The reviewer discusses TPU inner tubes from AliExpress in general but does not specifically mention the CYCLAMI Ultralight Road MTB 29 Bike TPU Inner Tube Tire French Valve FV 45mm For Gravel 700C 32C 35C 37C 40C 47C Super Light. They state that TPU tubes are the lightest, strongest, and most packable insurance policy for flats, even with tubeless setups. They found a deal for approximately $10 per tube, or a kit with two tubes, tire levers, and a patch kit for $12. The tubes are available in all sizes for road, gravel, and mountain bikes and are small enough to leave in a repair kit.
