The compact and lightweight SKS tire pressure sensor AIRSPY alleviates cyclists' worries about riding with insufficient air in their tires. Simply twist the valve adapter onto the valve, attach the sensor, and you're ready to go. Once installed, the dust- and water-resistant sensor continuously measures tire pressure. The precise real-time data is transmitted via Bluetooth or ANT+ to compatible bike computers or smartphones using the SKS Mybike app. In the app, you can view not only the current air pressure but also the temperature and battery status of the sensor. In case of pressure deviations, the discreet air spy alerts you with an alarm. Another practical feature: the AIRSPY can also be used as a portable digital manometer. This allows you to measure tire pressure digitally every time you inflate. It couldn't be easier. The Airspy is available as a set for the front and rear wheels. It is suitable for all AV/SV and most Dunlop valves, as well as for tubeless tires. Includes CR2032 button cell and theft protection brackets in various lengths. Contents: 2 x SKS Airspy tire pressure sensors (front and rear), 2 x SKS valve heads, 4 x SKS theft protection strips, 1 x CR2032 battery.
