No matter which component system or bike you use: the perfect chain ensures smooth cycling. And this is our motivation. We combine more than 120 years of bike expertise with the experience and engineering of an international chain manufacturer. We produce all our chains from the highest-grade steels in state-of-the-art production facilities. And before launching any new model, the chains must first withstand the highest loads in our testing plants, and be thoroughly tested, right down to every last rivet and pin, by experienced pro cyclists in extensive test runs in everyday scenarios and under racing conditions. Our chains. With passion for bikes. Since 1893.
