Inner tube made of TPU (thermoplastic polyurethane) material.
Durability has been improved by about 1.5 times even though it is about 70 % lighter than the normal butyl rubber inner tube.
Because the expansion rate is high, it is also a nice point that the width of the compatible tire size is wide.
Since the outer periphery of the wheel that affects handling and rowing becomes lighter, the cruise also steps on the cruising as if the bike appeared in front of the zero start.
It is a low rolling resistance, and it is an excellent item that has excellent cost effects that increase the driving performance of your car just by changing the tube.
