An old saying goes: what if you buy cheap, then you buy it twice. Just as it was with me. I had fooled myself at a discount store and there brought me a cheap pump. After six months, I could no longer pump the 8 bar at my Renner, because I constantly pumping hose flew around the nose. Now I have a pump that can be used without a condom exchange for all common valves. Pressure gauge in the field of view it can be done without problems over 8 bar. Times should be what, there are appropriate substitute material. But assure me other road racers that they partially already have over 20 years of the pump and have never needed a spare part.
