Velo News' pump test showed the Swedish Quicker Pro to be the hands down winner. In that test it reached 100psi in 100 strokes while the next best pump took 200 and the other 18 models required 300-500 strokes. It also pumps enough volume to work well with mountain bike tires. So this is a mini-pump that compares favorably even to full sized pumps. It's well made, will fit in a Velo Orange saddle bag or jersey pocket, and actually works well on both presta and schrader valves. We recently received the following e-mail: "Chris, this pump is so good that I feel no need to carry CO2 cartridges anymore. (You probably don't want to put that in the endorsement.) My procedure has been to pump the tire up as far as I could, then give it some CO2 blasts to fill it up. I'm 68 years old and don't have sufficient arm strength to use most mini pumps." The following is condensed from Quicker's description: Everyone who has tried to inflate 5 bars of pressure or more with a mini-pump, knows that it is in most cases even impossible! Quicker Pro has a pump design called Multi-Chamber Double Action. Unlike all other hand pumps on the market, Quicker Pro produces a constant airflow! Meaning that Quicker Pro generate the same air-volume per stroke independently what pressure you have in the tyre! So if you, for example pump, from 2-3 bars or from 9-10 bars the number of strokes will be the same! The pressure can be read at the integrated pressure gauge, which is cleverly placed in the front cylinder of the pump. Quicker Pro is very popular among road bikers since they require very high pressure in the tyres. Quicker Pro features a valve lock that fixes the pump to the valve and prevents leakage. The valve/nipple seal can easily be unscrewed and in order to change the valve just turn the inner parts. An important factor when it comes to pumping, is how much arm power you need to use! The force used when inflating with Quicker Pro is by 7 bars only 5 kilos/11 lb.! Compare this with a conventional pump which requires 17-20 kilos /37-44 lb.! A clip is included in case you would like to attach the Quicker Pro to your bike.
