The RENNKOMPRESSOR is a part of the inventory at Kai Bartz’s bike shops for 25 years now. »I bought it in January 1992 from the company Hollmann in Dortmund (Germany)« he writes. Since then it has been used nearly every day. »The SKS Germany sales rep has supplied us with spare parts regularly so that the pump has worked at many races.« In addition, stickers of every kind on the steel tube make the RENNKOMPRESSOR very special – a personal design piece.
