I have the SNIPPTEC system installed on my bike and used it, for example, during a training tour of the USA. The technology has significantly reduced the rolling resistance, thus reducing the amount of physical effort I have to spend – certainly not an unimportant factor, considering that each of my tours covers several thousand kilometers. The frame of the bike is more stable, which results in an improved driving experience. My overall conclusion: I was completely satisfied and have no hesitation recommending the system. www.heukemes.net
