Never guess your tyre pressure again. The Quarq TyreWiz sensor pair screws directly onto your Presta valve stems and broadcasts real-time pressure data to your Garmin, Wahoo or any ANT+/Bluetooth-compatible head unit. This version is specifically fitted for Zipp 303 Firecrest Disc Brake wheels with 40mm rims.

  • Real-time PSI readout on your head unit or smartphone
  • Specific fit for Zipp 303 Firecrest Disc Brake 40mm rims — no shimming or adapters
  • Pack includes 2 sensors (front and rear), batteries pre-installed, and a valve core removal tool
  • ANT+ and Bluetooth Smart dual transmission
  • Pressure drop alerts for early puncture warning

TyreWiz attaches directly to the valve core, replacing it with the sensor unit. Installation takes under a minute per wheel. The sensor is weatherproof and designed to survive road spray, mud and washing. Accurate pressure readings help you fine-tune your setup for conditions — lower pressures for grip, higher for rolling efficiency.

Designed specifically for Zipp 303 Firecrest Disc Brake wheels with 40mm rim depth. Compatible with ANT+ and Bluetooth head units including Garmin and Wahoo devices.
