FAQ
How to activate the AIRsistant on first use?
The AIRsistant sensor is shipped de-activated and must be activated to display the data on the compatible device. To activate the AIRsistant sensor, install it on the wheel and pump the tyre above 0.3 bar (4.35 psi). It may take up to 20 seconds for data to be shown on your display device. Once the data appears on the display the AIRsistant sensor is activated.
How are transmissions triggered from the AIRsistant?
Transmissions are triggered automatically by making a minimum of a quarter turn with your wheel. The AIRsistant sensor will also send transmissions during tyre inflation or deflation making pressure adjustments easy and providing a great alternative to tyre pressure measurement devices.
How are transmissions stopped from the AIRsistant?
The AIRsistant sensor will automatically stop transmitting if stationary for 120 seconds. The AIRsistant sensor will turn off automatically after 5 minutes of inactivity and automatically restart as soon as you move your bike again.
How is data transmitted from the AIRsistant to a display device?
Data is transmitted using Bluetooth Low Energy.
How can data from the AIRsistant be displayed?
Data from the AIRsistant sensor can be displayed using the iOS or Android AIRsistant smart device app. It is also possible to display the data from AIRsistant sensor on a compatible GARMIN device.
Can the AIRsistant smart device app be used alongside GARMIN devices?
The data measured from the AIRsistant sensor can be shown on compatible Garmin devices. However, only one display device is permitted at a time. Data from the AIRsistant sensor cannot be displayed in the AIRsistant smart device app and on a compatible Garmin device at the same time.
Is the AIRsistant compatible with all ANT devices?
No. The AIRsistant sensor transmits via Bluetooth to the AIRsistant smart device app and compatible GARMIN devices.
Why are the AIRsistant sensors not found or not displayed in the list when connecting to the AIRsistant smart device app?
Make sure the AIRsistant sensors are activated by rotating them for several seconds or via a tyre pressure change. The Bluetooth function on the phone must be switched on. For Android phones, the location function (GPS) must be activated when it is first connected. The AIRsistant smart device app should take care of both.
Can the AIRsistant also be used on tubeless wheels?
The AIRsistant sensor is compatible with tube and tubeless tyres.
For which tyre pressures can the AIRsistant be used?
The AIRsistant sensor can measure tyre pressure in the range of 0.0 to 8.3 bar (0 to 120 psi).
For which tyre diameters can AIRsistant be used?
The AIRsistant sensor is compatible with tyre diameters from 20” to 29”. Compatibility depends on the spoke distance for smaller diameters.
Can the AIRsistant be used with 3- or 4-wheel bikes?
Yes. 2-, 3- and 4-wheel bike profiles are available in the AIRsistant smart device app. AIRsistant sensors are available in dual or single packs.
Does the AIRsistant affect wheel balance?
No. The AIRsistant is compact and lightweight with only 21g per sensor.
Which valve types are compatible with the AIRsistant?
The AIRsistant sensor is compatible with Presta/ Sclaverand (SV) and Schrader/ Auto (AV) valves. Service kits are available in case you want to keep using your AIRsistant sensors but need to change the valve.
Can the AIRsistant be secured against theft?
AIRsistant sensors are designed to work exclusively with a smart device app/system developed by Schrader and authorized partners. The AIRsistant sensors are fitted and secured using the top locknut to prevent theft.
At what pressure does the AIRsistant raise a warning?
The pressure warning levels can be set and adjusted by the user depending on requirements. However, it is recommended to raise warning by +/-20% from desired placard. You can use the pressure calculator functionality in the AIRsistant smart device app for recommendations. The app issues a warning and marks the tyre in red when your tyre pressure goes below or above the pre-defined warning levels.
How accurate are the AIRsistant measurements?
The AIRsistant sensor measures very accurately with a pressure accuracy of +/-1% full scale and a resolution of 0.01 bar / 0.14 psi and a temperature accuracy of +/-3°C and resolution of 1°C.
How is the tyre inflated on which the AIRsistant is mounted?
You inflate your tyre the same way as you would usually do. The AIRsistant smart device app includes a digital tyre gauge function reflecting pressure changes on your display device, making pressure adjustments easy and providing a great alternative to tyre pressure measurement devices.
Does the AIRsistant battery require replacing?
No. The AIRsistant includes a lifetime battery up to 5000 operating hours. That makes AIRsistant a maintenance-free, fully sealed system optimal for off-road.
