Understanding Bicycle Hubs Before Customizing

Table of Contents


Bicycle hubs are an imperative component of bicycles, and therefore, in manufacturing and producing them, it is of importance that you work with a premier manufacturer of custom bicycle hubs – like with us here at HDC Manufacturing.

Before we dive deeper into that, let us first enlighten you with some of the most important information you ought to know before choosing custom bicycle hubs for your products.

Understanding Bicycle Hubs

Bicycle hubs are considered as one of the most important parts or components of a bicycle, as it acts as the center or middle part of the wheels of your bicycle. The main purpose of these hubs is to be a type of anchor point for the spokes, as well as to be a holder of the bearings in place for both the front and rear wheels to spin.

You’ll be able to find many different types and kinds of bicycle hubs in the market, but not all of them are created equally.

Types of Mountain Bike Hubs

There are quite a few different types and classifications of bicycle hubs you’ll find in the market. To help you with it, let us list down the four (4) types of hubs you can get:

Track Hub

Track hubs are distinctive because of their stepped threads. The mean thread is the one that wheels sprockets or spokes.

Flip Flop Hub

Also commonly known as flip flop hubs, these bicycle hubs are threaded on both sides, where one side is built with track type threading while the other is built with a single-speed freewheel.

Freewheel Hub

These are the most conventional type of hub where you commonly see in almost all different types of bicycles.

Cassette Hub

Lastly, these types of hubs are designed to be utilized along with disc wheels. Out of all the different types of bicycle hubs, these are the most expensive ones. The only reason why they’re used in situations where they are extremely effective on the road.

Difference Between Front and Rear Bicycle Wheel Hubs

Front and rear bicycle wheel hubs are distinct in their functions and designs, tailored to their specific roles on the bike. The front hub, with its simpler construction, is narrower and more streamlined, designed to facilitate smooth wheel rotation. It lacks the additional mechanisms of the rear hub, which is more complex and robust to transfer pedaling power through the drivetrain. This complexity is evident in the rear hub’s wider and bulkier appearance, necessary to accommodate drivetrain components like the freehub body and cassette or freewheel, making it noticeably larger in diameter and with more pronounced flanges.

Moreover, the rear hub is built to withstand the torsional forces of pedaling, often necessitating a higher spoke count or stronger spoke patterns compared to the front hub, which further adds to its bulkier look. The engineering of these hubs also reflects in their axle dimensions and hub spacing; rear hubs are broader to align with the bike’s rear dropout spacing and to support the drivetrain’s load. Although both hubs can be adapted to various braking systems, their physical configurations and the way they integrate with rim or disc brakes differ, influenced by their structural and functional requirements. These design distinctions between front and rear hubs are crucial for ensuring the bicycle’s optimal performance and rider safety.Custom Bicycle Hubs Manufacturer

Are Bicycle Wheel Hubs Usually Sold in Pairs, Front, and Rear?

Bicycle wheel hubs are not typically sold in pairs that include both front and rear hubs. They are usually sold separately to allow cyclists to choose each hub according to their specific needs, such as compatibility with the drivetrain, braking system, and wheel size. This customization is important because the front and rear hubs have different requirements and specifications, such as width, bearing types, and attachment methods for the drivetrain components.

However, it is possible to find hub sets designed to work together, especially from high-end manufacturers or for specific types of bicycles, like road, mountain, or gravel bikes. These sets are designed to ensure compatibility and performance across the front and rear wheels. But generally, in the bicycle market, hubs are often chosen and purchased individually to meet the particular specifications and performance requirements of the front and rear wheels of a bike.

What Hubs Do Pro Cyclists Use?

Pro cyclists make use of distinctive green hubs, also known as the Chris King R45s. These are lightweight bicycle hubs that are with 45 teeth for fast and urgent engagement.

Importance of Bicycle Hubs

When it comes to the importance and relevance of bicycle hubs, they’re not necessarily “required” per se for bicycles. It is actually a component that’s primarily utilized to improve and develop the performance of bicycles.

CNC bicycle hubs, furthermore, are exceptionally significant components in reinforcing the performance of the bicycle that are used for professional purposes.

Choose the Right Bike Hubs

Choosing the correct bicycle hubs for your products can be challenging and complex at the same time, due to the fact that incorrectly-sized hubs can negatively impact not only the performance of the bicycle, but also the safety of the rider.

There are a few things to take into account when selecting your bicycle hubs. These include:

Bearing Type

Bearings should almost always be sealed, protected from water and dirt, as well as be flexible. You’ll find a few types of bearings for bicycle hubs, but the most important and most notable ones would be cup and cone bearings.

Material Used

The majority of bicycle hub manufacturers use lightweight aluminum alloy or stainless steel for their products. However, there are suppliers that are slowly leaning towards carbon fiber bicycle hub units, which are intended for higher and better-quality performance of the bicycle.

Axle Type

The fork axle of your bicycle needs to be compatible with both the front and rear bicycle hubs, therefore, the size and the form must be in place according to the axles.


Last but most definitely not least is the fact that you need to consider the rims. These rims must match both the type and the number of spoke holes on the flange of the hub to the spoke that has been drilled onto them.

These are some of the considerations you want to factor in when you are choosing your bicycle hubs.

Materials Used to Manufacture Custom Bicycle Hubs

There are actually a few categories manufacturers use in creating and producing custom bicycle hubs.

There is what we call cheap hubs, and these are made of three (3) pieces of steel, two (2) for the spokes and one (1) tube in between. The middle-range hubs are usually made from aluminum hubs for the middle and steel on the sides, and the most expensive one would be by using aluminum all the way through.

Nevertheless, the most common materials used for the manufacturing of custom bicycle hubs would be steel (could be carbon steel or stainless steel) and aluminum.
