Recommended Applicability 1.1-1.5
Due to the special TPU material, the durability is also greatly improved compared with traditional inner tubes. The ultra-light weight is only 24g, which is about 100g less than the traditional butyl inner tube, and a pair saves 200g! At the same time, the inertia of the outer ring of the wheel set is reduced, making the sprint and acceleration more sensitive.

Notice:

The inner tube should not be inflated a lot when it is not turned into the outer tire, otherwise it will cause irreversible damage
Please inflate slightly to check for air leakage before installation!
When installing, first inflate 0.5PSL, make sure that the inner tube sticks to the inner wall of the tire when inflating, and then press and adjust the inner tube
If the vacant pump exceeds 6PSI, the expansion will not be repaired. Please remember that it is strictly forbidden to exceed 6PSI.

Installation Notes

The inner tube is made of TPU material, and it is strictly forbidden to pull the inner tube to test the elasticity! It is strictly forbidden to inflate in an empty state (not loaded into the tire)!

1-Put the inner tube into the tire in sequence starting from the valve.

2-When the inner tube is finished, adjust it to both sides and retract it into the outer tube in sequence.

3-Starting from the corresponding side of the air nozzle of the inner tube, the outer tire will be retracted to both sides in sequence.

4-If there is no downward adjustment and the pull-down is pulled back, the inner tube may be deformed or damaged when it is inflated!

Note: After assembling, please press the valve inward and close to the tire, and then pull the valve in the opposite direction.

5-Inflate 0.5PSI first, make sure the inner tube is close to the inner wall of the tire when inflating, and then press too much to adjust the inner tube.
