I bought this pump for my cross bike. The pump has a gauge that lets you know how much you are pumping and the pump tube comes with an adapter for most types of valves, i.e. Presta, Schrader, and Dunlop (?). At first it was a bit confusing to know if I was doing it right or not but after a few tries it seems to be pumping air into the tyres well. It's super simple and really easy to use. On top of that the cost of buying it on Amazon is pretty good value if you compare getting one from the retail shops. For beginners to the cycling world, I think getting this item won't break the bank and will just do the job just as well as any other pump.. let's face it, not many of us are at the level of Lance Armstrong :)
