Anyone who has ever used one knows that mini bicycle pumps are generally pretty weak. It takes hundreds of strokes to fill a tire and is a pretty tiring process. That’s not the case with the EDC Bicycle Pump. It has a volume of 100cc and weighs just 160g. Plus it has the highest volume to weight ratio you can buy. It also packs in an integrated CO2 Inflator. It’s designed to work with One’s compact EDC Tool System.Other features include fully sealed weatherproof internals and it is made of 6061-T6 aluminum for durability. This is a pump you want with you.
