Compared with ordinary butyl rubber inner tubes, the biggest advantage of TPU inner tubes is light weight. The standard version of inner tubes weighs about 35 grams, which is suitable for most riders who want to try something new.
TPU stands for thermoplastic polyurethane elastic material. The inner tube made of TPU is not only light in weight and has a good road feel, but also has a certain degree of puncture protection. At the same time, the TPU inner tube has heat resistance, and riders riding rim brake road bikes can also use it with confidence.
The TPU inner tube is made of the latest 100% environmentally friendly and recyclable materials in Germany. The elongation rate of the inner tube is 30% higher than that of other TPU inner tubes, which further improves the scratch resistance, friction resistance and puncture resistance of the inner tube.
.
The durability of this inner tube is good, and it has a certain anti-scratch and anti-puncture ability for small sharp objects, which can reduce the chance of tire blowout during daily riding.
The rubber of the inner tube air valve pad is designed with an R angle, which can effectively reduce the tire tube blowout caused by the friction between the tire tube and the rubber pad, making the air tightness of the inner tube more reliable.
Compared with ordinary inner tubes, TPU inner tubes have lower rolling resistance and feel close to tubeless tires, but most riders are more concerned about its price, weight and air tightness. The 35g regular version is a relatively safe choice. It is the most cost-effective for riders who have just replaced TPU inner tubes, while the 24g ultra-light version is suitable for riders who pursue the ultimate.
In terms of air tightness, due to the large individual differences in TPU inner tubes, one tire continues to be strong after being pumped to 90psi, and it still maintains the tire pressure that can be ridden after two weeks. Inflate once every four days. But in general, the airtight performance of the inner tube is satisfactory, and you may be able to find the perfect combination without inflating air for a week by trying a few more. Ensure that each finished tire has passed the inflation parking test before leaving the factory to ensure the air retention performance of each tire.
At present, domestic TPU inner tubes are highly competitive, and only with high quality and low price can they be favored by riders. In general, TPU inner tubes perform well in all aspects. If you are still using traditional butyl rubber inner tubes, these two TPU inner tubes are worth buying.
