SuperPista Digital combines the functional attributes of the SuperPista Ultimate Hiro with our latest pump platform complete a highly accurate, top-mounted digital pressure gauge. The performance components that are unique to a SILCA pump; proprietary leather washer, Brass air check valve assembly, and Hiro Side Lever Locking Presta Chuck; ensure that the precision, durability and rebuildabilty that you?ve come to expect from us remain. The body of SuperPista Digital is a custom alloy extrusion with a three-footed base made from thick cast alloy for increased stability. For the gauge, we chose to high mount it at the top of the pump tube for increased visibility of the digital gauge face. The gauge itself is backlit, with the ability to set pressure alerts and measure up to 220 PSI or 15.1 BAR. The system is powered by a standard CR2032 battery that?s pressure activated and conveniently housed directly under the gauge face. The pump?s hose is mounted to the side of the gauge plate and secured by a hook near the base of the pump with the chuck then secured by a magnetic chuck dock on the opposite side of the gauge plate. The chuck for SuperPista Digital is our top-tier Hiro Side Lever Locking Presta Chuck which simply threads into the Schrader chuck at the end of the hose. The Ash wood handle features the same ergonomic design of the SuperPista Ultimate Hiro edition and comes complete with a handle strap to secure it when not in use.
