If you don’t ride on debris-strewn highway shoulders (where the sealant will seal small punctures from glass and steel wires) and if your tires are wide enough (so you don’t get pinch flats), tubes are a great choice. TPU tubes take the performance of your tires to the next level.\u003c\/p\u003e\n\u003cp\u003eTPU 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.

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.\u003c\/p\u003e\n\u003cp\u003eRene 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.\u003c\/p\u003e\n\u003cp\u003ePresta valve, 50 mm (polished) or 70 mm (black).
