Road bike bicycle ultralight bicycle inner tubes

This inner tube should not be excessively inflated without being installed to the outer tube, as this can cause irreversible damage!

Please use a manual air pump instead of a high-speed inflation device such as an air compressor or pump.

Before inflating the inner tube, turn the valve inward (toward the center of the rim). Inflate a small amount of air until the inner tube is circular; This pressure should be less than 0.5 mm.

This pressure should be less than 0.5 bar/8 psi.

When using rims without a ring fastening system in accordance with ISO/TC 31, the tire inflation pressure should not exceed 5 bar/72 PSI.

Every 3 ° (5 ° F) increase in temperature increases the tire pressure by approximately 1%.

If you inflate your tires in a cool garage (18 ° C/65 ° F) in the morning, and then drive at higher ambient temperatures (35 ° C/95 ° F),this may cause an increase in inner tube pressure (e.g., 0.5 bar/8 psi).

Especially when driving on hot black asphalt with temperatures exceeding 65 ° C (150 ° F),the tire pressure may easily exceed the maximum allowable value. In addition, excessive tire pressure during cycling can lead to separation of the tire from the rim, leading to a risk of injury.

If pneumatic tires are stored at temperatures of 60 ° C (140 ° F) or higher (for example, in a car in hot weather),deflate the inner tube to 1 bar/15 psi to avoid valve deformation.
