The 2017 Giyo GF-71HV is a floor pump. This variation on the stalwart 71 is modified to produce larger air volume per stroke, sacrificing the 71's 180 psi upper limit in exchange for a much more efficient fill for fat mountain bike tires. The HV's upper limit is still a respectable 120 psi, and it won't take anywhere as long to get there. Construction is up to Giya's usual standards: a steel handle, aluminum barrel, and a steel base padded for unshod inflation comfort. Includes the Clever valve, able to inflate Presta, Schrader and Dunlop with authority.
A very good floor pump.
