There are generally two big specialties for pumps. High Pressure (HP) or High Volume (HV). I ride Fat bikes, mountain bikes and road bikes, so I'm confused about buying a new pump to carry while on rides and whether I could find one pump to rule them all?
I know there are good pumps that do high pressure and others that do high volume. However, there are several that claim to be switchable between HP or HV.
How effective is this?
Will it be as effective as a dedicated HV pump on my fat bike tires? Will it also be able to put 110 lbs of pressure in my road bike tires as efficiently as a HP pump? Or are these a compromise that kind of works, but less than a purpose made HV or HP pump?
