The new special TPU material resists puncture. Thanks to the built-in manufacturing technology, there are no sewing marks around the inner tube, and a circle of interfaces around the inner tube air nozzle reduces the risk of trachoma in the inner tube.
The weight of the bicycle inner tube is only 36g, about 100g less than the traditional butyl rubber inner tube, and one pair saves 200g!
At the same time, the inertia of the outer ring of the wheel set is reduced, which makes the sprint and acceleration more sensitive.
