Rene Herse TPU Tubes 700c/29"

Product description

Tubeless is great for many applications, but it comes with the hassle of having to top up sealant frequently. 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.

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.
