This mini pump makes most others look positively porky. It’s just 20cm long and 2cm in diameter, and ours weighed in at just 37g – lighter even than SKS’s claimed 39g. It's very easy to carry around, but it's not capable of the pressure SKS claims and it's time-consuming to use.
The design is about as basic as it gets, with no thumb-lock lever to secure the head on the valve – which must be Presta rather than Schrader – so you just push it into place and hold it there with your ﬁngers.
The small barrel means inﬂation is a slow process – you have to be pretty darn patient. Although we got enough air into the tube to get us home after a ﬂat, we never came close to the 140psi that the manufacturer reckons this pump is capable of.
We’d rather go for something that packs more of a punch, even if it’s considerably heavier. It does come with a handy rubber frame-mount to strap it to your bike, though.
