The compact and lightweight SKS tire pressure sensor Airspy takes away the worry for cyclists about having too little air in their tires. Simply screw the valve adapter onto the valve, attach the sensor, and you're ready to go. Once installed, the dust- and waterproof sensor continuously measures the 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, in addition to the current air pressure, the temperature and battery level of the sensor are displayed. 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 the tire pressure to be measured 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 a 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 batteries.
