With so many brake systems available for bicycles, it is difficult to figure out which type would be most suitable for your bike and riding style. The two most commonly used are Rim Brakes and Disc Brakes and understanding the difference between these two systems is crucial to making the right choice.

Rim Brakes

Practically and Aesthetically

Rim brakes consist of two pads that clamp onto the wheel rim to stop the bike, making them the most lightweight and most cost-efficient of the two braking systems. Most rim brakes are easy to set up and maintain, making them a popular choice for entry-level bicycles. In terms of aesthetics, rim brakes often add a classical look to a bike but, as with all brakes, their performance in wet weather conditions can be significantly lower.


Rim brakes have to be made of metal and some riders may find this uncomfortable for longer rides. Furthermore, applying too much pressure to the rim can cause the wheels to deform or buckle. Rim brakes are usually limited to a single speed, making them less suited to more rugged conditions such as mountain biking.

Disc Brakes

Installation and Performance

Disc brakes are mounted on either the hub or center of the wheel. They are generally more complex and expensive than rim brakes and require more specialised tools to install. However, they are also more efficient at dissipating braking force and can generate more power and stopping ability than rim brakes. Disc brakes are not affected by dirt and mud, something which can cause rim brakes to fail.

Disc brakes can be used with multiple gears and are the preferred choice for mountain biking and bicycle touring due to the higher power and better performance in wet conditions. Disc brakes can also be adapted to almost any wheel size and shape and can be made lighter than rim brakes.

People Also Ask

What are the Pros and Cons of Disc Brakes?

The main advantages of disc brakes are their higher stopping power, better performance in wet conditions and compatibility with multiple gears. The drawbacks include the complexity of installation, higher cost, and potential for disc warping or rubbing if not set up correctly.

Are Disc Brakes Easier to Maintain than Rim Brakes?

Although discs generally require more time and specialist tools to install, the maintenance for the two systems can be relatively equal. Disc brakes require the periodic adjustment of the caliper alignment, the pad replacement and regular cleaning. With rim brakes, the pads still need to be replaced periodically but the cable and housing may require more frequent attention.

Do Disc Brakes Require More Power?

The short answer is yes. Disc brakes require more power than rim brakes as the rider must press into the brake lever harder than they would with a rim brake. This is due to the thicker brake pads and the increased friction they create on the rotor.

Are Disc Brakes Stronger than Rim Brakes?

Disc brakes tend to be stronger than rim brakes due to their ability to dissipate more heat and their ability to generate more power and stopping ability than a rim brake. However, they also require more power to activate, so this may be a consideration when choosing between the two braking systems.

Final Words

It is clear that the differences between rim brakes and disc brakes can be significant, no matter the bike or style of riding. To decide which one is more suitable for your bike and riding style, take into consideration the cost, braking power, style, and ease of use. Disc brakes are generally considered more powerful and reliable in extreme weather conditions, whereas rim brakes are typically lighter, more cost-effective, aesthetically pleasing, and easier to set up and maintain.
