10 Best Mountain Bike Hubs in 2021 – Reviews & Top Picks

There are enough mountain bike reviews to fill up several encyclopedias and still leave enough details out.

Simply put, these bicycles have revolutionized mountain biking. They can be correctly described as the apex of cycling technology, as their ability to deal with tricky terrains like mountains and hillsides is something worth marveling at.

Among their many parts, one of the most intriguing is the hubs found on their wheels. What are they exactly?

In a nutshell, without a rear hub, you won’t be going anywhere.

Mountain bike hubs come in various types, and we’re going to look at the best ones on the market that are suited for the mountain bike.

What to Consider When Buying Rear Hubs?

Choosing the right hub for your mountain bike wheels can be challenging, whether you’re an experienced mountain biker or not. The sheer numbers of hubs brands that proclaim the best efficiency can leave you confused, so to help you make an informed decision, here’s a buying guide you can use.


Mountain bikes are generally heavy. They’re equipped with a lot of accessories that are necessary for their operations, given how rough the terrain they’ve been designed for can be.

Therefore, any chance of cutting down that weight should be embraced wholly.

The weight of the wheel hub directly affects the bike’s unsprung mass, which ultimately impacts the performance. The smaller the hub, the better the handling, navigation, and ride quality.

Strength and Durability

You want a wheel hub that will last you years since they never come cheap.

Since they’re positioned in places that involve a lot of movement, they’ll be affected by the wear and tear. However, how fast that happens is what should be of concern to you.

Get MTB hubs that are made using strong materials that can last for a while before the need for change arises.

Bearing Type

Bearings for tires come in two types depending on their covering. You can either go for Cartridge type or the Cup and Cone type.

Each comes at a different budget; the bottom line here, however, is that you ought to go for bearings that are of good quality, that are sealed securely and shielded from the elements, and the type that’s easy to service on your own.

Cup and cone bearings are cheaper but are a bit hard to fine-tune to what you need. Cartridge bearings are more convenient, but they cost more, and replacing them is also costly.

Bike Compatibility

Not just any type of mountain bike hub can go into any set of wheels; there are compatibility issues that have to consider first.

The tires hub has to be compatible with the mountain bikes. You have to look at the axle size, the frame design, and the number of spokes on the rim, and make sure they match up with the number of holes on the hub.

The same applies to the brake rotor; disc brake systems need corresponding MTB hubs for them to attach correctly. Brake rotors can either be Six-Bolt or Centerlock.

Check the braking system on your bike first to avoid the mistake of getting the wrong fit.


Most wheel hubs are made using some form of aluminum because aluminum is strong and light. There’s an option for hubs made of carbon fibre, but they’re priced so high that not many bicycle wheels even consider them in their designs.

On the other hand, steel is stronger and durable, but it’s avoided for the sheer fact that it weighs a lot more, and this will affect efficiency. Maybe in the future, more wheels will embrace carbon fiber hubs.

Engagement Points

Engagement points refer to the number of ‘clicks’ you hear when your rear wheel hubs are moving. It’s the number of times the internal machinery spins to complete one revolution.

The basic principle here is that the more engagement points, the more beneficial the hubs. You get a smoother ride on a higher number of freehub body engagement points compared to a lowly one.

The Bottom Line

No type of bike tires can move without hubs, and it’s for this reason that bike manufacturers are investing a lot in developing their own unique devices. When looking for the best mountain bike wheelset hubs, pay attention to the brand, the weight, and the number of engagement points.

Each of the hubs mentioned above works in its own way. Whether one is superior to the other doesn’t matter much; how you apply them is more important.

Therefore, if you’re a fan of mountain riding and have been putting off buying hubs for your MTB, then this guide should give you the reviews you need to get that done finally.
