FAQs
What is the main advantage of butyl rubber for inner tubes?
Butyl rubber is known for its excellent air retention and durability, making it a reliable and cost-effective material for everyday cycling.
Can I use this tube on a bike with Schrader valves?
No, this tube is specifically designed with a Presta valve. You would need an adapter or a tube with a Schrader valve.
What does '0.9mm wall thickness' mean for performance?
A 0.9mm wall thickness provides a good balance between reducing weight and offering resistance to punctures and abrasions commonly encountered during riding.
How often should I check the air pressure in this tube?
For optimal performance and to prevent pinch flats, it is recommended to check the tire pressure before every ride, or at least weekly.
Is this tube suitable for high-performance racing?
While reliable for general use, butyl tubes are typically heavier and offer less rolling resistance than latex or tubeless setups, which are often preferred for competitive racing.
What is a removable valve core?
A removable valve core allows you to easily inflate the tire, add sealant, or replace the core if it becomes damaged. It can improve airflow for faster inflation.
Troubleshooting
Tube won't hold air
Check for leaks by submerging the inflated tube in water. Inspect the valve stem for damage or a loose base. Ensure the tire bead is properly seated and there are no sharp objects inside the tire or rim strip.
Pinch flat during installation
Ensure the tube is not twisted and is evenly seated inside the tire before full inflation. Partially inflate the tube first to give it shape, then seat the tire bead carefully. Avoid using tire levers in a way that could pinch the tube.
Valve stem leaks
Tighten the valve lockring (if present) and ensure the valve core is securely seated. For removable cores, use a valve core tool to tighten it. If the leak persists, the tube may be defective.

Setup, Compatibility & Care
Setup: Ensure your tire is compatible with the 20" x 1.25-1.5" size and the Presta valve. Remove the old tube, check the inside of the tire for any sharp objects, then install the new tube, partially inflating it to give it shape before seating the tire bead. Inflate to the recommended pressure indicated on your tire sidewall.
Compatibility: This tube is compatible with 20-inch bicycle rims designed for tire widths between 1.25 and 1.5 inches. It requires a pump with a Presta valve head. Always verify your rim's valve hole size and tire compatibility before purchase.
Care: Store tubes in a cool, dry place away from direct sunlight and sharp objects. Regularly check tire pressure and inspect tires for wear or damage. When not in use, keep the tube slightly inflated to prevent creases.
