GIYO MTB mini pump with gauge
Not the world’s most expensive mini pump but this little fellow packs a good punch. The stroke is around 21cm / 8″ so you can get a decent amount of air through it with each pump stroke, unlike some smaller versions. Only just over 8″ (22cm approx.) collapsed (16.5 ” / 40cm extended) and around 3.5 oz (99 grams) so it fits easily into your back pack or pocket in your jersey, unless you want to frame mount it.
The body and most parts are good quality aluminium alloy, with a plastic main handle. The schrader / presta head is the usual “unscrew the collar and reverse the collet inside” style fitting, and with an alloy lever clamp it attaches quickly and securely to the valve.
Another great feature is the built in gauge, which seems pretty accurate every time we have used it (around the 45 – 65 psi range) but is rated up to 100 psi – though as this is a compact pump it would need a bit of time to get up to that kind of pressure. That said, there’s definitely enough “oomph” though to easily re-inflate after a puncture and to be able to finish your ride.
For ease of use it is best to grasp the valve end with your left hand and also grip a fork leg or stanchion at the same time. This helps stabilises the valve end, and you can then get a good rhythm going with the pumping without stressing the valve stem too much – it only takes a minute or so to re-inflate a tubed MTB tyre once you get going.
A good little mini pump, with the added benefit of an accurate gauge.
