Pros and Cons of Having Disc Brakes on a Road Bike

Having disc brakes in your bike can increase its efficiency by a long shot. But, there are some drawbacks as well. We have discussed both the advantages and disadvantages of disc brakes below to let you know if they are worth it. 


Here are the pros of choosing disc brakes.

Multi-terrain Usability

The best thing about disc brakes is that they remain functional on all kinds of terrain. Whether you are riding over paved roads or rocky pathways, they will work just fine. They will work even if you have to ride through muddy unpaved roads after rain. 

Lesser Damage to Tires

Another perk of getting disc brakes is that they do not cause friction on the tires. As there is no extra pressure on the tires, they will not get any wear and tear. This is why it is better to go for disc brakes so that you do not have to worry about getting tire repairs. 


Disc brake pads have a greater surface area than rim brake pads. This allows them to transfer energy at a higher rate, which helps the bike cover more distance on lesser energy expenditure. This also helps in keeping the bike frame safe from unnecessary jolts and damage.  


You need to be aware of the cons of disc brakes as well. Some of these include:


Disc brakes are more complex than rim brakes. This causes difficulty in figuring out their assembly and installation. So, you need to spend some time learning how to deal with them. 

How to Choose Disc Brakes For a Road Bike

Choosing the perfect disc brakes for a road bike needs some contemplation on your part. This is to make sure that your investment is safe and you get what you pay for. Here are some of the aspects that you need to keep in mind before making a purchase. 


The foremost concern regarding disc brakes should be efficiency and performance. The brakes should be able to work on all kinds of terrain that you need to ride on. They should also be sensitive and take less effort to slow down or stop your bike.


The rotor of the disc brakes needs to be of the same size as the wheels of your bike. The diameter and width of a rotor make a huge difference when it comes to working accuracy. 


The size of disc brakes is of significance as well since it affects their installation and working. If the disc brakes are too large, they will not fit into your wheels. On the other hand, there will be delayed braking if you use small-sized ones. 


Disc brakes need to have the highest possible compatibility with your road bike. This is to prevent any unnecessary hassle later on.

Why It Stands Out to Us

These disc brakes stand out to us with the 142 x 12 mm thru-axle, which keeps braking at an optimal level of precision. The size of the thru-axle is just perfect for all moderately-sized bikes.

In addition, they have a geometric construction which makes riding comfortable for bikers. The design needs lesser effort from bikers, so they do not feel any fatigue.

Moreover, the discs have a vibration damping mechanism; thus, there is no damage to the frame. This way, you will not feel any jerks on uneven roads while you are riding on them.

Editor’s Pick:
Giordano Trieste Gravel Bike

Giordano Trieste Gravel Bike, 700c Small, Gray


  • Chromoly steel frame and fork
  • Available in three different sizes
  • Double-wall alloy rim construction
  • 16-speed drivetrain for smooth rides
  • Mechanical disc brakes do not frequent bleeding


  • Calipers are flimsy
  • Cable tightening is hard

What Recent Buyers Report

Users are quite fond of these disc brakes because of their steel construction. Both the fork and frame are made of Chromoly steel that stays safe from most damage-inducing elements. Buyers also found it useful in terms of size. They could easily choose the disc brakes that work for the height and the size of their bike.

Why It Stands Out to Us

We think that this product has distinguished itself from us with the Chromoly steel material used in its basic frame and major components. The double-wall rim has alloy material, which is sure to give many years of hassle-free usage.

Furthermore, there are 16-speed drivetrains in the disc brake system. They bring more diversity to the range of speeds and riding experiences that you will have.

Also, as these disc brakes have mechanical discs, they do not involve any fluid dynamics. Hence, they do not need any bleeding or other arduous tasks.

Bottom Line

In our opinion, these disc brakes are well-priced and have amazing qualities as well. The availability of different sizes helps many people choose the right set for themselves. So, if you want to keep your performance high, these disc brakes can be your best bid.

Comparison Overview

There are several kinds of brakes on the market for road bikes. Each of them serves the purpose of slowing down or stopping your bike. Here is a quick comparison of some of the most commonly used types. 

Disc Brakes vs. Rim Brakes For a Road Bike

Here is what makes disc and rim brakes similar to each other and what distinguishes them. 


Let’s first go through the most prominent similarity:


Both rim and disc brakes are quite sensitive. They just need a little force from riders to work and make the bike stop. They also work effectively for both new and old models of road bikes. 


Meanwhile, the differences between the two include:


The major difference between disc and rim brakes is the construction material. Rim brakes use aluminum while disc brakes use different alloy materials. 

Ease of Adjustment

Another difference between disc and rim brakes is the ease of adjustment. The former is easy to install and adjust while the latter needs some particular techniques.

Hydraulic vs. Mechanical Disc Brakes For Road Bike

Both hydraulic and mechanical disc brakes are used in road bikes, but of them have their differences and similarities. Let’s have a look.


Among the similarities, the most obvious one is:

Active Tension

Both hydraulic and mechanical disc brakes use the mechanism of activated tension. This helps them make sure that there is lesser exertion of force from the rider. 


On the other hand, one prominent difference between the two is:


The major difference in these two is that there is fluid in hydraulic disc brakes. Mechanical disc brakes do not use any fluids to push the caliper towards the rotor.

Disc Brakes vs. Conventional Brakes For Road Bike

While most people now opt for disc brakes, some of them are partial to conventional brakes. Let’s see how these two compare to each other. 


One similarity between the two is:


Both disc and conventional brakes serve the same purpose. They stop the bike when any obstacle comes in the way. They also help in controlling the speed of the bike more actively. 


A prominent difference is:


The major difference is that disc brakes have a circular appearance while conventional brakes do not. The latter rubs on the surface of the tire, making them undergo more wear than the former. 

How to Install Disc Brakes on a Road Bike

The working of disc brakes largely depends on how well you install them on your road bike. So, here is the complete procedure of installation to help you get the maximum performance:

  1. First of all, remove the screws on the center of the wheel.

  2. Then place the disc on the center, making sure the holes for screws are in line with the holes in the disc.

  3. Now, screw back all the bolts in their previous place with the disc over the central region.

  4. After this, fix and tighten the caliper line on the fork of your bike.

  5. Lastly, put the wheel back in its place on the road bike and connect the braking wires.

Here is a video demonstration of the installation to help you further. 


To sum it all up, disc brakes are a far better option than conventional rim brakes. They not only help in protecting your bike’s tires but also keep braking accurate. So, go through our list of the best disc brakes and buy one that suits your needs.
