Products Description
high quality
Our 700x38c Bike Inner Tube is made from high-quality rubber with 45% rubber content, ensuring durability and long-lasting performance.
Tire pressure directly affects riding comfort and performance. Tire pressure is usually expressed in PSI (pounds per square inch) or BAR (bar).
Wide Range of Sizes:
Available in multiple sizes, including 26x3, 26x2.125, 27.5, 700*23-25,700*35-38, and 29 inches, to fit various wheel sizes and meet different user needs.
Confirm the size and width of your bike's tires so you can choose the appropriate inner tube. The tire size is usually marked on the tire, such as 700x38c bike inner tube (road bike) or 27.5x2.1 (mountain bike).

Valve Description
The valve is an indispensable and very important part of the bicycle's inner tube.
Presta valve
Presta valves in bicycle inner tubes come in different lengths
Adapt to rims of different heights:
Presta valves are available in a variety of lengths to accommodate rims of different heights. For example, valves of different lengths, such as 35mm, 48mm, 60mm, and 80mm, can correspond to rims of different heights, ranging from less than 25mm to 50~70mm. This design ensures that the valve protrudes from the rim long enough to facilitate operation when inflating.
Presta valve
Meet the needs of different types of bicycle tires
Maintain air tightness and rim strength:
Due to its thinner valve stem, the Presta valve only needs to make a small hole in the rim, which can reduce the impact on the rim's strength. At the same time, the Presta valve is very airtight at high pressure, which is very important for road tires that require high air pressure.
700x38c bike inner tube require high air pressure, so most of them use Presta valves.
