Know your pressure. Your tyres are the only thing connecting you to the road or trail, and having optimal tyre pressure can have more impact on ride comfort than both frame and wheel choice combined. However, finding the right tyre pressure requires trial and error.

Tyrewiz is the first-of-its-kind tyre pressure sensor for riders of gravel bikes and road bikes, taking the guesswork out of finding that optimal tyre pressure. Lightweight and durable, tyrewiz adds only 10g to your tyres. With an ipx7 waterproof and dustproof rating, you can confidently ride on any type of trail and know that your tire pressure sensor will keep going strong.

Tyrewiz reports data with +/-2% accuracy at a resolution of .1 psi; vastly more accurate than any tyre pump on the market. Tyrewiz monitors air pressure in real-time and relays the data to a cycling computer or a smartphone. That information is relayed to the SRAM axs app and delivers personalized recommendations and pressure alerts.

Tyrewiz gives riders access to highly accurate real-time tyre pressure data to make decisions that can affect rolling resistance, traction, tire wear, and rider comfort.
