Quarq Tyrewiz 2.0 Air Pressure Sensor For Presta Valve (2 Sensors W/ Batteries, 2 Rubber Bumpers And A Rim Depth Guage):

Tires connect your bike to the road or trail. So, it’s no surprise that optimized tire pressure directly enhances your comfort, rolling resistance, and speed. TyreWiz 2.0 is redesigned for accuracy and greater compatibility for differing rim depths to provide precise pressure data in real-time for your best ride. Lightweight and durable, TyreWiz 2.0 utilizes LED lights to indicate when tire pressure is outside of the target range with an alert for low or high tire pressure. Running optimal tire pressure is a crucial factor in maximizing the speed and performance, especially on modern wheels. TyreWiz 2.0 allows you to make decisions affecting rolling resistance, traction, tire wear, and rider comfort. TyreWiz 2.0 also interfaces with the SRAM AXS app to provide personalized tire recommendations. With a universal rim adaptor and multiple valve lengths, the device sits flat on road or MTB rims. With the standard hand pump measuring at only +/-5% accuracy, TyreWiz 2.0 eliminates barriers by taking the guesswork out of tire pressure to make you faster.
