What Is A Gravel Bike

As the name suggests, a gravel bike is a bike built specifically to be used on poorly-maintained roads, on paths and downhill, although the frame and the overall aspect of the bike resemble more a road or urban bike than an MTB.

Before talking about technology, components and make, we should focus on what a gravel bike is designed to do, so you can understand if this can be the right choice for you.

At a first glance, a gravel bike might seem to be a racing bike designed for the off-road, but the reality is different. In fact, this type of bike has a more upright and aerodynamic design, favoring stability and comfort on the saddle. After all, the goal of a gravel bike is that of covering many miles a day on traces alternating asphalt, dirt roads, as well as undemanding trails.

To reach this goal, the inventors of the gravel bike studied a frame with relaxed geometries, with a longer rear chassis and an opened angle saddle, decisions that increased the wheelbase and the footprint of the bike, giving it more stability.

Since the main problem when pedaling on dirt roads or gravel roads is the lack of stability and grip, it is easy to understand why many off-road passionate consider gravel bikes the best compromise between an urban bike and an MTB.

On the other hand, the seat tube is less vertical, a choice that allows cyclists to have a more upright position in the saddle and that also has a vibration damping effect.

This being said, let’s find out more about the technical characteristics of a gravel bike.

Technical Features Of The Gravel Bikes

Frame

Typically, gravel bike frames are made either of aluminum or carbon fiber. In the first case, the main structure of the frame, namely the front quadrilateral and the rear chassis are made of aluminum with a carbon fiber fork. In the second case, the full frame is usually made of a composite that is extremely resistant, presents an excellent absorption of the vibrations and a lower rigidity compared to other types of frames. The geometry is relaxed, with an inclined seat tube, an opened steering angle and longer wheelbase for increased stability. The chainstays allow the mounting of larger tires and the wheel attachment utilizes an increased diameter.

Headset

The technology used the most in the case of the gravel bikes is the integrated headset with races integrated into the head tube where are housed industrial type cushions. To increase stiffness and impact resistance, the headset is conical and it has a diameter of 1 1/8 inches on the top and 1 1/4 or even 1 1/2 inches at the bottom. This solution increases the stress resistance and the connection zone between the headset and the fork head.

Internal Cable Passage

Gravel bikes use the same solution that was originally designed for the MTB, namely the gear shift and brake cables pass through the frame to avoid problems such as ripening off the cable, accumulation of dust and annoying sliding. This solution also offers an aesthetic advantage.

Wheels

Gravel bikes have a low profile using 700C circles. The rays are often shredded or flat. The ideal dimensions of the wheels of a gravel bike are 28 inches, even though some gravel bikes come with 27,5 inches wheels that accommodate tires of various sizes.

Transmission

Gravel bike’s transmission is quite similar to one of the racing bikes, with a double front and a sprocket pack of 10 or 11 speeds for the rear wheel. The difference between the two types of bikes is the number of teeth of the gears. In most of the cases, brake and gear controls are integrated and some models even propose electromechanical transmissions.

Disc Brakes

Gravel bikes are born with disc brakes, usually with rotors of 160mm in diameter. Disc brakes offer a superior braking power with a lever modularity and stable performance even on muddy terrains. The different models of gravel bikes can have either mechanical or hydraulic disc brakes and the choice of one type over the other depends on personal needs and preferences.

Handlebar

The handlebar of the gravel bikes is ergonomic and designed for increased comfort during use. The various controls are positioned within easy reach, the handlebar allows a leaner grip and increases the stability on the bike.

Saddle

The saddle of a gravel bike should be less aerodynamic and less light than the saddle of a racing bike. It should be designed to provide increased support to the spine and it should have great vibration absorption characteristics. Nevertheless, the saddle is a matter of personal preferences and choice, therefore it can be easily customized to one’s needs.

Pedals

Gravel bikes use the same quick release pedals typical of the MTB. This type of pedals are extremely comfortable and they offer excellent performances on any type of terrain. But just as for the saddle, the choice of the pedals is personal and the model can be easily adjusted to one’s needs.

By now you should have decided if a gravel bike is a right bike for you. If it is, our best gravel bike reviews below will help you choose the best from the most popular models available on the market.
