SILCA Gravelero Mini Bike Pump high Volume GravelMountainRoad Alloy Body wHose and Locking Chuck Presta and Schrader Head Micro Hand Pump for tubedtubeless Tires Bike Hand Pump

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. Inverted Design: Gravelero like tattico is designed backwards from most pumps. The hose and valving is hidden inside the inner tube rather than the outer cylinder delivering up to 35% more air per stroke compared to pumps of similar length. Adaptable Cup Seal: Other pumps seal with o-rings which lose effectiveness as friction heat increases. The Gravelero Adaptable Cup Seal grows with the tube resulting in ultimate efficiency at all temperatures. Hidden Heat Sink: There is a heat sink hidden at the end of the barrel which absorbs a high percentage of heat generated when pumping. This keeps the rest of the pump cool, even at high pressures. Twin Tube Insulated Grip: Gravelero handle uses 2 thin tubes separated by an insulating air gap to keep hands cool. This results in better grip and control without risk to hands even when inflating multiple tires to high pressures.
