- CO2 is OK for topping up, but initial inflation with CO2 is not recommended. The high pressure and cold temperature (as the CO2 expands) can split the tubes.

- The Rene Herse TPU tubes are made in Germany. They are not just some rebranded product you can get from other sources. (None of our products are.)

Is it better to size up or down on TPU tubes for a tire that fits two size ranges? For example, 650x48
