SKS Puro Pump
6 10

SKS Puro Pro road pump's diminutive size will appeal to racers determined to shave every last gram from their bikes without forgoing a basic toolkit. However, while a tangible complement to Co2 inflators and with build quality to the brand's usual high standards; you'll need arms like Popeye and the patience of a saint to restore everyday 23mm training rubber from flaccid to 125, let alone 144psi as claimed.

Measuring 19.5cm and weighing a feathery 89g, (claimed weight is 80g) thanks to extensive use of high quality plastics (there's a carbon version too), the Puro feels reassuringly solid. To use it's simply a question of rotating the top cap clockwise so it aligns with the circle to free the barrel. SKS make efficient use of available space here too, employing a clear Perspex tube with pressure gauge in both bar and psi inscribed in black for easy reference against the orange. Twisting the handle when pressed close releases the nifty plated presta head ready for action. To retract simply press down using your thumb and lock the pump closed. The hinged carry bracket mounting to the frame's bottle boss is extremely well designed. Serrated closures allow a custom fit- loose for quick draws or pinched tight to prevent unwanted ejection over the pav.

These small details certainly count and perhaps I'm being harsh but common to the pint sized breed of mini pumps, performance is a relative term. Latching the head on to the valve requires care my second attempt claimed the first casualty, shearing the tip forty-two strokes in. Proceeding gingerly and assuming a smooth, rhythmic motion brings 25psi to a 25mm tyre in around 40 strokes/seconds. However, nudging past thirty-five psi things become an uphill struggle. 380 strokes and five minutes later I wheezed up to eighty Psi, biceps burning with lactic acid. Achieving a further twenty-five pretty much consumed my will to live - ours locked out at a commendable 110. The song remained much the same with common or garden 23mm training rubber save for an extra 10psi getting that up to a pretty impressive 120. Eventually.

Verdict

Well made but for emergencies only since reaching realistic road pressures without using a Co2 inflator as well is extremely difficult

Make and model: SKS Puro Pump

Size tested: Black

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

"Puro Road- cool outside, controlled power inside. With the Puro SKS has given free rein to their passion of high-pressure pumps, cleverly integrating everything: the valve connection and the pressure gauge. At the very first stroke, the eye is drawn to the integrated pressure gauge. Thanks to the integrated concept all parts of the pump are completely dirt protected. The Puro smoothly builds up the pressure until the scale approaches the 140 PSI mark". Great looking pump with some nice details and a smooth action but common to the type, realistic road pressures take some doing.

Tell us some more about the technical aspects of the product?

Tell us how the product performed overall when used for its designed purpose

Bijous dimensions, a smooth action, integral pressue gauge and nifty carry bracket are definite plus points but inflationary prowess is no match for traditional frame-fit types and care has to be taken to avoid bending/snapping presta valve ends.

Tell us what you particularly liked about the product

Sharp styling, smooth action and nice detailing.

Tell us what you particularly disliked about the product

Tendency for the head to damage presta valves and poor inflatory prowess.

Did you enjoy using the product? No

Would you consider buying the product? No

Would you recommend the product to a friend? Not unless they punctured infrequently and carried Co2 inflators

Overall rating: 5/10

If the tyre doesn't puncture you don't need the pump.

If the tyre punctures on a pleasant, sunny day and you've got time to sit peacefully by the side of a quiet lane and play with your tiny little pump for a while then that's alright.

But when the tyre punctures as the light fades at the end of a long, damp, lousy day and you're tired and knackered and want to go home there is much to be said for a pump that inflates tyres. It is worth carrying a little bit more weight as insurance against the tearful, shivering rage and frustration of those occasions I reckon.

This information is now old since the Puro is no longer made, but the one that I had failed miserably, on its first use it would not get past 45 psi and with a great deal of hand pressure when suddenly the pump blew out the top cap with the plunger going straight out of the body of the pump. Obviously I had to walk 5 miles home, fortunately I wasn't further out. And to even get to 45 psi I had put in about 350 strokes!

I thought it was just my pump but as a couple of years went by I started to hear similar issues with the Puro. Fortunately at the time SKS had great customer service and under warranty they replaced the pump with a much better pump called the Wese RaceDay Carbon, that one I still use today and like it a lot, not sure why SKS stopped making it.

Only positives about the Puro (mine was black) was that it looked fantastic, very light weight, automatically hid the air chuck inside the pump with just a twist, and the built in psi gauge was a stroke of genius, not sure why other pumps haven't built that barrel gauge. Other than that it was the worst pump I've ever owned.

Small pumps are a pain to use, and some minis have to be just for looks and not for use because I've had others I had to send back because they failed to reach 75 psi not even close to the advertised 160 PSI. And to get to 75 psi you're pushing a pump about 400 times with a great deal of effort especially past 45 psi. I've only found 2 mini pumps that can at least reach my PSI levels of 100 and 110 out of about a dozen I've tried, both of those pumps are longer than the others by at least an inch which is why they can reach the upper limits. Not sure if I can mention the other brands or not so I won't, but just look for longer mini pumps, and not those short small lightweight jobs if you want to actually put air in your tire.
