However the frame fit pump is inconvenient. I sometimes forget to take it off when I park up, risking theft and occasionally I have forgotten to pick it up when leaving work, which would leave me unable to fix a puncture on the way home (and probably on the way back in the following day).
So I wanted something to fit in the pannier. The Topeak Road Morph is well received on the forum, I decided to get it's little brother. It came with a frame fit plastic clip (zip-tie or bolt to bottle cage mounts instead of a bottle cage) but I don't expect to use it. Internal gubbins in the head can be swapped around manually between Presta and Schraeder settings.
It certainly is little and deploys easily in the miniature track pump style.
It needed a test, rather than wait for the fairy I let the tyre down and pumped it up again.
The head was not the easiest to attach to the presta valve requiring quite a firm push to go on (this may just be lack of familiarity), the locking lever was effective. The small barrel can only deliver a little air at a time (the reality of all mini-pumps) but it certainly delivered these smoothly.
The studded tyres I was pumping have a 58PSI maximum which was the target I was aiming for and was achieved with ease in around 120 strokes, the HPX would have got there in around 60 strokes but it would have felt like harder work.
The packaging claims it can reach 160PSI. In practice as a get me home pump, it won't need to reach half that figure.
Small, effective and for £16.43 good value; ticks my boxes and inflates my tyres

I would have liked to have put this on my audax bike to use during the summer when I only have a small saddle pack on the bike and do want to use both bottle cages, the zip tie option being a bit rubbish in practice due to slipping and marking the frame paint.
