A clever piece of design but expensive and a bit bulky to carry around in a jersey pocket. And the short stroke and awkward hose design make the klic pump less efficient than you would expect.
Lots of functions
Quite heavy and bulky
Short stroke for its size
Not very comfortable to use
Not intuitive for a new user
Crankbrothers’ pump is a bit like a Chinese box where you keep finding things hidden away that you didn’t realise were there. If you lent it to someone unexplained, chances are they wouldn’t work out how to use it.
On the face of it, it’s a straightforward pump with a handle which folds out to a 'T' at right angles to the pump body, providing a better grip and making pumping more comfortable. The handle clips solidly to the barrel when the pump’s not in use. It’s got a wide plunger, although the fit isn’t all that close, resulting in a bit of wobble at full extension.
At the bottom end of the barrel is a rotating sleeve which opens to reveal a cavity with a recessed nozzle that doesn’t fit any valve type. But what it does fit, using a magnet, is the pump’s hose. The hose itself is hidden away in the plunger. When you twist the handle into its open position it can be pulled out, then attached to the nozzle.

Despite just using magnets, the hose’s attachment to the pump is secure and not prone to blowing or falling off in use, although you can unseat it if you pull too much on the hose.
The hose includes an in-line pressure gauge calibrated in both psi and bar that's reasonably easy to use with a bright-blue pressure indicator. And at its tip is a reversible Presta/Schrader adaptor that screws onto the tyre’s valve.
Finally, under the screw-off silver cap at the end of the pump’s handle is a slide-out Presta-only CO2 inflator. This presses onto the tyre valve and takes a threaded CO2 cartridge. It’s handy for quick inflation when out on the road. Being plastic, it also gives you a bit of insulation when you use it.
Watch: How to set the perfect tyre pressure
The klic pump is quite a bulky piece and at 16cm long will outstretch a jersey pocket. Being on the heavy side it’s prone to bouncing around too. Despite its length, the stroke is quite short – around 12.5cm – so it takes quite a bit of work to get a tyre up to a reasonable pressure, let alone to the quoted 130psi maximum.
I also found that it was awkward to use, as the in-line gauge means that the flexible part of the hose is quite short. I sometimes pinched my hands on the handle too – there’s a sharp edge to one side of the bottom edge.

The Crankbrothers pump is a clever bit of kit, though. It packs more functionality than most pumps into a neat-looking piece that is relatively muck-resistant and will impress your mates. As well as the high-pressure version, there’s a high-volume variant for fat-tyre enthusiasts. Crankbrothers backs both up with a five-year warranty.
