- Environmental protection :TPU (thermoplastic polyurethane elastomer material) inner tube is made of green and environmentally friendly thermoplastic polyurethane material, which can achieve 100% recyclable.
- Upgrade: TPU inner tubes are lighter and stronger than butyl rubber and have higher air tightness than latex. With a weight reduction of 70% compared to ordinary butyl rubber inner tube, the use of this TPU ultra-light inner tube can significantly reduce the rotational mass of the vehicle riding, making the ride more flexible, accelerating more agile, and bringing improved handling and climbing speed.
- Portable: The TPU inner tube is more than 50% smaller than the traditional inner tube when folded, and easy to carry, reducing the volume placed in the pocket (or car bag), freeing up valuable space to carry more supplies.
- The inner tube of environmentally friendly material is very good for the environmentally friendly outer tube and the colored outer tire, and will not pollute and affect the color of the outer tire.
- This product is an ultra-lightweight inner tube, which is ideal for enjoying short and easy rides.

Note: 1. Like other bicycle inner tubes, we do not recommend charging the TPU inner tube with too much air pressure without the tires and rims, resulting in irreversible damage to the inner tube. Because the thickness of the TPU inner tube is very thin (only 0.2-0.3mm), although it has higher strength and toughness than other rubber inner tubes, it is still impossible to avoid deformation in the case of empty beating (directly inflating the inner tube without assembly between the outer tire and the rim), so we recommend that when assembling the TPU inner tube, As long as the air pressure of 0.5-1.0PSI is first driven, the position between the inner tube and the outer tire and the rim is adjusted, and the inner tube is not broken and fully fitted, and then the air is pumped. 2. High temperature is the natural enemy of TPU (thermoplastic polyurethane elastomer material), in rare cases the rim brake will overheat the rim, reaching extremely high temperatures, resulting in potential safety issues, in order to ensure the complete safety of the rider, we recommend only using TPU inner tubes on bicycles equipped with disc brakes.
