»In your collection the REAL RennRADkompressor should not be missing«, writes Andreas Zipprich from Munich and sends us aerial greetings. Even on the pit stop, Andreas Zipprich is as a cyclist completely in his element. »I “drive” the RennRADkompressor for 25 years now«, he writes,»So it celebrates his personal anniversary with me.« There only remains for us to say: Congratulations!
