Removing a direct-mount pump head from a Presta valve risks bending the stem or unscrewing the valve core, especially when pumping to high pressure and everything's hot. The Road Drive from Lezyne uses a flex hose that threads onto the valve at one end and connects to the pump body at the other, separating the pumping force from the valve connection. The hose stores inside the overlapping handle when not in use, screws out from one end, then threads onto the opposite end of the pump to extend the stroke length.

The CNC-machined aluminum construction runs the full length of the pump barrel, piston, and handle. The overlapping handle design compacts down to 194mm for storage but extends to provide a longer stroke when pumping. This delivers more air volume per stroke than a fixed-length pump of the same size, reducing the total number of strokes needed to reach road tire pressures. The pump hits 160 PSI maximum, though reaching pressures above 100 PSI requires significant arm strength.

The ABS Flex Hose has two connection ends: one side threads onto Presta valves for a secure connection, while the other side uses a slip-fit design as a backup option. The threaded connection holds firm under pressure surges and prevents the valve core loosening that can occur with direct-mount heads. The hose includes an integrated valve core tool for tubeless setups that require core removal. The ABS bleed button releases pressure from the hose before disconnecting, which closes the Presta valve and prevents air loss during pump removal.... Read More
