The GRAVELERO mini-pump builds from the same hose, chuck, and plunger design of our multi-award winning Tattico pump, in a package that pushes 35% more air from the same overall length. The design has been further refined for gravel and off-road use with a smooth outer texture and improved sealing to reject dirt and mud while also making for easy cleaning.Key Features:Light-weight, aluminum handle and barrelRetractable hoseThumb-lock, reversible chuck:Schrader or Presta80 psi9.5 inch / 243mm length139 gramsIncludes direct-mount bracketWith retaining strap
