Tubeless Tyre Sealant Explained: Why Latex-Free Sealant Is Better
Tubeless Tyre Sealant Explained: How It Works and Why Latex-Free Sealant Is Changing the Game
Tubeless tyres have become the standard for mountain biking, gravel riding and increasingly road cycling. They offer better grip, fewer punctures and the ability to run lower tyre pressures.
But the real hero of any tubeless system is something most riders rarely think about:
Tubeless tyre sealant.
Without it, your tubeless tyres simply wouldn't work.
Sealant instantly plugs punctures, maintains air pressure and allows riders to keep rolling when traditional tubes would have failed. But not all sealants are created equal, and the technology behind them is evolving quickly.
How Tubeless Tyre Sealant Works
Tubeless sealant is a liquid compound that sits inside the tyre.
When a puncture occurs, air escaping from the tyre carries the sealant toward the hole. As the liquid reaches the puncture, it rapidly forms a plug that seals the gap and prevents further air loss.
This process happens almost instantly, which is why many riders never even realise they’ve punctured their tyre.
Good sealants are designed to:
- seal punctures quickly
- remain liquid for long periods
- resist drying out inside the tyre
- work across a wide range of temperatures
The Problem With Traditional Latex Sealants
For years, most tubeless sealants have been based on natural or synthetic latex.
Latex works well for sealing punctures, but it comes with several drawbacks.
Over time, latex sealants tend to:
- dry out inside tyres
- form rubbery clumps
- clog valves
- require frequent top-ups
Latex sealants can also cause allergic reactions for some riders and may not be environmentally friendly when washed out during tyre changes.
Because of these issues, many riders are now looking for latex-free tubeless sealant alternatives.
The Rise of Latex-Free Tubeless Sealant
Modern latex-free sealants are designed to overcome many of the problems associated with traditional formulas.
A good latex-free sealant should:
- stay liquid longer
- resist clumping
- remain stable in extreme temperatures
- seal punctures quickly
- be easier to clean during tyre changes
These advantages are why more riders are switching to eco-friendly latex-free tubeless sealants.
GNARLY Tubeless Tyre Sealant
GNARLY Tubeless Tyre Sealant was developed as an eco-friendly, latex-free solution that delivers reliable puncture protection without the drawbacks of traditional sealants.
Designed for mountain bikes, gravel bikes and road bikes, GNARLY sealant works in all tubeless tyres.
Key features include:
- seals punctures up to 6mm instantly
- latex-free, non-toxic formula
- long-lasting liquid performance
- compatible with MTB, gravel and road tubeless systems
- easy cleanup without rubber clumps
Because the formula stays liquid longer, riders spend less time topping up sealant and more time riding.
Why Latex-Free Sealant Makes Sense
Latex-free sealants offer several practical advantages for modern riders.
Longer Service Life
Because the formula resists drying out, latex-free sealants can remain effective inside the tyre for months.
Cleaner Tyre Changes
Without latex forming rubber balls inside the tyre, cleaning becomes much easier when replacing tyres.
Safer and More Eco-Friendly
Non-toxic formulas reduce environmental impact and avoid potential allergic reactions.
How Much Tubeless Sealant Should You Use?
The amount of sealant required depends on tyre size.
Typical guidelines are:
|
Tyre Type |
Recommended Sealant |
|
Road tyres (23–32mm) |
30–40ml |
|
Gravel tyres (35–50mm) |
50–70ml |
|
MTB tyres (2.2–2.6") |
80–100ml |
|
Fat bike tyres |
150–200ml |
Always shake the bottle before use to ensure the sealant mixture is evenly distributed.
If you are running tubeless tyre inserts, most sealant brands suggest adding up to 50% more sealant depending on the type of insert used.
How Long Does Tubeless Sealant Last?
Sealant longevity depends on climate, tyre casing and riding conditions.
In most cases:
- 4–6 months in moderate climates
- 2–3 months in hot environments
Checking sealant levels periodically ensures your tubeless system remains reliable.
How to Install Tubeless Sealant
Installing sealant is simple.
- Shake the bottle thoroughly
- Add the recommended amount through the valve or tyre bead
- Inflate the tyre to seating pressure
- Spin and shake the wheel to distribute sealant evenly
Once installed, the sealant coats the inside of the tyre and remains ready to seal punctures instantly.
