Mini pumps are great, but can be tiring on big volume tyres. And when you've got room in your pack, or are riding with a group, a bigger volume pump can make things easier. Or just keep it in the car.
The Rumbler works like a micro-floor pump. Dual piston action makes things inflate quicker. A 6063 alloy barrel is tough to protect against knocks, but won't weigh you down. The head of the pump uses a reversible tool-less design to swap between presta (skinny roadie) or schrader (fat car type) valves.
High volume high pressure is the outcome, with this until happy to up to 120psi. A great performer. Ideal in your travelling toolbox, or day pack. All this for an amazing price direct to you.
