Silca Impero Ultimate II Frame Pump Large 54-59cm

From BikeTiresDirect

Silca's Impero Ultimate Frame Pump revamps the famous original using an aluminum construction and the finest component materials. The alloy barrel and head house an aluminum handle piston and rod that push on Silca's renowned leather washer made in Milan. All that air makes its way through a brass check valve that is similar to that used in their floor pump and then through a synthetic elastomer gasket that uses a 2-stage sealing design that holds onto valves without requiring a locking lever. Silca has made their name by producing pumps that work well along with looking good so it only takes 112 pumps on the size small to get a 23 mm road tire up to 100 psi.
