Crankbrothers’ Sterling Pump is their premium pump and features highly-polished, CNC’d and laser-etched aluminum outer bodies. The Sterling’s universal head works with both schrader or presta valves (without you having to futz with the head’s internals). The sterling pump also features a high/low volume function that allows you to adjust for high volume or high pressure (in other words, mountain or road tire). Finally, the pump’s oversized gauge helps you keep track of your psi and is easy to read.
