Mountain Bike Wheels: Different wheel sizes and materials, and their benefits and drawbacks

Mountain Bike Wheels

Mountain bikes come with a variety of wheel sizes and materials, each with its own set of benefits and drawbacks. Here’s a rundown of some common options:

  • Wheel size: Mountain bikes are available with 26-inch, 27.5-inch (also known as 650b), and 29-inch wheels. Larger wheels tend to roll over obstacles more easily and offer a smoother ride, but they can also be slower to accelerate and may not be as agile as smaller wheels. Smaller wheels offer quicker acceleration and a more responsive ride, but they can also be more prone to getting stuck on larger obstacles.

  • Material: Mountain bike wheels are typically made from either aluminum alloy or carbon fiber. Aluminum alloy wheels are generally less expensive and more durable, but they are also heavier than carbon fiber wheels. Carbon fiber wheels are lighter and can offer a more responsive ride, but they are also more expensive and may be less durable.


  • Rim width: Mountain bike rims are available in a range of widths, from narrow to wide. Wider rims can offer improved traction and stability, especially when used with wider tires, but they may also be heavier and more expensive. Narrower rims are lighter and more cost-effective, but they may not offer as much traction and stability.

Ultimately, the best wheel size and material for your mountain bike will depend on your personal preferences and the type of riding you do. It’s worth considering all of these factors when choosing wheels for your mountain bike.

Mountain Bike Wheels With Disc Brakes

Mountain bikes with disc brakes are becoming increasingly popular, and for good reason. Disc brakes offer a number of benefits over traditional rim brakes, including improved braking performance in wet and muddy conditions and greater durability. Here are a few things to consider when choosing mountain bike wheels with disc brakes:

  • Compatibility: Make sure the wheels you choose are compatible with your bike’s disc brakes. Some mountain bikes use a specific type of disc brake mount, such as post mount or flat mount, so you’ll need to choose wheels that are compatible with your bike’s specific mount type.


    Hubs: Look for wheels with disc brake-specific hubs, which are designed to accommodate the rotors and mounting bolts for disc brakes. These hubs are typically stronger and more durable than those designed for rim brakes.


    Axle type: Consider the type of axle your bike uses, as this will determine which wheels you can use. Mountain bikes can have quick-release axles or thru-axles, and you’ll need to choose wheels that are compatible with your bike’s axle type.


    Rotor size: Mountain bike disc brakes are available in a range of rotor sizes, from small to large. Larger rotors offer improved braking performance, but they can also be heavier and more expensive. Choose a rotor size that is appropriate for your bike and your riding style.
