When it comes to biking, knowing your tire pressure is extremely important as it can drastically impact how your bike handles on certain terrain. For fat bikes, the pressure is extremely low in the range of 8-12psi, so having a reliable gauge that can help you fine-tune your tire pressure is vital. The Topeak digital tire pressure gauge features a rotating SmartHead® and works seamlessly with Presta and Schrader valves without changing parts. Precision digital gauge reads up to 250 psi / 17 bar and is designed for use with tires, suspension forks and rear shock units. LCD display can be programmed to show pressure in psi, Bar, or kg/cm2.
