Between the workshop and the salesroom of the bike shop „Radlager“ in Cologne-Nippes hangs a RENNKOMPRESSOR, so costumers and workers can use it all time when it´s needed. One day an unknown “Luftikus” garnished the background with a picture. To see on the picture: A man who tries to inflate a tire of a digger with a floor pump. If the picture is intended to be a motivation for everybody inflating a tire or if the unknown person by himself inflated the tire of the digger is unknown until today. But one thing is sure: With the RENNKOMPRESSOR the tire of the digger would have gotten back in shape, at least a bit.
