At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

With its CNC-machined aluminium body and subtle gold detailing, the Crank Brothers Power Pump Ultra is a sturdy and good looking mini pump. Despite the lack of a bottle cage bracket, it's very portable: at 175mm it's small enough for a jersey pocket. As with many tiny pumps, inflating a road tyre to a usable pressure requires the patience of a saint. It best suits cyclists who travel lightly, puncture rarely, and perhaps have a CO2 cartridge in reserve.

It feels remarkably solid thanks to its predominantly metal construction. The T-shaped plastic pump head has a presta fitting on one side and a Schrader on the other. Each locks onto the relevant valve, minimising air loss and the potential to damage the valve stem.

A dial at the base of the pump lets you switch between low pressure/high volume and high pressure/low volume pumping. The former setting pumps 5.6 cubic inches per stroke, the latter 2.2 cubic inches. So you can start off with high volume pumping, then switch to high pressure as pumping gets harder.

Crank Bros claim that the Power Pump Ultra will deliver a whopping 115psi. I set my sights a bit lower initially, and measured how many strokes and how much time it took to inflate a cross-section of tyres (ranging from 700x25 to 20x1.75) to a modest 40psi.

The tyres inflated at a snail's pace. The 700x25 took three and a half minutes and 178 strokes to reach 40psi. By way of comparison: a 700x38 tyre took four minutes and 207 strokes; a 26x1.6 six minutes and 306 strokes; and a 20x1.75 a mammoth eight minutes and 342 strokes!

Since 40psi isn't a practical pressure for most road tyres, I had a breather and then went in search of the advertised 115psi. After ten minutes and thirty seconds and 712 strokes, and thinking I was about to haemorrhage, I locked out at 108psi. That's not a bad headline figure but it isn't something I'd attempt again with relish or regularity.

If it doesn't pump much per stroke, at least the Power Pump Ultra does so reliably. Ready availability of spare parts means it can be rebuilt if necessary, and the lifetime warranty adds further peace of mind.

Verdict

A bijou designer pump for emergencies only, as it takes time and effort to reach high pressures
