FAQs
How does the self-sealing work?
The inner tube contains a sealant that is designed to instantly fill punctures up to 3mm in diameter, minimizing air loss.
What tire sizes are these tubes compatible with?
These tubes are compatible with 700 x 192 tires. Always check your tire size before installation.
Can I use these tubes with any type of tire?
Yes, but ensure you are using the correct size for your tires. Also, the sealant works best on punctures to the tread, not necessarily sidewall cuts.
How long will the sealant last?
The sealant's effectiveness can last for the life of the tube, but this depends on storage conditions, frequency of use, and the number and size of punctures. It is recommended to inflate the tire to the recommended pressure before each ride.
What do I do if the tube doesn't seal a puncture?
If the puncture is too large, the sealant may not be able to seal it. In this case, you'll need to patch or replace the tube.
Is the sealant harmful to the environment?
No, the sealant is water-based and anti-corrosive, making it harmless to the environment.
How do I store the inner tubes?
Store them in a cool, dry place away from direct sunlight.
Can I use a pump with a Presta valve?
Yes, the tube is compatible with Presta valves. Ensure your pump is compatible as well.
Troubleshooting
Tire is losing air despite the tube being installed.
Check the tire for the puncture. Make sure the valve is properly seated and not leaking. If the puncture is too large, you may need to patch the tube or replace it.
Sealant isn't sealing the puncture.
Ensure the puncture is within the 3mm diameter limit. Check tire pressure – low pressure can hinder sealant effectiveness. If the puncture is on the sidewall, the sealant may not work effectively.
Tube is difficult to install.
Make sure the tire is properly seated on the rim. Use tire levers to carefully pry the tire over the rim, being cautious not to pinch the tube. Inflate the tube slightly before installing it to give it some shape.

Setup, Compatibility & Care
- Compatibility: These inner tubes are designed for 700 x 192 tires. Always check your tire size before installation.
- Installation: Installation is similar to a standard inner tube. Carefully insert the tube into the tire, ensuring it's not twisted. Start by inflating the tube slightly to give it shape. Then, insert the valve through the valve hole in the rim and seat the tire beads.
- Inflation: Inflate the tire to the recommended pressure indicated on your tire sidewall. The sealant works most effectively when the tire is properly inflated.
- Care: Regularly check your tire pressure and inflate as needed. Store spare tubes in a cool, dry place away from direct sunlight.
- Inspection: Periodically inspect your tires for any signs of damage or wear that could lead to punctures.
