In this article you will learn: What types of gravel exist, how they behave on the road and what you should pay attention to – both in the planning and during the ride.
Fine gravel / gravel roads (also known as "hardpack gravel")
What is that?
Fine gravel or hardpack are paths consisting of very small, closely packed gravel and sand particles. Often lightly compacted, they are frequently found in parks or forested areas.
How does it drive?
-
Fast: One of the fastest gravel surfaces ever.
-
Stable: Tires roll smoothly and evenly.
-
Predictable: Minimal offset and hardly any loose stones.
What should you pay attention to?
-
Tire widths of 35–40 mm are ideal.
-
A light profile is perfectly sufficient.
-
Perfect for longer tours when an asphalt feel is desired.
Coarse gravel / “Chunky Gravel”
What is that?
Coarse, unevenly distributed gravel with stones approximately 2 cm in size and larger. Often found on newly constructed forest roads, farm tracks, or construction sites.
How does it drive?
-
Unsteady and bumpy – the handlebars tend to wobble.
-
Slow rolling resistance: power is lost, speed decreases.
-
Increased risk of snakebites (punch-throughs).
What should you pay attention to?
-
Wide tires (40–45 mm or more) provide safety.
-
Tubeless is highly recommended.
-
Springy arms and a gaze far ahead: Recognize dangers early.
Washboard (Corrugated Gravel)
What is that?
Wavy ruts caused by car traffic. One of the most unpleasant types of gravel – the name is well-deserved.
How does it drive?
-
Hard and vibrating: Extremely uncomfortable.
-
Unstable: The bike “jumps”, contact with the ground worsens.
-
Unpredictable: Tricky on fast descents.
What should you pay attention to?
-
Reduce air pressure (0.2–0.5 bar less).
-
Drive loosely: Excessive tension impairs control.
-
Look for a better line: Often the edge of the path is smoother.
Forest floor with gravel content
What is that?
A mix of soil, roots, leaves, and occasional gravel. Very variable – it can be hard, soft, dry, or muddy.
How does it drive?
-
Variable: Grip can change every second.
-
Easy to ride in dry conditions , significantly more difficult in wet conditions.
-
Slippery surfaces due to leaves, roots, or damp areas.
What should you pay attention to?
-
Profiled tires offer more safety.
-
Keep tire pressure rather low to maximize grip.
-
Practice weight shifting: consciously unload the front and rear wheels.
Fine, deep gravel / “sand gravel”
What is that?
Loose, deep surfaces of fine, dry gravel or sand. Primarily found near coastlines, floodplains, or open agricultural areas.
How does it drive?
What should you pay attention to?
-
Shift your seat position backwards to relieve pressure on the front wheel.
-
Gentle steering movements: Any hectic movements will cause the car to slip.
-
Wide tires (45 mm+) are worth their weight in gold.
Compacted natural path with gravel
What is that?
Paths consisting of a solid clay base onto which a thin layer of gravel has been spread – often found in communities or parks.
How does it drive?
-
Very pleasant , as long as it's dry.
-
It gets slippery when it rains , because the clay layer becomes slippery.
-
Good grip , but be careful in curves.
What should you pay attention to?
-
Tire pressure moderate – not too hard.
-
Adjust speed if the surface is shiny (an indication of damp spots).
-
Avoid gravel edges that can push the tires away.
Why knowledge about gravel types is important
Gravel riding means freedom – but freedom only works if you know what's happening under your tires. Choosing the right tires, the correct tire pressure, and your riding style depend directly on the surface.
Those who know the differences drive more safely, faster and with more fun.
Tips for perfect gravel performance
✔️ 1. Tire selection according to terrain
-
Fast & firm: Semi-slick tires
-
Versatile: All-round gravel profile
-
Technical & rough: Tread pattern
✔️ 2. Air pressure makes the biggest difference
More grip = less pressure
More speed = more pressure
As a rough guide:
✔️ 3. Adjust your posture
-
Stay relaxed: Use your arms and upper body as cushioning.
-
Looking far ahead: Recognizing dangers early.
-
Shift your weight in a controlled manner: depending on your grip requirements.
✔️ 4. Determine the line as in MTB
The same applies to gravel riding: the best line is not always the middle of the path.
The right tires for gravel riding – and what you should always have with you
Tire choice is more crucial for comfort and control when gravel riding than any other component. Fast semi-slicks or tires with a shallow center tread (35–40 mm) are ideal for hardpack and fine gravel . They roll efficiently while still providing sufficient cornering grip. If you frequently ride on rough gravel , forest trails, or technical sections, wider tires (42–45 mm) with a more pronounced tread pattern offer more grip and safety. For those primarily planning adventure rides, bikepacking, or exploring unfamiliar terrain, 50 mm+ tires are a safe bet – comfort and puncture resistance increase significantly.
To ensure you're never stranded on your rides, you should always carry a small basic kit: a multi-tool, two tire levers, a mini pump or CO₂ cartridge, a spare inner tube, a tubeless plug kit, and a chain lock . Additionally, a small first-aid strip , cable ties, and some duct tape are recommended – they can save the day in a surprising number of situations. The more remote the ride, the more important this basic equipment becomes.
Gravel is versatile – and that's exactly what makes it so exciting.
Getting started is easy if you go out with the right expectations. It's best to begin with short rides on hardpack, well-maintained dirt roads, and forest trails – this will give you a feel for the different surfaces without overexerting yourself. Gradually work your way up to more challenging sections and consciously experiment with tire pressure, body position, and line choice to feel how the bike reacts. Many find their way into riding via komoot or Strava routes , which can be filtered by technical difficulty. You'll get into it even faster if you ride with experienced riders – technique, confidence, and flow will come much more quickly.
Not all gravel is created equal. Whether fine, coarse, deep, or hard: every surface has its own characteristics. Knowing what to expect allows you to react better, ride more safely, and enjoy your gravel adventures even more.
Gravel riding begins where the asphalt ends – and ends where you don't want to go any further. With the right knowledge, you can go further. Much further. 🚵💨
