In the world of competitive cycling every second counts. Every detail of the bike must be perfect if you want to take the win. Improper bike setup can cost several seconds on the track leaving you with 5th place instead of 1st. One aspect of racing that every elite level racer has a personal preference for is tire pressure. Many riders change the PSI of their tires every race. Every track has different obstacles and a different speed. Sometimes this change is within half of a PSI. Tire pressure is a balance between rolling speed, traction, and rim protection. Low tire pressure provides amazing traction while high tire pressure ensures high rolling speed and increased rim protection. Finding the happy medium is the challenge and that challenge changes track to track. The Quarq Tyrewiz Air Pressure Sensor is the world’s first “real-time” air pressure sensor. The Tyrewiz connects wirelessly to a phone or cycling computer giving you constant “real-time” data on your psi levels. LED lights on the gauge itself also indicate high or low-pressure ratings for quick visual confirmation. The Tyrewiz works with tube or tubeless tires and isn’t afraid of tubeless sealant either. The Wiz also provides personalized tire pressure recommendations to help you dial in your ride. For installation, just unthread the valve core out of your Presta valve and thread the Tyrewiz on.
