Add too much in the way of accessories to your bike and you’ll end up looking like one of those guys who transports his weekly haul to the market by way of bike-back. In an effort to trim down and sleek up your ride, a couple of things seem to be on the chopping block and a couple of things are obvious necessities. A bike pump would appear to be one of the latter. With The Missing Link, that might change. If you do most of your riding in urban environments or places where there happen to be lots of gas stations, simply use this keychain adapter to inflate your tubes with an air compressor. Obviously needing one depends on the valve type your ride has, but it sure would be nice to ditch that hand pump attached to our frame.
