Get’n a bunch of flats, and growing increasingly tired of all that road or trail side pumping after you install a new tube? If it’s any consolation you’re not alone. If conventional travel pumps are wearing you out join those of us who use air cartridges to do the inflating for us.
The Cannondale Airspeed Microfill pictured below is a great example of how compact and simple such a system can be. Just thread the chuck onto your valve stem, thread the cartridge into the chuck, and voila, your tube fills with air effortlessly.
For just $25 this system is as cheap or cheaper than the least expensive traditional travel pump on the market, and additional CO2 cartridges inexpensive and readily available.
