Decoding Pedal Systems: SPD vs Delta for Peloton

The Peloton bike comes with two different types of pedal systems: SPD and Delta. These are the standard pedals that come with the bike and they each have their own unique set of features and benefits.

In this article, we will be exploring the differences between these two pedal options and helping you decide which one is right for you. So, let’s dive in!

What is the basic difference between SPD vs Delta?

The main difference between SPD vs Delta pedals is the type of cleat that each system uses. The SPD pedal system uses a 2-bolt cleat, while the Delta system uses a 3-bolt cleat. This may seem like a small difference, but it has a significant impact on your riding experience.

One of the biggest factors to consider when choosing between SPD vs Delta pedals is compatibility. The Peloton bike comes with a set of SPD pedals, which means any shoes that are compatible with this type of cleat can be used on the bike.

However, if you want to switch to Delta pedals, you will need to purchase a separate set and make sure you have shoes that are compatible with the 3-bolt cleat. Keep in mind that not all cycling shoes are compatible with both types of pedals, so it’s important to double-check before making a purchase. 

Comfort and Efficiency

Both SPD and Delta pedals offer a secure connection between your foot and the pedal, providing more control and stability while riding. However, many cyclists argue that Delta pedals offer better power transfer and efficiency due to the larger surface area of the cleat.

Additionally, Delta pedals tend to have a wider platform, providing more support for your foot during longer rides. On the other hand, SPD pedals are often praised for their ease of use and comfort, making them a popular choice among beginners or those who prioritize convenience over performance. 


Another significant difference between SPD vs Delta pedals is the ability to adjust the tension of the cleats. With SPD pedals, you can easily adjust the tension using a small wrench, making it easy to find your preferred level of float (the degree to which your foot can move while clipped in).

However, Delta pedals do not offer this option for adjustment, which may be a drawback for some riders.  


When it comes to cost, SPD pedals tend to be more budget-friendly compared to Delta pedals. This is because they are a more basic and commonly used pedal system, making them easier to manufacture and purchase.

However, if you already have Delta-compatible shoes or prefer the features of Delta pedals, the extra cost may be worth it for you.

Are SPD and Delta the same?

In short, no. Despite their similar appearance and shared use of a clip-in mechanism, SPD and Delta pedals are not interchangeable. As mentioned previously, they each use a different type of cleat and have varying levels of adjustability, comfort, and efficiency. It’s important to carefully consider your own riding preferences before choosing between the two options.  

SPD Pedals In-Depth Look

Now that we have a basic understanding of the differences between SPD vs Delta pedals, let’s take a closer look at the features and benefits of each. First up, SPD pedals.

SPD stands for “Shimano Pedaling Dynamics” and was developed by the cycling brand Shimano in the 1990s. They quickly became popular among cyclists due to their ease of use and versatility.

Features and Benefits

  • Two-bolt cleat system
  • Adjustable tension for preferred level of float
  • Comfortable and easy to use
  • Budget-friendly

One of the main benefits of SPD pedals is their versatility. They can be used for a variety of cycling activities, from indoor spinning classes to outdoor road rides. This makes them a great option for beginners or those who participate in different types of cycling.


SPD pedals are celebrated for their universal two-bolt cleat system, allowing for widespread compatibility with many indoor cycling shoes. This universality means that you’re more likely to find shoes that can accommodate SPD cleats whether you’re shopping at a specialty bike shop or a general sports store.

When considering the plethora of options available, SPD pedals stand out as an adaptable choice for fitness enthusiasts who have a preference for indoor cycling classes such as those offered by Peloton.


Beyond their compatibility with indoor cycling attire, SPD pedals boast a versatility that stretches to the realm of outdoor biking. Many riders opt for SPD pedals not only on their stationary bikes but also on their outdoor bikes, appreciating the seamlessness of using the same shoes and cleats across different cycling activities.

The durable design of SPD pedals handles the rigors of both environments, making it a go-to choice for cyclists who demand a pedal that can keep up with varied cycling demands.

Delta Pedals In-Depth Look

Following our exploration of SPD pedals, let’s now delve into Delta pedals, which present a unique value proposition for Peloton users.

Specialized Design:

Delta pedals are a proprietary pedal system that was specifically constructed with the Peloton experience in mind. Their design is tailored to harness the full potential of Peloton’s high-performance stationary bikes, meaning they’re optimized to complement the exact specifications and ride quality that Peloton adherents have come to value.

Features and Benefits:

  • Three-bolt cleat system
  • Wider platform for increased foot support
  • Optimized for power transfer and performance
  • Peloton-specific design

Delta pedals provide a broader platform than their SPD counterparts, which is particularly beneficial when it comes to the rider’s stability on the bike. The increased contact area with the cleat not only offers superior stability during intense workouts but also augments power transfer. This means each pedal stroke is more effective, pushing you towards your fitness goals with greater efficiency.

Enhanced Stability:

Thanks to Delta’s three-bolt cleat design, riders experience a more anchored connection to the pedal, which promotes an increased sense of security and leverage. This design is ideal for riders prioritizing performance, as the firm link minimizes power loss during the transfer between foot and pedal, ensuring each pedal stroke propels you with maximal force.


Choosing Delta pedals means committing to a system that has been developed for an immersive Peloton journey. However, it’s essential to ensure your cycling footwear is compatible with the three-bolt cleat system, as it is distinctly different from the two-bolt system used by SPD pedals.

While Delta pedals may require a specific shoe type, they are an excellent investment for die-hard Peloton users who are seeking to maximize their performance and enjoy a seamless, stability-focused ride.

Which Pedal System is Right for You?

At the end of the day, the answer to this question depends on your personal preferences and riding style. If you prioritize convenience, comfort, and compatibility, SPD pedals may be a better option for you. On the other hand, if you are looking for maximum power transfer and efficiency, Delta pedals might be worth the investment.

Regardless of which pedal system you choose, it’s important to remember that proper bike fit and cleat alignment are essential for a comfortable and efficient ride. So, be sure to consult with a professional or do some research on how to properly set up your pedals for the best riding experience. 

Additional Tips for Peloton Riders

  • If you are a beginner or new to cycling, starting with SPD pedals may be a good choice to get used to clipping in and out. You can always switch to Delta pedals later on if you feel the need for an upgrade.
  • Consider investing in a pair of cycling shoes specifically designed for indoor cycling, as they often have stiffer soles and better ventilation for a more comfortable ride.
  • Whichever pedal system you choose, regular maintenance and replacing worn-out cleats are essential for optimal performance and safety on your Peloton rides.  So, don’t forget to check and replace your cleats periodically.
  • Don’t be afraid to experiment with different types of pedals and cleats to find the best fit for you. Every rider is different, and what works for one person may not work for another.
  • Lastly, always remember to listen to your body and make adjustments as needed. Your comfort and safety should always be the top priority when it comes to any athletic activity. Happy riding!

Probs and Cons of SPD and Delta Pedals

Here’s a quick summary of the pros and cons of both SPD and Delta pedals to help you make your decision:

Pedal TypeProsCons
SPD Pedals– Universal compatibility– Smaller contact area with the cleat may not be as stable for intense workouts
– Versatile for both indoor and outdoor cycling activities– Can lead to hot spots or discomfort on longer rides
