What are Shimano PD-M520 Pedals?

So, what exactly are we talking about when we say Shimano PD-M520? Well, they're clipless mountain bike pedals. That means they use a mechanism that allows your cycling shoes to clip directly into the pedal, providing a more efficient and powerful pedaling experience. Shimano, a globally renowned name in the cycling industry, designed these pedals with a focus on durability, ease of use, and versatility. They're designed for riders who enjoy trail riding, cross-country, and even light touring. The PD-M520 is a step up from entry-level clipless pedals, offering a noticeable improvement in performance and build quality. They are made to be used with the SPD cleat system (Shimano Pedaling Dynamics), which is a very well-known and trustworthy system in the cycling world. These pedals have gained a reputation for being super reliable and are frequently recommended for new riders. They’re a fantastic starting point if you're new to clipless pedals. The PD-M520 pedals are designed with a dual-sided design, so you can clip in from either side, which is super convenient. They also feature adjustable tension, which allows you to customize how easy or hard it is to clip in and out. This is a game-changer because you can adjust the tension to match your skill level and riding style. Whether you are a beginner looking for an easy release or an experienced rider who prefers a secure connection, these pedals can be adjusted to your liking. In essence, the Shimano PD-M520 pedals are a popular choice for mountain bikers of all levels because they are durable, easy to use, and offer a great value proposition.

Key Features and Specifications

Let's break down some of the key features and specs of the Shimano PD-M520 pedals. Understanding these details will help you grasp what makes them a solid choice. Firstly, they use the SPD cleat system, which, as we mentioned earlier, is known for its reliability and efficient power transfer. The body of the pedal is made from forged alloy, providing excellent strength and durability, able to withstand the rigors of off-road riding. The axle is made from durable Chromoly steel, which is another guarantee of durability and long-term use. This material choice allows the pedals to handle the bumps and hits that come with trail riding. The sealed bearing system is another important feature, shielding the internal components from dirt and water. This is crucial for longevity, as it prevents contamination that can lead to premature wear and tear. One of the standout features is the adjustable entry and release tension. This allows you to fine-tune the amount of force needed to clip in and out. This adjustability is great for riders of all experience levels. The pedals have a dual-sided design, so you can clip in from either side, which is useful when you're starting and stopping frequently on the trail. The PD-M520s also offer a good amount of platform area around the cleat. This added surface area helps distribute pressure and provide more support when you're not clipped in. This can be especially helpful when navigating tricky sections of trail or when you just want a bit more stability. The weight of each pedal is around 190 grams, making them reasonably lightweight without compromising on durability. The pedals also come with the necessary cleats (SM-SH51 cleats), making it convenient to get started right away. Overall, the Shimano PD-M520 pedals offer a great blend of features, durability, and performance, making them a top pick for mountain bikers looking for a reliable clipless pedal.

Benefits of Using Shimano PD-M520 Pedals

Alright, let’s talk about the good stuff! Why should you consider the Shimano PD-M520 pedals? There are several key benefits that make them a popular choice. First and foremost, clipless pedals, in general, offer a significant improvement in pedaling efficiency. By connecting your shoe directly to the pedal, you can pull up on the upstroke, which is a big change from flat pedals where you can only push down. This more efficient pedaling motion allows you to generate more power with each stroke. This can translate to faster speeds, less fatigue, and improved climbing ability. The PD-M520 provides a secure connection, which leads to better power transfer. Every watt you put into the pedals is converted into forward momentum. This is a major advantage, especially on challenging climbs and technical terrain. Another great benefit of these pedals is the improved control and bike handling. When you are clipped in, your feet are more securely connected to the bike, which allows for better control, especially on rough or uneven terrain. This increased control can boost your confidence and allow you to tackle more challenging trails. The adjustable tension on the PD-M520 allows you to customize the release force. This is particularly helpful for beginners who might want an easier release to avoid falls. As you become more experienced, you can increase the tension for a more secure feel. Durability is another major advantage. Shimano is known for producing high-quality components, and the PD-M520 pedals are no exception. They are designed to withstand the wear and tear of mountain biking, with a robust build that ensures longevity. This means they will last you a long time. The dual-sided design is a practical feature, as it allows for easy clipping in, regardless of which side is up. This is a big help when you're starting and stopping, or if you're not sure which side is facing up. The Shimano PD-M520 pedals offer a great value for the price. They provide a high level of performance and durability without breaking the bank, which makes them an accessible upgrade for many riders. In summary, the benefits of the Shimano PD-M520 pedals include enhanced pedaling efficiency, increased power transfer, improved control, adjustable tension, durability, and ease of use. These pedals provide a significant upgrade for mountain bikers of all levels.

Installing and Maintaining Your PD-M520 Pedals

So, you’ve decided to get the Shimano PD-M520 pedals? Awesome! Now, let’s get into the nitty-gritty of installation and maintenance. Don’t worry, it’s not as complicated as it sounds. You’ll need a few tools: a pedal wrench (or a 15mm wrench), grease, and the cleats that came with your pedals and the shoes they should be installed on. Before you start, make sure your bike is stable. You can place it on a repair stand or lean it against a wall. The first step is to remove your old pedals. Remember that the left pedal has a reverse thread, so turn it clockwise to loosen. The right pedal has a standard thread, so turn it counter-clockwise to loosen. Once the old pedals are off, clean the crank arm threads with a brush or cloth. Apply a thin layer of grease to the threads of your new PD-M520 pedals. This will help prevent seizing and make it easier to remove them later. Thread the pedals into the crank arms by hand to start. Then, use your pedal wrench to tighten them securely. For the left pedal, tighten counter-clockwise, and for the right pedal, tighten clockwise. Make sure they are tight but don't overtighten. Over-tightening can damage the crank arms. Next, you will need to install your cleats onto your cycling shoes. The SM-SH51 cleats typically come with the pedals. Align the cleat with the sole of your shoe. There is usually a cleat alignment guide that helps you. Once aligned, tighten the cleat bolts. It is best to start by loosely attaching the cleat to the shoe, making some adjustments to find the right position, and then tightening it down. The position of the cleats is critical for comfort and performance. Start with the cleats in a neutral position (centered). Then, experiment with moving them forward or back, or adjusting the angle, until you find the sweet spot. Once the pedals and cleats are installed, make sure to adjust the tension on the pedals. Use the tension adjustment screw located on the pedal body to control how easy or hard it is to clip in and out. Start with a lower tension setting if you’re new to clipless pedals. After each ride, check your pedals and cleats for any signs of wear or damage. Clean your pedals regularly to remove any dirt or debris. To maintain the longevity of your Shimano PD-M520 pedals, apply grease to the pedal threads and the axle. This will prevent corrosion and ensure smooth operation. With a little care and attention, your Shimano PD-M520 pedals will provide years of reliable service. Following these steps will ensure that you have your pedals set up correctly and running smoothly!

Troubleshooting Common Issues with PD-M520

Even the best gear needs a little TLC from time to time. Here's how to troubleshoot some common issues you might encounter with your Shimano PD-M520 pedals, so you can keep on riding! One common issue is difficulty clipping in or out. If it’s hard to clip in, try loosening the tension adjustment screw on the pedal. If it’s hard to clip out, the opposite applies - loosen the screw. If the problem persists, check your cleats for wear or damage and make sure they are installed correctly. Another problem might be that the pedals don't feel secure or have excessive play. This can be caused by worn cleats or loose bolts. Inspect your cleats for any signs of wear and replace them if necessary. Check the cleat bolts on your shoes to ensure they are properly tightened. Also, you can inspect the pedal body for excessive movement or play. If you find your pedals are squeaking, this often means that the pedal and cleat interface needs some lubrication. Apply a small amount of chain lube or dry lubricant to the contact points between the pedal and cleat. Another problem that might pop up is that one side of the pedal seems to work better than the other. This can be due to a difference in tension settings or cleat positioning. Check the tension on both pedals and make sure it is balanced. Re-adjust the cleat position on your shoes. Make sure that both cleats are aligned the same way. Sometimes, you may experience difficulty clipping in after riding in muddy or dirty conditions. Dirt and debris can accumulate in the pedal mechanism, preventing proper engagement. Clean your pedals thoroughly after each muddy ride. Use a brush or compressed air to remove any dirt. Avoid using high-pressure water, as it can force water into the pedal bearings. If you’re experiencing persistent issues, inspect the pedal bearings. If you notice any roughness or play, it might be time to replace the bearings or the entire pedal. Remember, regular maintenance and attention to detail will help to prevent these problems from happening in the first place. If you're encountering persistent problems, it may be best to consult a professional bike mechanic. By taking these troubleshooting tips into account, you can keep your Shimano PD-M520 pedals running smoothly and enjoy a hassle-free riding experience.

They are a bit more expensive than the PD-M520. Time ATAC pedals are another option, known for their easy entry and release. The Time ATAC pedals offer adjustable tension and excellent mud shedding capabilities. They’re a good choice for riders who want a more forgiving pedal. They tend to have a slightly wider platform than the PD-M520. They are often more expensive as well. When choosing between these options, consider factors like your budget, the type of riding you do, and your personal preferences. The Shimano PD-M520 is an excellent choice for riders who want a reliable, durable, and versatile clipless pedal at a great price. It is best suited for mountain biking, trail riding, and cross-country riding. If you want the lightest possible setup, the Eggbeaters might be a good fit.
