TPU tubes take the performance of your tires to the next level.

TPU stands for thermoplastic polyurethane, a material that is far stronger than butyl, the black rubber traditionally used for tubes. That makes TPU an ideal material for bicycle tubes. TPU tubes have many advantages:
Lighter than butyl and latex tubes; lighter than tubeless sealant
Faster than butyl tubes or tubeless; as fast as latex tubes
More puncture-resistant than butyl or latex tubes
As airtight as butyl tubes.
Packs very small—ideal as a backup for tubeless tires
However, most TPU tubes use plastic valve stems, and the plastic deforms when the (metal) valve core in screwed in. Then the tube leaks, not because the material is porous, but because the valve doesn’t seal. Rene Herse TPU tubes use an all-metal valve with patented technology for leak-free performance.
Rene Herse TPU tubes are superlight, but not excessively so. Rather than pushing the tubes to the absolute limit, we’ve increased the wall thickness a little bit to increase the resistance to punctures and pinch flats—and also to make installation easier, especially with tubeless rims. Rene Herse TPU tubes have proven themselves in challenging events like Unbound XL, the 350-mile race across the Flint Hills of Kansas. They are suitable for disc and rim brakes.
Presta valve, 50 mm (polished) or 70 mm (black). Smooth valve stems make it easier to attach and remove press-on pump heads.
