In the last few years, gravel bikes have been a hot topic for discussion in the cycling world. In fact, the rising popularity of gravel racing has made many pros believe that this is not a passing fad.

Gravel bikes offer excellent versatility to regular bikers looking to explore beyond road bikes. Those who are looking to venture beyond the smooth asphalt will find gravel bikes an exciting option. But, for casual riders, the speed and lightweight design of road bikes are important factors.

Before you explore the topic of gravel bikes vs road bikes, know that they are designed for different environments. Even though these two types may look similar, once you scratch the surface, you will find multiple key differences.

In a nutshell, the road bikes are designed for the tarmac and offer a speedy ride. On the other hand, a gravel bike comes with a rugged design that offers more comfort and reliability on rocky, sandy, or dirt trails.

This doesn’t mean that road bikes can’t tackle gravel roads. But their performance comes with a few limitations. A gravel bike is more versatile and is equally capable on the tarmac or on rougher terrain.

In this article, I will break down the major differences between the two to help you get a clear idea.

Main Differences of a Gravel Bike vs Road Bike 

The main differences between gravel bike vs road bike are:

  • Road bikes have an aggressive geometry for fast and efficient rides, whereas the geometry of gravel bikes ensures a more relaxed and comfortable ride. In gravel bikes, the focus is to offer more clearance and better stability on tougher terrains.
  • Road bikes come with narrow tires with a smoother tread pattern, whereas gravel bikes have higher tire widths and a more rugged tread.
  • Road bikes are built more for speed and balance, whereas gravel bikes are designed with a more durable structure.
  • Road bikes use rim brakes or drum brakes, whereas gravel bikes come with disc brakes.
  • Road bikes have a lower gearing range as they are for tackling tarmac only, whereas gravel bikes come with a wide range of gearing to handle steep climbs.

Actually, the most striking difference between the two bikes is the wheel and tire sizes. Many of the other differences are nuanced and can go unnoticed unless the two bikes are placed side by side. 

However, these factors can make a big impact when it comes to real-world performance. Basically, road bikes are designed to offer the right rhythm, responsiveness, and high speed. But gravel bikes are all-rounders that can handle any terrain.

Feature Comparison: Gravel Bike vs Road Bike 

Note, even though all road bikes look similar, there can be subtle differences that affect the ride quality. Broadly speaking, road bikes can be classified into three types- race bikes, aero bikes, and endurance bikes.

In essence, gravel bikes are an upgraded version of the road bike that makes them perfect for multiple cycling activities. The only aspect where gravel bikes lack is they are not designed for speed.

Here is an in-depth comparison between the two based on the main features.

The Geometry and Design

In gravel bikes, the head tubes are longer, and the head angles are more relaxed. This makes the ride higher and improves the overall stability and comfort levels. Also, the handling is slowed down for tackling obstacles and tricky descents.

Other geometrical changes in gravel bikes include a sloped top tube compared to the flat ones in a road bike. This makes steering the bike easier. The bottom bracket is also elevated to offer more ground clearance. 

In addition, gravel bikes also have a broader wheelbase that increases the overall stability. This also ensures more comfort for the rider over long distances.

In comparison, road bikes come with a more aggressive design that makes the rider sit lower and in a more aerodynamic position for faster and efficient rides. The steeper head angles also make the handling livelier.

Another common feature in gravel bikes is flared drop bars. These provide additional stability and more control, especially during steep descents. The bars usually come with a shallow drop to maximize rider comfort.

Some high-end gravel bikes also have a dropper seat post. This allows you to raise or lower the saddle during steep or rough descents.

Wheels and Tires

Road bikes use the standard full-size 700C wheel. Gravel bikes usually come with the 700C but they can be used with 650b wheels as well. This gives you the ability to use wider tires if needed.

Most road bikes come with tires that are between 23 to 25mm. The pressure is also kept high at around 90 to 100psi. The aim is to reduce the rolling resistance as much as possible. While this makes the bike faster, the ride quality and comfort levels are significantly reduced.

Gravel bikes come with wider tires ranging between 35 to 47 mm. This allows them to run at lower pressures of around 40psi. With a wider contact with the ground, you get lower rolling resistance.

The result is better ride quality and more traction over tricky terrain. The extra width also helps in negotiating the rough patches.

Besides, gravel bike tires also come with more aggressive tread patterns. Depending on the trail, you can pick special trad that can tackle softer surfaces and offer more grip.

For example, you can use a diamond tread on dry trails. However, more aggressive patterns with additional side lugs will be useful in mud or slush.

Gearing and Brake 

The gearing option in road bikes is designed to ensure that jumps between gears remain smaller. A typical gearing configuration consists of dual front chainrings paired with an 11-33 cassette. 

Since gravel bikes need to tackle a wide variety of terrain, they have a wider range of gearing. They can come with both single-chainring and double-chainring systems. These can be paired with an 11-40,11-42, or 11-34 cassette as needed.

In a 1x drivetrain, the jumps between the gears are more noticeable. Gravel bikes also have a clutch mechanism on the rear derailleur for eliminating chain slap.

All gravel bikes come with hydraulic disc brakes that deliver excellent stopping power and a high level of precision. You can confidently use them in rough conditions. 

Traditional rim-style braking systems are mostly used in road bikes. However, disc brakes are becoming common in road bikes as well.

Durability

Perhaps unsurprisingly, a gravel bike comes with a more durable structure than a road bike. A gravel bike frame can be made from carbon fiber, titanium, aluminum, or steel. But the material can have an impact on the price of the bike.

Needless to say, each material has its own set of pros and cons. In general, manufacturers prefer using carbon fiber as the frame material to balance durability with ride comfort.

That makes gravel bikes heavier. The tubes need to be thicker for withstanding abuse and heavy stresses while gravel riding.

In addition, gravel bikes are also designed to carry the extra weight of bags or extra gear, without affecting performance. They also have eyelets on the frame for mounting racks, fenders, or frame bags.

Mounts 

Another important feature of gravel bikes is unlike road bikes, they have multiple mounts for accessories. The bike structure is designed to accommodate the extra weight of the luggage.

In most cases, finding safe drinking water is difficult on off-road trails. So, gravel bikes have mounting points for bottle cages. There can also be bolts below the down tube for carrying an extra water bottle.

Additional eyelets can also be helpful for fitting a mudguard or a feed bag on the top tube. In some bikes, the fork crown can have a special mount for fixing a dynamo light.
