Quarq TyreWiz Wireless Bicycle Tire Sensor

Quarq, SRAM’s data and digital technology brand, today announced the launch of TyreWiz, the first-of-its-kind tire pressure sensor for road and mountain bike riders. The real-time monitoring device – designed to help riders reduce tire wear, improve compliance, and boost speed – is being debuted at Sea Otter this week and will be available on June 1 exclusively on Quarq.com. The two-sensor package will retail for $199.

The Quarq TyreWiz adds only 10 grams to your wheel weight and connects to your smartphone providing up to date tire pressure.

“Tire choice and tire pressure are the most underrated factors in cycling performance and comfort today,” said Jim Meyer, founder of Quarq. “Riders have more choices than ever when it comes to tire and rim design. There’s a challenge in finding the right combination of those things, and we’re making those choices based on gauge technology that hasn’t changed much since the 19th century. Real-time tire pressure monitoring technology isn’t new, and we believe it should be on every bicycle to make the riding experience better.”

Once installed, TyreWiz relays tire pressure data to a cycling computer or a smartphone every second. The TyreWiz app provides personalized recommendations and pressure alerts. For the first time, riders will have the ability to use highly accurate real-time information to make decisions that can affect rolling resistance, traction, tire wear, and rider comfort.

TyreWiz is durable, waterproof, powered by a long-lasting user-replaceable coin cell battery, and adds just 10 grams. The unit is compatible with removable Presta core valves in tube or tubeless tires, including those with sealant.

Quarq says they have designed TyreWiz to the same standards as its market-leading Dzero power meters, suspension tuning device ShockWiz and Qollector data acquisition system in Spearfish, South Dakota.
