What I asked ChatGPT
“Write an article on mountain bike hubs”

ChatGPT’s response
“Mountain biking is a thrilling outdoor activity that requires a lot of preparation and maintenance. Among the various components of a mountain bike, the hubs are perhaps one of the most critical elements. They connect the wheels to the bike frame and play a vital role in ensuring smooth, efficient, and safe riding. In this article, we’ll take a closer look at mountain bike hubs, their types, and how to choose the right one for your riding style.

What are Mountain Bike Hubs?

Mountain bike hubs are the central part of the bike’s wheel assembly. They are located at the center of the wheel and connect the spokes to the axle. Sorta accurate but would have been better to say rim not axle Hubs are responsible for enabling the wheel to rotate on the axle, thus providing the rider with the ability to pedal, steer, and brake. They also help to absorb shock and maintain stability on rough terrain.  I wouldn’t say hubs do much to  absorb shock or maintain stability but you could probably argue the point if looking at mostly insigificant amounts of difference.

Types of Mountain Bike Hubs

There are two types of mountain bike hubs: front hubs and rear hubs. Front hubs are located at the front wheel of the bike, while rear hubs are located at the rear wheel. Rear hubs are larger and more complex than front hubs, as they must accommodate the cassette that contains the bike’s gears.

Mountain bike hubs can also be classified by the number of spoke holes they have. The most common number of spoke holes for mountain bike hubs is 32, but hubs can have as few as 24 holes or as many as 36 holes. The number of spoke holes determines the strength and durability of the wheel.  This is surprisingly accurate, there are naturally more spoke counts available but those are rare enough that I think this is a valid response given the context.

Finally, mountain bike hubs can be classified by their engagement mechanism. The engagement mechanism is the part of the hub that allows the rider to apply power to the wheel. There are two types of engagement mechanisms: pawl and freehub.  This is definitely a bit off, the freehub typically is just the holder for the pawls with a number of actual drive types available.

Pawl Hubs

Pawl hubs are the most common type of engagement mechanism found on mountain bike hubs. They are simple and reliable, and they work by using pawls (small metal teeth) to lock the wheel to the hub when the rider applies power to the pedals. Pawl hubs are also easy to service and maintain.

Freehub Hubs

Freehub hubs are a newer type of engagement mechanism that is becoming more common on mountain bikes. They work by using a ratcheting system to lock the wheel to the hub when the rider applies power to the pedals. Freehub hubs offer faster engagement and better power transfer than pawl hubs, but they are also more complex and difficult to service.  Again, freehubs are just the part that holds the pawls on most hubs and lets you attach your cassette to the hub.

How to Choose the Right Mountain Bike Hub

When choosing a mountain bike hub, there are several factors to consider, including:

Riding Style: Different riding styles require different types of hubs. For example, if you’re a cross-country rider, you’ll want a lightweight hub that offers fast engagement. If you’re a downhill rider, you’ll want a hub that is strong and durable and can handle the rigors of rough terrain.  Accurate but light hubs can also still be strong, they usually are just not cheap.

Budget: Mountain bike hubs can range in price from less than $100 to over $500. It’s important to choose a hub that fits your budget, but also meets your performance needs.

Compatibility: Make sure the hub you choose is compatible with your bike frame and other components, such as the cassette.

Engagement Mechanism: Consider whether you want a pawl or freehub engagement mechanism, and choose the one that best meets your needs.  See above notes…


Mountain bike hubs are an essential component of any mountain bike. They connect the wheels to the bike frame and play a crucial role in ensuring smooth, efficient, and safe riding. When choosing a mountain bike hub, consider your riding style, budget, compatibility, and engagement mechanism. With the right hub, you can enjoy a more comfortable, confident, and exhilarating ride on the trails.”

Overall I am actually pretty impressed by their response on this first question even if its not a perfect response yet.  Mountain bike hubs are a pretty niche topic to cover so well for an AI platform that is still in beta testing.

Our follow up question

“What are the best mountain bike hub brands”

Chat GPT’s response
“There are many high-quality mountain bike hub brands on the market, each offering unique features and benefits. Here are some of the best mountain bike hub brands to consider:  Truth, most mid-high end hubs all work quite well.

Chris King: Chris King is a well-known brand that is synonymous with high-quality, precision-made hubs. Their hubs are known for their durability, smoothness, and ease of maintenance.  I wouldn’t give them ease of maintenance but the rest fits.

Industry Nine: Industry Nine is a brand that prides itself on producing lightweight, high-performance hubs with fast engagement. Their hubs are made in the USA and are known for their unique and colorful designs.  Spot on

DT Swiss: DT Swiss is a Swiss brand that is known for its precision engineering and attention to detail. Their hubs are reliable, durable, and versatile, making them a popular choice among mountain bikers of all skill levels.  Nailed it

Hope: Hope is a UK-based brand that has been producing high-quality mountain bike components for over 30 years. Their hubs are known for their reliability, ease of maintenance, and attractive designs.  Still spot on

Shimano: Shimano is a Japanese brand that produces a wide range of cycling components, including mountain bike hubs. Their hubs are known for their durability, smoothness, and compatibility with other Shimano components.  Pretty spot on although not every variant of their hubs is durable but most work well for a number of riders.

Ultimately, the best mountain bike hub brand for you will depend on your specific needs and preferences. It’s important to do your research, read reviews, and consider factors such as weight, engagement mechanism, and compatibility when choosing a hub.”

I really think this second question was answered even better than the first.  It probably helped that my second question was a bit more specific but I was curious to see how it would take such a broad question.
