Dennis Glas, Team Leader Customer Service

“Our goal is to support every customer and retailer in the best way possible and we do our best to achieve this every day. Our passion is your satisfaction.”


Consistent and determined: SIGMA applies almost 40 years of experience in research and development not only to its products, but also to its customer service. The passion for sport and exercise, the input of professional athletes and, last but not least, the lively cooperation with dealers and customers are decisive driving forces. Proven diligence and an always friendly, professional approach to customer enquiries are a matter of course for us. They guarantee our worldwide success. And it is precisely these values that our customer service embodies anew every day.

Our customer service consists of a young and dedicated team that handles all customer enquiries at our headquarters in Neustadt an der Weinstraße – these questions come not only from Germany, but from numerous countries around the world. Many colleagues in our service team have combined their hobby with their job: They spend hours every week on their bikes, in their running shoes, and in nature. Our passion for both sport and technology allows us to offer you the best possible service.
