Mountain-bike adventurer Harald Philipp would have missed much if there was no Rennkompressor: Tours to the most unusual regions of Europe. Challenges on dangerous mountain and climbing paths. Expeditions to the wilderness. WE also have missed something if there was no Rennkompressor: Harald Philipp’s amazing film screenings which put his passion for mountainbiking into words. A Live-Show with goose bumps feeling.But, fortunately, the Rennkompressor takes care that Harald Philipp can go on adventures day by day and shares his knowledge with us: without Blow no Flow.
