Mini pumps

I've used one of these & it really does work well

Agreed, that it looks really handy, but I spoke to some shop staff about it, and they said it does work exactly as advertised - though its slow in operation. The technology behind it is brilliant though.

For those that don't know this item; it works by pulling the handle/cord OUT, and on the inward rewind stroke, it generates power to pump air out. No pushing involved.

I also have a spare Cyclaire, liked the idea of this, but to be honest never got on with it, so it now just sits in my desk at work in case of dire emergency. So happy to accept offers or a swap for a Lezyne Pen Gauge for this as well. Pm me if interested.
