7. Nickel steel: Nickel steel axles are used for their superior toughness and wear resistance, with a tensile strength of about 1,000 MPa, but they are heavier and more expensive than other steels.

Why do bike wheels have axles?

Bike wheels have axles because they serve as the central pivot around which the wheels rotate, providing the necessary support and alignment for smooth, efficient movement. The axle transfers the load from the bike frame to the wheels, maintaining the structural integrity of the bicycle and allowing for the conversion of rider-generated force into forward motion. By ensuring the wheels rotate around a fixed axis, the axle also helps maintain balance, stability, and control, crucial for effective steering and overall bicycle performance.

Bike axle types

Bike axles come in a variety of types to meet the diverse needs of different bicycle designs and riding conditions. They are categorized based on structure, such as Quick Release, Through Axle (Thru-axle), and Quicker Thru-axle; based on axle body, like Hollow or Solid; based on position, with Front or Rear axles; and based on bike types, including Road, Mountain, Gravel, Fat, and Indoor Bike Trainer axles. These distinctions ensure the axle’s strength, ease of use, and compatibility with specific bikes and riding scenarios.

Bike axle type based on structure

Bike axle types based on structure are categorized into Quick Release, Through Axle (Thru-axle), and Quicker Thru-axle, sorted by their mechanisms of securing the wheel to the bike frame, with each type designed to balance ease of use, strength, and stability for different riding conditions and bike designs.

Quick release bike axle

The Quick Release (QR) bike axle is a popular and widely used mechanism that allows for fast and tool-free removal and installation of bike wheels. It consists of a skewer, lever, and nut, which tighten the axle through the hub and secure the wheel to the bike frame. The quick-release lever, when flipped open, loosens the axle, allowing the wheel to be easily removed. This system is commonly found on road bikes, commuter bikes, and older mountain bikes because it offers convenience and speed when changing wheels. However, the trade-off for this convenience is that QR axles are generally less stiff and secure compared to thru-axles, which can lead to less precise handling, especially under heavy loads or in rough terrain.

Through Axle (Thru-axle)

The Through Axle, or Thru-axle, is a more robust and secure type of bike axle commonly used in modern mountain bikes, gravel bikes, and higher-end road bikes. Unlike the quick-release axle, the thru-axle is a solid or hollow shaft that threads directly into the bike frame or fork, passing through the hub to provide a more rigid connection. This design minimizes flex, improves wheel alignment, and increases overall bike stiffness, which enhances performance, particularly in rough or technical terrain. The increased security and stiffness of thru-axles make them ideal for bikes with disc brakes, where precise wheel alignment is crucial for proper braking performance. The trade-off is that thru-axles require a tool (usually a hex wrench) for wheel removal, which can be less convenient than quick-release axles.

Quicker thru-axle

The Quicker Thru-Axle is an evolution of the standard thru-axle, designed to combine the stiffness and security of a thru-axle with the ease of use of a quick-release system. This type of axle often features a built-in lever or quick-release mechanism that allows for tool-free removal and installation, similar to traditional quick-release axles. Quicker thru-axles are used in high-performance road and mountain bikes where both ease of maintenance and robust performance are desired. They are particularly favored in competitive cycling, where quick wheel changes are essential without sacrificing the benefits of a thru-axle’s stability and precision.

Bike quick release vs thru axle

Quick release (QR) and thru-axle are two common types of bike axles, each with its own strengths and use cases. Quick release axles are known for their convenience and ease of use, allowing for fast wheel changes without tools, making them ideal for road bikes and older mountain bikes. Thru-axles, on the other hand, offer greater stiffness and security, providing better performance in demanding conditions, which makes them a preferred choice for modern mountain bikes, gravel bikes, and high-end road bikes, especially those equipped with disc brakes. Here’s a comparison of these two axle types below.

Bike axle type based on axle body

Bike axle types based on the axle body are categorized into Hollow and Solid axles, which are differentiated based on their internal structure. Hollow axles are typically lighter and allow for better weight distribution, often used in performance-oriented bikes like road and mountain bikes, where reducing weight is crucial. Solid axles, on the other hand, offer greater strength and durability, making them suitable for bikes that require higher load-bearing capacity, such as BMX bikes and some heavy-duty commuter bikes. These categories are sorted based on the axle’s internal structure, which directly influences the bike’s overall performance and suitability for specific riding conditions.

Hollow axle

Hollow axles are designed with a void running through their center, which reduces the overall weight without significantly compromising strength. This design is particularly beneficial for road bikes, mountain bikes, and other performance-oriented bicycles where weight savings are critical. The hollow structure allows for better weight distribution, enhancing the bike’s handling and agility. Additionally, the reduced weight can contribute to quicker acceleration and improved efficiency during climbs. Hollow axles are typically made from materials like aluminum or titanium, which provide a good balance between weight and strength, making them ideal for competitive and recreational riders who prioritize speed and responsiveness.

Solid axle

Solid axles, as the name suggests, are entirely solid with no internal void, making them inherently stronger and more robust than hollow axles. This increased strength makes solid axles suitable for bikes that require higher strength and durability, such as BMX bikes, fat bikes, or utility bicycles that carry heavy loads. Solid axles are less prone to bending or breaking under extreme stress, which is why they are often used in bikes designed for rough terrain or heavy-duty applications. However, the trade-off is that solid axles are heavier than hollow axles, which can affect the bike’s overall weight and handling. Typically, solid axles are made from materials like steel or chromoly, providing the necessary toughness to withstand harsh riding conditions and heavy impacts.

Bike axle type based on front or rear

Bike axles are categorized as front or rear based on their position and function in the bicycle; the front bike axle is typically shorter and designed to fit the front wheel, providing stability and steering control, while the rear bike axle is longer and sturdier to accommodate the drivetrain components like the cassette and derailleur, offering the necessary support for pedaling forces and maintaining rear-wheel alignment.

Front bike axle

A front bike axle is a crucial component that secures the front wheel to the bike’s fork, typically found in both quick-release and thru-axle systems. The front axle is shorter than the rear axle and is designed to handle the steering forces and vertical loads experienced during riding. In road bikes, a lighter quick-release axle might be used for its ease of wheel removal, while in mountain and gravel bikes, a thru-axle provides greater stiffness and stability, ensuring precise handling and better control over rough terrain. The front axle’s primary function is to keep the wheel securely in place while allowing for quick and easy maintenance when needed.

Rear bike axle

The rear bike axle is generally longer and more robust than the front axle, as it must support the bike’s drivetrain components, such as the cassette, derailleur, and chain. It is responsible for transmitting the rider’s pedaling power to the rear wheel, making it a critical part of the bicycle’s performance. On road bikes, a quick-release axle may be used for convenience in wheel changes, but for mountain and gravel bikes, a thru-axle is preferred for its added strength and rigidity, which are essential for handling the stresses of off-road riding. The rear axle must ensure the wheel remains perfectly aligned with the frame and drivetrain, allowing for smooth and efficient power transfer.

Bike axle type based on bike types

Bike axles are categorized based on the specific requirements of different bike types—road, mountain, gravel, fat bikes, and indoor bike trainers—because each bike type demands different levels of strength, stiffness, and compatibility with the bike’s frame and components. These differences are driven by the terrain, intended use, and the load the axle must bear.

1. Road Bike Axles: Typically lighter and designed for speed and efficiency on paved surfaces. Quick-release axles are common, though thru-axles are becoming more popular for added stiffness.
