Minis Are Mighty! - Not all pumps fit all frames. If you're not sure what to get, ride your bike in so we can take a look and recommend one. Usually, mini pumps fit best because they come with a bracket that attaches to the bottle-cage screws. Once this bracket is installed, you just snap the pump into it to hold it securely (sometimes there's a little Velcro strap to help keep the pump in place). Or, you might prefer to carry your mini in your hydration pack, backpack or even your jersey pocket (this can get uncomfortable on long rides).
