Sterling Pumps
Sterling is the new premium pump collection from crankbrothers. The high polished CNC and laser etched aluminum outer body results in a stunning proprietary design. A universal head works with both schrader or presta valves without adapting the head. To make them even easier to use, the sterling pumps feature a high/low volume function that allows you to adjust for high volume or high pressure. To top it off, the oversized gauge results in accurate pressure control and easy readability. There are four models of sterling pumps in two lengths (short or long), either with or without a gauge.

    Looks like the gage is on the wrong side? How can I pump and look at pressure if gage is on wrong side??

  • Roger says:

    Troy, turn your wheel so the stem is at the top, pointing down, instead of the bottom and the gauge will be on the right side to pump and watch pressure. ;)

    CB’s method of doing things differently is taking a turn to fashion, rather than engineering. I guess that’s one possible way to try and save CB’s ship from sinking.
