We would not like to keep back the following story of Helmut Mauer (bike shop owner from Germany) from our RENNKOMPRESSOR-Fans:

“I am 25 years old, slim, Bordeaux and ventilate road bike tyres up to 8 bar every day. On tube tyres I even can do more bars if needed. Lately, I even was abused for the tyres of a fatbike! In doing so, I became quite warm…. I had to go to hospital twice to renew my rubber seals and the upper end cap. But after that I were completely under pressure again. If I am treat that well furthermore, I will become 100 years!”
