Are Internally Geared Hubs Better? Let's Find Out

The debate over whether internally geared hubs are superior to traditional derailleur systems has been ongoing.

As cycling technology continues to advance, the internally geared hub has emerged as a strong contender, offering numerous advantages that cater to various types of cyclists.

In this article, we will delve into the specifics of internally geared hubs, exploring their benefits, drawbacks, and why they might be the better choice for you.

What is Internally Geared Hub

An internally geared hub is a type of electric bike transmission that houses its gears inside the rear hub, unlike the traditional derailleur system, which relies on an external chain and sprocket setup.

The internal gear system is enclosed within the hub shell, protected from the elements, and operates with a different mechanism compared to the exposed gears of a derailleur.

Advantages of Internally Geared Hubs

1. Low Maintenance and Durability

One of the most significant advantages of internally geared hubs is their low maintenance requirements.

The gears are sealed inside the hub, protecting them from dirt, grime, and moisture.

This design reduces the need for frequent cleaning and lubrication, which is often necessary with external derailleur systems.

As a result, internally geared hubs are highly durable, capable of withstanding harsh weather conditions and rough terrain without compromising performance.

2. Enhanced Reliability

Internally geared hubs offer exceptional reliability due to their enclosed design.

The risk of damage from external factors, such as impacts or debris, is minimized, making them an ideal choice for commuters, touring cyclists, and those who frequently ride in adverse conditions.

Additionally, since the chain remains in a straight line regardless of the gear selected, there is less wear and tear on the chain, further enhancing the system's longevity.

3. Smooth and Predictable Shifting

The shifting mechanism of internally geared hubs is often smoother and more predictable than that of derailleur systems.

Because the gears are shifted internally, there is no need for precise alignment of the chain, which can lead to mis-shifts or chain drops in derailleur systems.

This makes internally geared hubs particularly beneficial for novice cyclists or those who prioritize ease of use over high-performance gear shifting.

4. Clean and Elegant Aesthetics

Internally geared hubs contribute to a cleaner and more elegant bicycle aesthetic.

With no external derailleurs, cables, or exposed gears, bicycles equipped with internally geared hubs have a streamlined appearance.

This not only adds to the visual appeal but also reduces the risk of snagging clothing or other items on the drivetrain components.

5. Ability to Shift While Stationary

A unique feature of internally geared hubs is the ability to shift gears while stationary.

This is particularly advantageous in urban environments where frequent stops are necessary, such as at traffic lights or stop signs.

Cyclists can easily shift to a lower gear before starting again, making it easier to accelerate from a stop and reducing strain on the drivetrain.

6. Longevity and Cost-Effectiveness

Although the initial cost of an internally geared hub may be higher than a traditional derailleur system, the long-term cost-effectiveness is often superior.

The reduced need for maintenance, coupled with the durability of the hub, means fewer repairs and replacements over time.

For cyclists who value longevity and low total cost of ownership, internally geared hubs are a wise investment.

Drawbacks of Internally Geared Hubs

While internally geared hubs offer many advantages, they are not without their drawbacks.

It is important to consider these potential downsides when deciding whether an internally geared hub is the right choice for your cycling needs.

1. Limited Gear Range

One of the primary criticisms of internally geared hubs is their limited gear range compared to derailleur systems.

While advancements have been made in expanding the range of internal hubs, they still generally offer fewer gears than traditional systems.

This can be a disadvantage for cyclists who require a wide range of gears for varied terrain, such as those who engage in mountain biking or long-distance touring.

2. Increased Weight

Internally geared hubs tend to be heavier than derailleur systems due to the additional components housed within the hub.

For weight-conscious cyclists, particularly those involved in competitive cycling, the added weight may be a concern.

However, for most recreational riders, the benefits of reliability and low maintenance often outweigh the slight increase in weight.

3. Higher Initial Cost

As mentioned earlier, the initial cost of an internally geared hub is typically higher than that of a derailleur system.

This can be a barrier for some cyclists, especially those on a tight budget.

It is important to consider the long-term savings in maintenance and repairs when evaluating the overall cost-effectiveness of internally geared hubs.

4. Specialized Repair and Service

Because internally geared hubs are more complex than traditional derailleur systems, they may require specialized tools and knowledge for repairs and servicing.

Not all bike shops are equipped to handle these hubs, and repairs may be more costly if issues arise.

The need for such repairs is generally infrequent due to the hub's durability and reliability.

Who Should Choose Internally Geared Hubs

Internally geared hubs are an excellent choice for a variety of cyclists, but they are particularly well-suited for:

  • Urban Commuters: The ability to shift while stationary, combined with low maintenance and reliability, makes internally geared hubs ideal for city cycling.

  • Touring Cyclists: The durability and low maintenance of internally geared hubs are perfect for long-distance tours where access to bike shops may be limited.

  • Recreational Riders: Cyclists who prioritize ease of use, low maintenance, and clean aesthetics will appreciate the benefits of an internally geared hub.

  • Year-Round Cyclists: For those who ride in all weather conditions, the sealed design of internally geared hubs offers protection from the elements, ensuring consistent performance.

Conclusion

Internally geared hubs offer a compelling alternative to traditional derailleur systems, especially for cyclists who value low maintenance, reliability, and ease of use.

While they may come with some drawbacks, such as limited gear range and higher initial cost, the benefits often outweigh these disadvantages for many riders.

Whether you're an urban commuter, touring cyclist, or someone who enjoys leisurely rides, an internally geared hub could be the right choice to enhance your cycling experience.

FAQs

How do internally geared hubs perform in extremely cold weather?

Internally geared hubs generally perform well in cold weather due to their sealed design, which protects the gears from snow, ice, and moisture. However, extreme cold can sometimes affect the hub's lubrication, leading to stiffer shifting. It's recommended to use cold-weather-specific lubricants for optimal performance.

Are there any e-bikes that come with internally geared hubs?

Yes, many e-bikes come equipped with internally geared hubs, particularly those designed for urban commuting and casual riding. The integration of an internally geared hub with an electric motor provides a smooth and low-maintenance riding experience.

How does the noise level of an internally geared hub compare to a derailleur system?

Internally geared hubs are generally quieter than derailleur systems, especially when shifting. The internal mechanism is designed to reduce noise, making them a good choice for cyclists who prefer a quieter ride.
