Query: Great little pump

Ive only pumped up my road bike 23cc tires a couple of times using this pump. As with all tiny hand pumps it gets semi hard to pump past 90 psi. The good thing is no matter how awkwardly I force this pump it doesn't seem to give out. Its very lightweight but sturdy at the same time. This pump also comes with an adapter that will screw onto your water bottle holder. The guage is OK but doesn't give you much of a gradient. Topeak makes great products, so I won't be surprised if this pump lasts me at least a couple of years.
