TUP Puncture Resistant Material, the new TPU material has excellent puncture resistance. It is one-piece with no slits around the inner tube and only a ring of fittings around the valve, reducing the possibility of air leakage
Reducing the weight of the tires reduces rotating mass because there is more (wheelset) rotating mass accelerating more responsively, which improves handling and climbing speed.
Long-lasting and stable tire pressure, resistant to high and low temperatures, stable tire pressure ensures safety when going downhill
Bicycle inner tube weighs only 38g, reducing the burden on the bike and making the ride lighter
This 28-inch 700C road inner tube is compatible with multiple tire sizes: 18/23/25/28, 30/32c
Description
Inner tube assembly steps
1. Put the inner tube into the tire sequentially, starting from the valve
2. When the inner tube is closed, adjust it to both sides in order and put it into the outer tube
3. Start from the corresponding side of the air valve of the inner tube and close the outer tire to both sides in order
4. If there is no downward adjustment and then pull back, the inner tube may be deformed or damaged when inflated
