+1 on always using the Schrader tip adapter. Also always carry one on the bike with you if something happens just about anyone's pump will fit a Schrader but not every frame pump someone carries with fit a Presta. I throw an adapter in my underseat tool bag and then any pump will fit it. Yes I learned this the hard way when I was a newbie and a guy told me I was low on air but his pump didn't fit a presta.
