The Pocket Drive Pro HV is an impressively compact and lightweight bicycle hand pump that, despite its small size, delivers high pumping performance for large-volume tires, such as those found on gravel and mountain bikes. It is made entirely from durable, CNC-machined aluminum and features a lightly knurled shaft for a slip-resistant operation. With its overlapping handle and integrated ABS flex hose, the Pocket Drive Pro HV offers unmatched performance for its size. The hose also includes a built-in valve core tool. The pump is compatible with both Presta and Schrader valves and can be completely overhauled for years of trouble-free use. Includes a high-quality composite matrix frame mount.
