Topeak Pressure-Right Pump Topeak pressure right Chuck Sv

When it works it is ok, but it only seems to work smoothly for certain valves. For others it is a faf to screw on to the valve and then it either closes the valve, or leaks air while you add pressure. ..

It works as described.

It took a moment to figure it out - one way valve - but it works great and removes the hassle of getting my bike tire inflated.

Screws on nice and easy, didn't remove the valve stem, and allowed me to air up my disk solo. Exactly what I wanted. It is pretty small so the needle bounced around on the pump, but that's a minor detail.
