Lightweight, durable, and powered by a long-lasting user-replaceable coin cell battery, Quarq's TyreWiz monitors air pressure in real-time and relays the data to a cycling computer or a smartphone. The TyreWiz app uses that data to deliver personalized recommendations and pressure alerts. For the first time, riders have access to highly accurate real-time tire pressure data to make decisions that can affect rolling resistance, traction, tire wear, and rider comfort.
Features:
- Designed for road, mountain and gravel.
- Personalized tire pressure recommendations in the smartphone app for iOS and Android.
- NFC pairing for fast and easy connection by BLE to a phone.
- Data reported with +/- 2% accuracy at .1 PSI resolution.
- Broadly compatible with tires that use a removable Presta-style valve core.
- Inexpensive, user-replaceable CR1632 battery lasts for 300 hours.
- IPX7 dustproof/waterproof rating.
- Works with both tube and tubeless, and tires with anti-flat sealant.

Wish they were cheaper. Convenient and provide peace of mind
I bought these for a road tandem after having a flat tire just before a long fast descent and hearing of another tandem that crashed with serious injuries when they made a turn on a soft front tire. Being able to detect a flat early seems like a good idea.
These were easy to set up and pair with both my phone and Garmin. After setting the max and min pressure for each unit I can quickly spin the wheel before a ride to check if the tire is still above my minimum... green light is go, red light means get the pump out. They occasionally lose connection to the Garmin for a few seconds but have always come back.
The data field for the Garmin turns into inverse text (black background) when the pressure is out of range, so if a tire is losing air during a ride it will be easy to see on the screen. Having these has shown me that the tire pressure goes up several PSI when riding and that I really don't lose any pressure when removing the pump from the valve..
If they could get these things down to $50 a pair I'd have them on all my bikes. At $200 I can't see adding them to all the bikes in my rather large collection.
