Look Keo Pedal Teardown and Bearing Replacement
One of my viewers sent in a set of Look Keo Blade pedals for a Hambini style teardown. Thanks to Paul of Shimano reaming fame for these.
Pedals might often be overlooked in the grand scheme of cycling components, but for dedicated cyclists, their importance is undeniable. The Look Keo Blade pedals have earned a reputation for their cutting-edge design and performance enhancements. In this post, we’ll conduct a detailed teardown of these pedals, examining the technology and engineering that set them apart.
Dissecting Pedal Technology: From Basics to Advanced Engineering
Pedal technology has evolved significantly, moving from simple platforms to intricate systems designed to enhance power transfer, comfort, and efficiency. Look has been at the forefront of this evolution. The Keo Blade pedals exemplify their commitment to innovation and performance.
Core Components and Innovations
Carbon Blade Mechanism
At the heart of the Look Keo Blade pedals is the carbon blade mechanism. Unlike traditional coil springs, the Keo Blade employs a carbon fiber blade to provide tension. This component is crucial for engagement and release, offering a secure and consistent experience. The use of carbon fiber not only improves reliability but also reduces weight, an important factor for performance cycling.
Aerodynamic and Lightweight Design
The Keo Blade pedals are designed with aerodynamics in mind. The streamlined shape reduces drag, which is critical in competitive cycling. Additionally, the pedals are constructed to be lightweight, minimizing energy expenditure during long rides and climbs. This combination of aerodynamic efficiency and weight reduction is a key focus in their design.
Power Transfer Efficiency
Effective power transfer is essential for performance. The Keo Blade pedals feature a large contact surface area, which ensures that the power from the rider is transmitted efficiently to the drivetrain. This design reduces energy loss and provides a stable platform, which is beneficial for both sprinting and long-distance rides.
Adjustable Tension
The Keo Blade pedals allow for adjustable tension settings. This feature is particularly important for riders with different preferences for pedal engagement and release force. Whether a rider prefers a lighter release or a firmer engagement, the adjustable settings can be fine-tuned to meet individual needs.
Durability and Maintenance
Durability is a critical aspect of any cycling component. The Keo Blade pedals are built to withstand rigorous use and adverse conditions. Constructed with high-quality materials and sealed bearings, they require less maintenance and have a longer lifespan. This durability ensures consistent performance over time.
Detailed Teardown and Analysis
To understand what makes the Keo Blade pedals stand out, let’s break down their construction and components.
- Carbon Blade Spring: The carbon blade acts as the tension mechanism, replacing traditional metal springs. This innovative use of carbon fiber enhances durability and reduces weight.
- Pedal Body: Made from a composite material, the pedal body is designed to be lightweight yet strong. The aerodynamic shape helps in reducing drag.
- Axle and Bearings: The axle is made from chromoly steel, known for its strength and resistance to wear. The sealed bearings are designed to keep out dirt and moisture, reducing the need for frequent maintenance.
- Contact Surface: The wide contact surface provides better power transfer. This area is designed to ensure that the foot remains stable, minimizing energy loss during pedaling.
- Cleat Interface: The interface between the pedal and cleat is engineered for secure engagement and smooth release. The adjustable tension allows for customization based on rider preference.
Real-World Application and Feedback
Cyclists who use the Look Keo Blade pedals often report noticeable improvements in engagement and power transfer. The lightweight design and aerodynamic benefits are especially appreciated during competitive races and long rides. Professional cyclists favor these pedals for their reliability and performance consistency.
A pivotal feature of the Look Keo Blade pedals is the integration of carbon blade technology. Diverging from traditional spring mechanisms, the Keo Blade employs a carbon blade for tension. This design provides a secure and consistent engagement and release system, essential for performance cycling. The carbon blade mechanism not only enhances reliability but also reduces the pedal’s overall weight, contributing to a lighter and more aerodynamic profile.
Teardown
Understanding the intricacies of the Look Keo Blade pedals highlights the importance of each component in contributing to the overall performance. For cyclists aiming to optimize their ride, these pedals offer a well-engineered solution that balances innovation with practical application.
Bearing Replacement
Look do use a non standard bearing in their pedals and a Look engineer reached out to the channel after the teardown and stated they were to do with the weight.
The video below shows how to change the bearing on the axle.
