When it comes to cycling gear, size is of utmost importance. The heavier the object, the less likely you'll want it in your pack. That's where the air pump dilemma comes into play. You need a pump, because flats happen. It's an unavoidable part of the road. But a pump that's lightweight, easy to use, and actually works is a hard trifecta to fulfill. Fortunately crankbrothers saw the problem, which is why they designed the Sterling SG, a short dual piston premium pump with a high pressure air switch and gauge. Small, simple, and reliable, this hand held gadget is the answer to all your inflating needs.
