Blackburn Core 3 Floor Pump SIL bivo Elasticized arch brace for secureDetails PERFECT PRESSURE. EVERY RIDE. At nearly 28 inches tall, the Core 3 towers over most floor pumps. The 48 inch long hose is long enough to get air pressure to anywhere you could need it. Like the Pro, the Core 3 features our AirTap head that fits Schrader Presta Dunlop valves and has a pressure bleed button built in. We also integrated the easy to read, 3 inch gauge into the massive steel base of the Core 3 to help it have a rock solid stance.
