Rim Brakes vs Disc Brakes For Bicycle Touring

Have you ever wondered what the real difference is between disc brakes vs rim brakes, and which one would suit your cycling needs better? 

While disc brakes outperform rim brakes in almost every area, it doesn't necessarily make them the best choice for bike touring. That's because there are other things to consider, such as availability of spare parts, ease of repairs, and frame compatibility.

Personally, I prefer rim brakes for my touring bikes. This is because my experiences of cycling in quite remote areas and developing countries have led me to the conclusion that the simpler a bike and its components are, the easier it is to maintain, repair, and source parts for.

For example, even in the dustiest bike shop in Peru, you can find brake pads for rim brakes, brake shoe assemblies, and the other nuts and bolts needed for those inevitable repairs after a few months of cycling.

Trying to replace or repair disc brake rotors, and disc brake systems in developing countries is an exercise in patience, and often involves having to get items shipped to you which takes time and of course is not cheap either.

That said, for people who cycle solely in parts of the world where there is a well stocked bike shop every 100 miles, disc brakes make total sense and are an obvious choice.

If you're wondering what type of brakes you should have for your touring bike (assuming you even have a choice nowadays!), my advice is to future proof your decision. Where do you plan to ride and bike tour in the future? 

Also, it's a good idea to see if your local bike shop stocks spares of the braking system you decide upon. If they don't, it might not be a good choice when bike touring!

Understanding Disc and Rim Brakes

As a cyclist, you might have come across two main types of braking systems: disc brakes and rim brakes. Disc brakes use calipers that apply force to rotors, while rim brakes use pads that press against the wheel rim.

But how do these systems differ in performance, compatibility, and maintenance? Let's explore the world of disc brakes and rim brakes in more detail.

Disc Brakes

Disc brakes consist of a rotor attached to the hub near the center of the wheel and a caliper that pushes brake pads against the rotor, creating friction to slow down the bike.

Disc brakes are of two types – mechanical and hydraulic. Both have their own advantages and disadvantages. Mechanical disc brakes utilize a cable to transfer force from the brake lever to the caliper, while hydraulic disc brakes use fluid-filled lines to convey the force, resulting in a smoother and more efficient braking experience.

The advantages of disc brakes include more stopping power, better control, and the ability to accommodate wider tires. A good choice for Fat Bike enthusiasts, but also something to consider when bikepacking.

Additionally, they are less affected by rain and water, which reduces the chances of brake pads slipping and ensures consistent performance in various weather conditions. One negative though, is that oil on the brake discs can cause a problem – so be careful when oiling your chain with spray (which I hope you don't, but some people do!).

Finally, disc brakes can be more expensive and require additional maintenance compared to rim brakes.

Rim Brakes

Rim brakes, on the other hand, use pads that press against the wheel rim, slowing down or stopping the bike. There are several types of rim brakes, such as V-brakes, cantilever, and caliper brakes, among others.

Rim brakes are generally lighter and more affordable than disc brakes, making them a popular choice for casual riders.

However, rim brakes have some limitations. They can cause rim wear over time due to the friction between the brake pads and the rim.

Brake Performance Comparison

Now that we've covered the basics of disc and rim brakes, let's dive into a head-to-head comparison of their braking performance.

Disc brakes are known for their consistent and responsive stopping power, better modulation, and improved performance in wet conditions.

But how do they fare against rim brakes when it comes to stopping power, modulation, and weather conditions? Let's find out.

Stopping Power

One of the key factors to consider when comparing braking systems is stopping power. Disc brakes offer more reliable and responsive stopping power than rim brakes.

This is due to the friction created by the caliper pressing the brake pad against the rotor. Hydraulic disc brakes, in particular, require significantly less force on the lever compared to rim brakes, making them more efficient and easier on your muscles during extended braking periods.

Larger disc brake rotors also contribute to increased stopping power, as they provide more surface area for the brake pads to act on. In comparison, rim brakes may not offer the same level of stopping power, especially in wet conditions where the brake pads can slip on the rim.

Modulation

Modulation refers to the ability to control the amount of clamping force on a brake with a given amount of input, allowing the rider to precisely control how much force is applied with each brake input.

Disc brakes offer better modulation than rim brakes, as they provide more powerful braking and less susceptibility to wet or muddy conditions, resulting in improved braking control.

Rim brakes, on the other hand, may not provide the same level of modulation as disc brakes. This can make it more challenging for riders to fine-tune their braking force, which may be especially noticeable in technical riding situations where precise control is crucial.

Weather Conditions

Weather conditions can significantly affect the performance of braking systems. Disc brakes generally perform better in wet weather than rim brakes, as they maintain consistent stopping power and control even when exposed to rain and water.

The design of disc brakes ensures that water and dirt are quickly cleared away from the braking surface, minimizing the impact of adverse conditions on performance.

Rim brakes, however, may suffer in wet conditions, as water can cause the brake pads to slip on the rim, reducing their braking power. This can lead to less predictable performance and potentially risky situations, particularly when riding in challenging terrains or adverse weather conditions.

Bike Compatibility and Setup

Selecting the right brake system for your bike not only depends on performance factors but also on compatibility and setup considerations. Disc brakes require specific fittings on the frame and wheels, while rim brakes have different compatibility requirements.

In this section, we'll discuss the various aspects of bike compatibility and setup for both disc and rim brakes.

Frame Compatibility

When it comes to frame compatibility, disc brakes require specific fittings on the frame and fork for the caliper. The bike frame should ideally be designed for disc brakes to ensure optimal performance and compatibility.

On the other hand, rim brakes usually limit how tall and wide the tires can be, whereas disc brakes, mounted directly to the frame and fork, don't have that issue.

Although it is possible to convert a rim brake-compatible bike frame to use disc brakes by adding a disc brake mount, this may not be the most practical option for all riders.

In general, it is important to ensure that your bike frame can accommodate the brake system you prefer, whether it's disc or rim brakes.

Wheel Compatibility

Wheel compatibility is another crucial factor to consider when choosing between disc and rim brakes. Rim brake wheelsets must have a braking surface to operate correctly. Disc brake wheels however, do not require one. This means that if you're switching from rim brakes to disc brakes, you'll need to invest in new, disc-compatible wheels as well.

In addition, the type of rotor required for wheels with disc brakes is essential to consider. The rotor is the perforated ring that goes around the wheel hub, and it plays a significant role in the braking process. Ensuring that your wheels are compatible with your chosen braking system is vital for optimal performance and safety.

Brake Setup and Maintenance

Setting up and maintaining your brakes is an important aspect of bike ownership. Rim brakes are generally easier to maintain than disc brakes, as they require fewer tools and less expertise.

Simple tasks such as replacing brake pads can be quickly accomplished with minimal effort. Additionally, consumables for rim brakes typically cost less than those for disc brakes and are a lot easier to find no matter where you are in the world.

On the other hand, disc brakes can be more complicated to service and usually require more tools and know-how than rim brakes. For riders who are less mechanically inclined or who prefer a simpler brake system, rim brakes may be a more suitable option.
