Rene Herse - TPU Tube 32 Inch

Rene Herse TPU tubes are now available in the 32″ / 686 mm size, perfect for the coming generation of mountain and gravel bikes. Run your tires with TPU tubes, or use them as spares for tubeless setups. The tubes fit tires from 45 to 68 mm (1.8″ – 2.6″) wide. 

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. 
• Pack very small—ideal as a backup for tubeless tires 

Rene Herse TPU tubes have patented all-metal valves. This eliminates the mysterious leaks that can occur with plastic valve stems—they tend to deform when the metal valve cores are screwed in. 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. Equipped with 70 mm threaded (black) valves. 

Pro Tip: Patching TPU tubes is much easier than patching butyl or latex tubes. Simply wipe the tube with an alcohol wipe (included in Rene Herse patch kit) and stick on a patch. There’s no need to roughen the tube with sandpaper.
