Going all the way back to Cancellara's 2010 Paris-Roubaix victory, WorldTour a select few WorldTour mechanics have kept a secret. Hyper accurate pressure gauges hand built by Josh allowing them to guarantee the most accurate and repeatable tire pressures for the world's most demanding events. These coveted gauges have been used in more than 100 WorldTour victories including another five Paris-Roubaix wins. This gauge is known to all as 'THE TRUTH' and SILCA is thrilled to bring it to market for all and not just a select few WorldTour mechanics. Each TRUTH starts 100% USA made digital pressure gauge. These gauges are are temperature and humidity compensating using only the finest medical grade 316L stainless steel wetted components and sensors for a lifetime of trouble free use. The gauges use a custom sensor calibration, where each gauge is calibrated to perfect accuracy at 30.000psi, guaranteeing 0.2% accuracy between 0 and 60psi with accuracy drifting to 0.5% at 100 and 1% at 200psi. This sensor curve fit is unique amongst digital gauges, all of which have slightly non-linear behavior over their full scale reading. By calibrating to 30psi instead of 0psi, we are able to produce much higher accuracies at low pressures than traditional designs. Each TRUTH is further fitted with 6AL/4V 3D printed titanium body and aluminum twist style bleed valve capable of bleeding air as slow as 0.1 psi per minute. 3D printing also allows the internal air passage to be only 0.5mm diameter for minimal air required to activate the pressure sensor. As a result, the TRUTH only loses 0.1 psi per reading in a 25mm tire at 100 psi compared to as much as 5 psi per reading in other designs. The TRUTH is encased in a molded high-impact silicone rubber housing and uses a single 9V battery. Gauge has auto shutoff after 20 minutes and 1200 hour battery life. Temperature range 0 to 120°F (-1 to 49°C).
