SKS Sub 40 | $49.99
BikeRadar verdict
"Small and light but we couldn't get high pressure from it"
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.
