What are the key differences between large floor pumps with different base types, such as a wide base or narrow base, and how do these differences impact the overall performance, stability, and durability of the pump? Does a wider base necessarily mean greater stability, or are there other factors at play? How do the materials used in the base construction affect the pumps ability to withstand heavy use and potential drops or impacts? Are there any specific scenarios or environments where one base type is preferable to another, such as in a home workshop versus a professional bike shop? Do the differences in base type have any effect on the pumps ability to accommodate different valve types or wheel sizes? Can a narrow base pump be just as effective and reliable as a wide base pump, or are there inherent limitations to its design? How do the weight and portability of the pump factor into the decision between a wide base and narrow base design? Are there any notable examples of floor pumps that have successfully utilized unconventional base designs or materials to achieve improved performance or functionality?
