Pack light with the iPump Micro Bike Air Pump. I’ve always resisted packing air pumps due their odd size and weight but did opt for those CO2 cartridges which weren’t much better due to their limited usage. The iPump will be finding a home in my pack as it only weighs 21 grams and is just over 5 inches long. This micro pump is also super strong as it’s constructed with a carbon fiber housing and a flexible nylon sliding hose that supports up to 150 psi. The iPump supports both Presta, Schrader and Dunlop valves. Support the iPump Kickstarter campaign and preorder your’s here.
