Product Information
Full details
The Crank Brothers Sterling Mini Pump is an essential tool for road and mountain cyclists who prioritize a balance between portability and inflation efficiency. This compact, CNC-machined aluminum pump excels at delivering quick pressure to both Schrader and Presta valves, making it a versatile companion for mid-ride flats; however, the manual nature of mini-pumps means it requires consistent effort to reach very high pressures compared to a floor pump.

Troubleshooting
Pump is leaking air at the valve
Ensure the head is pushed all the way onto the valve stem and the locking lever is fully engaged.
Pumping feels extremely difficult
Check that the pump is set to High-Pressure mode if the tire is already partially inflated.
Gauge is not moving
Verify that the valve core is open (Presta) and that the head is properly sealed against the valve.

Setup, Compatibility & Care
The pump is essentially "plug-and-play" right out of the box due to its universal valve head. To use it, simply press the head firmly onto your tire's valve stem and lock it into place. For maintenance, keep the internal seal clean by occasionally wiping the exterior of the pump body. If the pumping action becomes sticky, a light application of silicone-based lubricant to the internal shaft can restore smooth operation. Ensure the pump is stored in a dry environment to prevent debris from entering the valve head.
