Zipp Smart Tube - AXS bikebox promotes even distribution of riderThe Smart Tube from ZIPP is specially developed for wheels with AXS tire pressure sensors. The special tube made of thermoplastic polyurethane (TPU) is required for proper use of the air pressure sensor. Conversely, the special design of the threaded valve does not allow mounting on other rims, as air would escape due to the sensor specific holes in the valve stem.
