We have in the family 6 bicycles (mountain bike, road bike, trekking, etc.) and almost always air has somewhere been missing. Mostly I pumped with the usual hand-pumps air forever without noticeably what has changed on the tire pressure. In the past I have therefore always pushed me to the tire inflating and am increasingly been driven almost to the rim.
Until I was able to test the SKS Rennkompressor with my neighbor. Because even I could (female / blond) easily inflate tires. Immediately I bought this pump and have since impressed. All our bikes have an exemplary tire pressure and if it now goes around the inflation, I argue with my sons who is allowed to use the Rennkompressor.
Super device! I am angry that I have not only discovered it earlier. The one or the other exit would have saved me with "soft" tires.
