Key Features
- TPU Material — The tube is made of TPU, a flexible material that holds air inside the outer tire.
- French Valve Option — It has a French valve, offered in 45mm, 65mm and 85mm lengths to suit different rim depths.
- Pressure Limit — Tire pressure must not exceed 5 bar/72 PSI when used with rims that have a no-ring-lip system, per ISO/TC 31.
- Temperature Effect — Every 3°C (5°F) rise in temperature raises tire pressure by about 1%, so pressure can climb on hot pavement.

What It Is / How It Works
This RideNow bicycle inner tube is a replacement tube that sits inside the outer tire and holds the air that supports the tire. It is made of TPU.
Who It's For / Use Cases
Inner tubes suit riders who need to replace a worn or punctured tube in a bicycle tire. They also fit riders who want to keep a spare tube on hand for road or trail rides, and riders who want to match the valve length to their rim depth.
How to Use / Care
- Do not inflate the tube much while it is outside the outer tire, because this can cause irreversible damage.
- Use a manual air pump rather than high-speed air filling equipment such as air compressors or pumps.
How to Choose
Start with the tire size your bicycle uses, then check the tube size against that tire. Choose the valve length by the depth of your rim, since a longer French valve reaches further through deeper rims. Keep the valve length and tire size in mind when comparing tubes in the Product Specifications section.
Frequently Asked Questions
What valve does this inner tube use?
It has a French valve, offered in 45mm, 65mm and 85mm lengths.
What is the tube made of?
It is made of TPU.
What is the maximum tire pressure?
Tire pressure must not exceed 5 bar/72 PSI when used with rims that have a no-ring-lip system, according to ISO/TC 31.
Why should I avoid inflating it outside the tire?
The tube cannot be inflated much when it is not installed in the outer tire, because it will cause irreversible damage.
How does temperature change the pressure?
Every 3°C (5°F) rise in temperature raises tire pressure by about 1%. Inflating in a cool garage at 18°C (65°F) and riding at 35°C (95°F) may raise tube pressure by about 0.5 bar/8 PSI.
