Reliable pump with top features. Very smooth, precise and stylish design. CNC-machined aluminium construction. Oversized piston and shaft integrated into an overall compact design. Reversible Presta/Schrader hose stows inside handle when not in use. Inflates to riding pressure quickly with 30% fewer strokes than conventional pumps. Comes equipped with the ABS Flex Hose and a Composite Matrix frame pump mount.
Air Bleed System (ABS): When using Presta valves, pressing the ABS button releases air back pressure in the pump hose making it easy to remove the Flex Hose from the valve. ABS eliminates the unthreading of removable Presta valve cores after inflation.
