The Silca TRUTH Pressure Gauge, originally hand-built by Josh Poertner himself, lives up to its name by giving highly accurate and repeatable pressure readings. That's because this USA-made digital gauge not only compensates for temperature and humidity, but also eliminates the parallax error common to analogue readings. Its four-digit display and calibration to 30 psi lead to a guaranteed accuracy of 0.2% at 0-60 psi and 0.5% at 100 psi.Featuring a 3D printed titanium body, a medical grade stainless steel connection, a protective silicone rubber housing and a valve connection port that uses a Silca 252 Chuck, the TRUTH Gauge requires minimal air to activate and only loses 0.1 psi per reading in a 25mm tyre at 100 psi, making it far more efficient than competitor designs.Run on a 9V battery that gives an impressive 1,200 hours of battery life, the easy-to-use gauge has proven its stripes with more than a 100 WorldTour Victories and five Paris Roubaix wins since 2010, making it a must-have for serious racers and casual riders alike.Key features:Digital pressure gauge,Precise +/- 1% full scale accuracy at 200 psi,Compensates for temperature and humidity,Connection made from 316L stainless steel,6AL/4V 3D printed titanium body and airway,Aluminium twist-style bleed valve,High impact silicone rubber protective housing,Auto shut-off after 20 minutes, 1,200-hour battery life,9V battery included but not connected,Weight 221g,Presta compatible only,Made in the USA.
