Tubeless or inner tube for gravel? Guide & comparison

Every year, thousands of cycling enthusiasts pack their gravel bikes to set off on epic multi-day journeys: traversing the Alps, riding around Mont Blanc, or embarking on self-supported bikepacking adventures across the globe. But when loading up your bags, one technical question always comes up: should you switch to a Tubeless setup or stick with traditional inner tubes?

Between the fear of an unfixable flat in the middle of nowhere and the quest for ultimate comfort on rugged tracks, your tire setup directly impacts the success of your trip. In this comprehensive guide written by GravelUp guides and experts, we compare both technologies to help you make the best choice based on your destination and riding style.

1. Tubeless setup for gravel touring: The king of off-road adventure?

The Tubeless system (a tubeless tire sealed with tubeless tape, a dedicated valve, and liquid sealant) has become the gold standard on modern gravel bikes. But is it perfectly suited to long-distance touring constraints?

Key benefits of tubeless for bikepacking

• Self-healing Puncture Protection: This is the superpower of tubeless setups. Small thorns, flint shards, and glass splinters are sealed instantly by liquid sealant without you ever having to stop.

• Zero Pinch Flats: When riding a heavy bike loaded with panniers, tires hit obstacles harder. Without an inner tube, pinch flats (pinching the tube against the rim) are 100% eliminated.

• Superior Comfort and Grip: Tubeless lets you run lower tire pressures (between 1.8 and 2.4 bar / 26 to 35 PSI depending on rider and gear weight). The result: optimal vibration damping, less muscle fatigue, and maximum traction on loose gravel.

• Optimal Rolling Efficiency: Removing the internal friction between the tire and inner tube improves pedaling efficiency on long tarmac or hardpack sections.

Limitations to keep in mind

• Sealant Maintenance: Liquid sealant dries out over time (every 3 to 6 months) and dries faster in hot climates. You must top up the sealant regularly.

• Installation Can Be Tricky: Seating a fresh tire or reinstalling a valve on the side of a remote trail without a floor pump or CO2 cartridge can be challenging.

• Major Sidewall Tears: If your tire suffers a slash wider than 4-5 mm, sealant alone won’t seal it. You must know how to insert a tubeless plug or fit a spare inner tube.

2. Inner tubes for bike touring: the choice of simplicity?

In use for over a century, inner tubes still have loyal followers, especially among traditional bicycle tourers and long-distance expedition riders in remote regions.

Advantages of Inner Tubes

• Universal & Available Anywhere: In the most remote village in the Andes or Central Asia, you will always find a compatible inner tube or patch kit.

• Mechanical Simplicity: No messy liquid, no special valves. Repairing a flat only requires tire levers, glue, and a patch.

• Long Shelf Life: An inner tube stays intact inside your pannier for years without drying out or losing performance.

Major Drawbacks for Gravel Riding

• High Puncture Rate: On gravel roads, rocky trails, and forest tracks, thorns and sharp stones lead to frequent, frustrating stops.

• Harsh Ride & Lack of Traction: To avoid pinch flats from heavy luggage, you are forced to over-inflate your tires (3.0 to 3.5 bar / 43 to 50 PSI). The bike becomes harsh, uncomfortable, and unstable on steep descents.

3. Comparison Table: Tubeless vs Inner Tube

💡 Expert Tip from GravelUp :

For our gravel trips and expeditions (Grand Causses, Vosges, Andalusia, Alps), our guides 100% recommend riding Tubeless. The gain in comfort, handling, and total freedom from frequent flat stops makes your trip infinitely smoother and more enjoyable.

4. The Ultimate Tubeless Trailside Repair Kit

If you choose to ride Tubeless (which we strongly recommend), here is the essential repair kit to carry in your frame bag:

1. Tubeless Repair Plug Kit (Bacon Strips) & Insertion Tool: To seal punctures too large for liquid sealant alone.

2. 1 or 2 Ultralight Spare Inner Tubes (TPU): In case of a major tire tear, remove the tubeless valve and pop in the inner tube to get home safely.

3. A 60 ml Bottle of Liquid Sealant: Crucial for refilling sealant after sealing a large puncture on the trail.

4. High-Volume Hand Pump & CO2 Cartridges: To quickly inflate tires and re-seat tire beads when needed.

5. Tire Boot / Sidewall Patch: To place inside the tire casing if the sidewall is sliced.

5. Verdict: What Should You Choose for Your Trip?

• 2 to 10-Day Trips in Europe / North America (Bikepacking, Micro-adventures, GravelUp Tours):

  Go Tubeless without hesitation! It offers the perfect balance of rolling speed, comfort, and puncture protection on marked trails.

• Multi-Month Remote Expeditions (South America, Africa, Asia):

  Ride Tubeless, but carry 2 TPU spare tubes and sturdy patches in your bags. If you run out of sealant in the middle of nowhere, you can easily convert back to inner tubes.
