NEWBOLER Ultralight Bike Inner Tube 700C 18 25 28 Road Bicycle Orange

This inner tube should not be excessively inflated without 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%.

Product name: Inner tube of ultra light road bicycle
Applicable to: road bicycle 700x1 8C/23C/25C/28C/30C/32C
(Recommended scope of application)
Valve type: French valve
Feature 1: Small size, light weight, good toughness, and high cost performance
Feature 2: High temperature resistance, cold resistance, high elasticity, and tear resistance
Feature 3: Durable and recyclable
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.
