intersections or obstacles. This will help you anticipate when you need to unclip.
Practice, Practice, Practice: The more you use clipless pedals, the more natural it will feel. Don't get discouraged if you have a few wobbles or falls in the beginning. It's all part of the learning process!

Maintaining Your Shimano PD-M520 Pedals

Proper maintenance will extend the life of your Shimano PD-M520 pedals and ensure they continue to perform optimally. Here's a quick guide to keeping them in tip-top shape.

Cleaning and Lubrication

Regular Cleaning: Clean your pedals regularly, especially after riding in muddy or wet conditions. Use a brush and soapy water to remove dirt and debris.
Lubrication: Periodically lubricate the pedal's binding mechanism with a light oil or grease. This will help keep them operating smoothly.
Inspect and Replace: Inspect the pedals for any signs of wear and tear, such as damaged cleats or worn bearings. Replace any worn components as needed. Keep an eye on the cleats as these parts need to be replaced after a period of time.

Cleat Care

Clean Your Cleats: Clean your cleats regularly to remove dirt and debris. This will help them engage with the pedals more easily.
Inspect for Wear: Check your cleats for wear and tear. Replace them when they become worn to ensure proper engagement and prevent premature wear on the pedals. Worn cleats can make it difficult to clip in and out and can reduce power transfer efficiency.
Lubricate Your Cleats: Apply a small amount of lubricant to the cleats and pedals to reduce friction and make clipping in and out smoother.

Choosing the Right Cleats for Your Shimano PD-M520

The choice of cleats is critical for a good experience with your Shimano PD-M520. The correct cleats will ensure proper engagement and prevent premature wear. Shimano typically includes cleats with the pedals, but you may need to replace them over time or choose different cleats based on your needs.

Cleat Options

SH51 Cleats: These are the standard cleats that usually come with the PD-M520 pedals. They offer a secure connection and are designed for general cycling use. They allow for some degree of lateral float, which can reduce strain on your knees.
SH56 Cleats: These cleats provide a multi-directional release, making it easier to unclip in emergency situations. This makes them a great option for beginners or anyone who prioritizes easy disengagement. These are a good alternative if you are just starting and want a little bit more of ease when unclipping.

Cleat Installation and Adjustment

Proper Placement: Correct cleat placement is vital for optimal comfort and power transfer. The position of the cleat affects your foot's position in relation to the pedal.
Fine-Tuning: Fine-tune your cleat position to match your personal riding style. Consider the position of your foot and how it relates to your knee and ankle alignment.
