Ultralight TPU Tube That Keeps a 20-Inch Ride Feeling Quick
This TPU inner tube is a lightweight upgrade for 20" x 2.1" setups, cutting rotating weight and packing down small for an easy spare. Compared to traditional rubber tubes, TPU construction is designed to be tougher in storage and more resistant to everyday punctures.
It’s built around a Presta valve with a removable core, and the valve base is sized to fit Schrader-drilled rims. For 20-inch wheels, this version is intended for the common 406 mm rim size used with wider 2.1–2.5 tires.
Compact. Clever. Essential.
