Road bikes are bicycles made for riding on paved areas as quickly and as far as your legs can carry you. The name “road bike” refers to the surface on which it is intended to be used: the road. Road bikes also have a reputation for being loud. So, what makes road bikes so loud?
The majority of road bikes use carbon rims. These are expensive, but they make riding a road bike significantly louder. Apart from that, most road bikes also use a higher-end freehub, which is known to be noisy due to the working of the pawls. Lastly, road bikes also use higher-end cassettes, which are also known for their loudness.
Before we examine these reasons more deeply, let’s look into what a road bike is.
What is a Road Bike?
Road bikes have a long history of being used in competition. With lightweight structures and slick, thin tires that allow you to easily tear through paved areas, they are designed for speed. They have become so popular for their speed that disc-brake versions have just started to appear. They are still mostly used by casual riders.
Anyone looking to rack up miles, travel large distances, or participate in group riding sessions where everybody helps each other out would do well on a road bike. It will contribute to making your journey safer and more enjoyable, though, if you are familiar with their high price, the potential for flat tires, and other annoying cars on the road.
The road bike doesn’t appear to have undergone much modification over time since its first appearance. It’s a conventional bicycle with a nearly identical profile to those that raced five decades ago, as opposed to a complicated full-suspension mountain bike.
Even if technology has advanced, how the bike fits you remains the most crucial factor. The rest will be easy if you get that right from the get-go.
Differences Between Expensive and Cheap Road Bikes
While maintaining the same frame configuration, entry-level road bikes will lose the most weight, have a smaller gear range, and have significantly heavier wheels and tires. Users of road bikes will often think of these as their initial upgrade. A basic road bike may weigh up to ten kilograms.
In the past 10 years, the development of suspension technology at two of the ride’s contact points has added ease and versatility to the roster. To optimize the experience of the ride on rougher road surfaces, such as cobbled streets, and lessen the “buzz” that may be perceived through a road bike’s frame structure and forks, seat posts and headsets can be softened.
This lessens the strain that riding puts on the limbs. Standard tire widths are 25 mm, and the majority of frames can now accommodate tires with a width of up to 28 mm without mudguards.
Road bikes have evolved beyond the confines of riding on asphalt. For the majority of cyclists, comfort has increased without significantly slowing down. They were further modified to produce gravel bikes. On the road bikes used by experts, you won’t find mounts for pannier racks, mudguards, or fenders, although they are popular in the midrange and lower.
3 Reasons Why Road Bikes Are So Loud
In this section, we’ll discuss the three most common reasons why road bikes are so loud. Keep reading below!
1. Carbon Rims
You might have noticed that the carbon rims on your expensive road bike are a little bit louder than the aluminum ones. Although carbon rims’ design makes them lighter and more svelte, it also makes freehub and road noise more noticeable.
Your road bike may sound different when you ride in different regions because various types of road surfaces produce various forms of noise and vibration. Since they aren’t as noisy, some individuals prefer aluminum rims.
Of course, there are many more potential causes of your road bike’s noise, some of which must be addressed for safety and effectiveness. But carbon rims are one of the most harmless reasons.
2. Higher-End Freehub
The so-called pawls, which are small, spring-loaded components meant to cling to the ratchet of the wheel while pedaling ahead, are what cause a rear hub to make noise, regardless of how expensive the model of the road bike is.
The pawls disengage and glide across the engagement area while coasting or pedaling backward. Higher-end hubs make louder, more abrasive noises because they employ stronger springs and have more pawls and engagement places.
Additionally, more modern hubs use lighter grease, which places less of a restriction on the springs’ range of motion.
The pawls extend and make contact with the ratchet’s teeth. As a result, the wheel starts to turn at the cyclist’s command. When the pawls bite into the ratchet, they become immobile and clamp against the inner teeth, and the sound stops.
The pawls begin to slide against the inner teeth during backpedaling and sink into their “beds” when they make a connection with a tooth. Since they are spring-loaded, whenever the rotation is reversed, they jump out and begin to bite once more.

3. Premium Cassettes
Rarely are expensive hubs the most expensive component on a road bike. And besides, it would seem a little strange to ride a $100 beater with a $200 hub. A road bike with a high-end hub is likely to have high-end components throughout. Surprisingly, the “orchestra” is also impacted by the other parts.
The bike’s cassette significantly affects the hub’s ability to produce sound. The rear hub’s buzzing is amplified in higher-end versions with solid, stronger, and lighter bodies as opposed to cheaper ones with plastic components that mask the sound. It’s not unusual for a hub to get noisier after upgrading the cassette on a bike.
Are Road Bikes Fit for Riding in Cities?
City cycling is not intended for road bikes. They are best used on smooth, broad highways free of metropolitan traffic needs like stop signs, traffic lights, and numerous curves. They encourage you to ride in a fixed, inflexible position that you must keep up for the entire distance.
For city riding, certain components of a lightweight road bike may be beneficial. Before the invention of electric bikes, chic bicycle couriers would spend most of their working days on road bikes that they had modified themselves to transport small parcels inside our cities.
They valued quickness and maneuverability. They reduced maintenance costs by switching to a fixed wheel or fixed hub and narrowing the drop handlebars.
Road bikes may surely assist you in moving rapidly across a city’s main thoroughfares. It is simple to maneuver on designated roads with broad bike lanes.
Road bikes are known for their speed and aerodynamics. Yet, their major drawback is the noise they create. While a lot of people find that appealing, most find it irritating. In this article, we discussed the reasons why road bikes are so loud.
