A compact, lightweight hand pump with an
efficient, overlapping Composite Matrix handle, the HP Drive features a
CNC-machined aluminium barrel and piston and is optimised for
high-pressure applications. It’s quipped with our ABS Flex hose which is
both Presta and Schrader valve compatible.
Lezyne offers both a HP and HV version of every bike pump for both road and mountain bikes.
HP stands for High Pressure: Road bike tyres are
thin, low volume, and require higher pressures to run well (anywhere
between 90 and 160 PSI). Their HP pumps are designed to make it easier
to pump up road bike tyres to those pressures by using smaller pump
barrels.
HV stands for High Volume: Most mountain bike tyres
these days are run between 2.0" and 3.0" wide. Requiring so much air to
fill up these tyres, they developed the HV pumps with bigger pump
barrels to push more air into the tyres, making inflation of mountain
bike tyres faster and easier.
