Road Bike vs. Gravel Bike: Which is Right for You?
What are road bikes and gravel bikes for?
While road bikes are typically built for the high demands of racing and speed, gravel bikes are designed to provide a comfortable and versatile riding experience in a variety of conditions.
Road bikes are specifically designed for high-speed riding on smooth asphalt roads. Thanks to their unique geometry and narrow tires, they are light and maneuverable.
In contrast, gravel bikes are built for adventurous terrain and can ride over rough and rocky surfaces with ease. Their geometry is designed more for stability, which leads to an upright posture. The wide tires can absorb road shocks much better than on racing bikes.
Geometry
Road bikes are designed to meet the demands of racing and speed, while gravel bikes offer a versatile riding experience in different conditions.
Road bikes are designed to provide a responsive, aggressive, and aerodynamic riding position known as "racing geometry." The main aim is to optimize power transfer and efficiency so that the driver can achieve peak performance at high speeds. Road bikes typically have a shorter wheelbase, a higher height and a higher head tube stem, which means the body position is flatter, improves aerodynamics and allows you to reach your top speed. Road bikes have a lower bottom bracket than gravel bikes. This means the driver's center of gravity is lower, which gives him more safety when cornering and descending at high speeds.
Gravel bike frames are designed with a slacker head tube angle and a higher stack, resulting in a more upright rider posture. This upright position provides greater stability, control and comfort when riding over rough and uneven terrain. Due to the higher stack, gravel bikes typically have a sloping top tube.
In addition, gravel bikes have a longer wheelbase, which makes them more stable and allows for larger tires. This longer wheelbase also helps ensure that the toes do not overlap with the front wheel, which is essential for safe handling on uneven and technical roads.
Another important feature of gravel bikes is the higher bottom bracket, which provides more ground clearance for the pedals. This feature is crucial when riding on uneven terrain as it helps prevent pedal shock.

Wheels
There are two main differences between road bikes and off-road bikes.
The first is rim depth. Since road bikes typically reach higher speeds, many riders prefer deeper rims of around 40-60mm to achieve aerodynamic advantages. The ICAN AERO Disc series is a best-selling product known for its aerodynamic design. The rim depth can be chosen between 40 mm, 50 mm and 55 mm, while the rims for gravel bikes are rather flat and lie between 30 and 45 mm. The ICAN G24, for example, has a rim depth of 40 mm. This helps the wheels remain maneuverable at typical speeds in gravel use.
The second difference is the inner rim width. Road bike wheels typically have a maximum internal width of 21 mm, while gravel bike wheels are typically between 21 and 25 mm wide. The ICAN G25 has an internal width of 25 mm. This additional width supports wider tires, allowing for better tire feel when cornering and the ability to use lower pressures. Additionally, the larger inner rim width allows full use of tubeless tires.
tire size and tire pressure
Tires play a crucial role in the performance of your bike. Typically, wider tires provide more grip and allow you better balance and control. On the other hand, thinner tires offer a smoother ride because they have less contact area with the ground, resulting in lower rolling resistance and higher speeds.
Gravel bikes are designed for wider tires, usually 40 to 45 mm. This increases stability and ensures better grip on uneven surfaces. Road bikes, on the other hand, typically have narrower tires (25 to 28 mm) to optimize speed and minimize rolling resistance on paved roads.
Road bikes are designed to minimize rolling resistance by using tires with a width of 23-25 mm and an air pressure of 90-100 PSI. This setting allows for faster rolling, but can also result in a bumpy ride. On the other hand, gravel bikes require a wider tire to ensure better traction on mixed surfaces. Typically a tire with a width of 30-40 mm and a lower pressure of around 40 PSI is used, which allows the tire to absorb bumps and reduces the risk of punctures.
Road bikes are designed for high speeds on smooth, paved roads and have narrow, high-inflation tires. Gravel bikes, on the other hand, are designed for rough terrain and have wider, lower pressure tires that can handle a variety of treads and sizes.
The maximum width of tires that can be used on a bicycle is determined by the clearance between the fork, seatstays and chainstays. Gravel bikes typically have more clearance to accommodate a wider range of tire sizes and profiles. This is particularly important in wet and muddy conditions as it allows enough space to prevent the tires from becoming clogged with mud.
Links
Road bikes are usually equipped with shorter and narrower handlebars. The sloping part of the handlebar goes straight down to keep the rider's body shape as compact as possible. This reduces the contact area with the wind and improves aerodynamics.
Gravel bikes, on the other hand, are equipped with flare handlebars. This means that the lower part of the handlebars slopes towards the outside of the bike at an angle. The flare handlebars give the rider's arms more room to move and maneuver the bike more freely. This improves control and stability when driving on rough terrain.
Brakes
Disc brakes have long been common on mountain bikes. However, they have only recently become popular among racing cyclists. Some riders still prefer rim brakes because they are lighter. On the other hand, disc brakes are only used in gravel bikes. They offer better braking performance on different surfaces and are therefore more reliable and efficient.
gears
Road bikes traditionally have two or three chainrings at the front and a narrower cassette range at the rear. This is because road bikes are designed for higher speeds and steep inclines and therefore require a wide range of gears. Today, cassettes typically range from 11-28t to 11-34t, and chainrings are typically arranged in a 53/39, 52/36 or 50/34 configuration, although other options are also available.
Gravel bikes have a different gear system than regular bikes. They are usually equipped with one or two chainrings. A single chainring eliminates the need for the front derailleur. Gravel bikes are typically ridden at a slower pace, and riders require larger gears in the cassettes to climb steep gravel hills on loose surfaces. Cassettes with 10-42t to 10-52t are usually used. A gear system with two chainrings usually has smaller chainrings, e.g. B. 46/30t or 48/31t.
FAQ
Can I use my gravel bike on the road?
In any case! Gravel bikes are designed to perform well both on and off-road. This makes them a popular choice for cyclists who prefer a single bike that meets all their needs. Whether you're commuting to work or hitting the trail, your gravel bike is a versatile and reliable option.
Is a gravel bike more comfortable than a road bike?
Gravel tires may not roll as quickly on the road, but they are wider and have lower pressure, making them more comfortable to ride on any type of road surface. Some gravel bikes have rear suspension and optional front suspension, further increasing ride comfort.
Is driving on gravel more difficult than on the road?
Riding on gravel is more difficult than on the road because the looseness and irregularity of gravel provides a less stable surface, making the bike's handling more unpredictable.
Is a gravel bike suitable for beginners?
A gravel bike is ideal for beginners as it can handle different terrains and surfaces, making it versatile.
