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.Product name: Inner tube of ultra light road bicycleWeight: 28G, easy to carryValve length: 65mmMaterial: TUPApplicable to: road bicycle 700x1 8C/23C/25C/28C/30C/32C(Recommended scope of application)Color: Orange/Green/PurpleValve type: French valveFeature 1: Small size, light weight, good toughness, and high cost performanceFeature 2: High temperature resistance, cold resistance, high elasticity, and tear resistanceFeature 3: Durable and recyclable

PLEASE NOTE

★The inner tube cannot be filled with too much air when the outer tube is not installed. Otherwise irreversible damage will be caused.★Pump emptying over 8psi will result in irreparable swelling.★Inflate 0.5psi first when installing and check for leaks.Make sure the inner tube fits snugly against the inside of the inner tube tire when inflated, then the inner tube must be adjusted by pressure inflation!★Remember, it is strictly forbidden to exceed 8PSl in emptying!

★Remember, it is strictly forbidden to exceed 8PSl in emptying!

Ultra-lightweight inner tube with new TPU material for puncture resistance

★Made of a special new TPU material with excellent puncture resistance. Using integrated manufacturing technology, there are no signs of seams around the inner tube, only a ring of seams around the valve, reducing the possibility of air leakage.★Durable and stable tyre pressure, resistant to high and low temperatures, the stable tyre pressure ensures your safety.★At the same time, the inertia of the outer rim of the wheelset is reduced, allowing for more responsive sprinting and acceleration.★Available in orange, purple and green, the colours are bright and easy to recognise

Air core, replaceable

When your valve core breaks,You can change it and just rotate it to the right. When pumping, the one that rotates is the one above. The valve core is the lower one that rotates and is generally installed tightly. Use a little force, or use a tool to take it.

Inner Tube Assembly Steps

The inner tube is made of TPU and strictly forbidden to pull on the to test its elasticity!It is forbidden to inflate the inner tube when it is empty! (not mounted in the outer tube)Please follow the installation instructions below! (Mainly the installation direction)-Inner Tube Assembly Steps1. Starting from the valve part, put the tube into the tire orderly in one direction as illustrated.2. Then, do it orderly in the other direction as illustrated until the whole tube fits in.3. Starting from the opposite side of the valve (as illustrated), fit in the tire orderly in bothdirections simultaneously.4. lf no press and pull to adjust the valve, it may result in deformationor breakage while pumping, due to the valve being jammed inside.5. At 0.5 psi, massage and adjust the tube to fit into the rim.Adjust the tube-lts important to massage the tube at 0.5 psi.-This step will prevent the tube from not fully expanded.
