Great pump
This is a great pump. I've had the unfortunate opportunity to fix many flats on the side of the road, and I've used a variety of different pumps, including a small pocket pump, a frame pump, and the Topeak Master Blaster Morph Road G pump. The main benefit if the pocket pump is its small size and light weight. It can easily fit into a jersey pocket and is light enough that it can often go unnoticed. There is a possibility however that, in the event of a crash, that the pump could do some damage to you as it is a hard object poised against your body. For that reason I often prefer to mount the pump on the bicycle. This has the dual benefit of freeing up space in my jersey pockets (which can often become cluttered with wallet, cell phone, etc) and ensuring that I always have a pump with me. The frame pump is the next obvious choice as it can be mounted semi-permanently. While the frame pump does enjoy fast filling times due to it's larger stroke volume, it can be difficult to negotiate holding the pump head and the valve stem while pumping.; The Topeak with its flexible hose alleviates this problem and allows good ergonomics while pumping.
