‘unpuncturable’ inner tube

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

‘unpuncturable’ inner tube

Tubolito has released a thermoplastic polyurethane (TPU) inner tube called the X_Tubo City/Tour that comes with a one year warranty against flats. If it punctures within that period you get a free replacement.

They must have a limit.

I'm wondering about rolling resistance, too. That said, they're only making these for 30-50mm tires, so maybe they're not aimed at the performance road segment for a reason.

The Schwalbe Aerothan tubes are made with the same material as the Tubolitos. Don't think they have a no-flat warranty. They supposedly have rolling resistance similar to latex tubes but with better puncture protection. Have had mine for 3 weeks. No flats so far.
