I have a bicycle pump with a "smart" head for both Presta and Schrader valves. Does ok with Presta, horrible with Schrader. It's hard to get the head attached to the stem and easy to push the valve stem back into the the rim when attempting to do so. Looking for a floor pump recommendation that does either Schrader only or has a dual head. Not ever used one but I'm assuming the Schrader head in a dual head will do better than what I have now. Doesn't have to be fancy, Only mainly used to top off pressure on one or two bikes. Another pro is that I don't like the pumps that you lift the head lever up as opposed to clicking down to lock to the stem but not a deal breaker if it easily attaches to a Schrader valve.
