In our dedicated Test Center, every handlebar, stem, and seat post undergoes extreme long‑term testing — both individually and in combination. Beyond standard European requirements, we apply our own ergotec SAFETY LEVEL criteria, which are significantly stricter than DIN EN ISO 4210 and DIN EN 17404. This ensures that every product not only meets but exceeds international safety standards, giving riders peace of mind on every journey. 3 Contact Points – The Optimal Connection Between Rider and Bike Cycling comfort and performance depend on three critical contact points: Handlebars & Grips Saddles & Seatposts Pedals ergotec offers a carefully coordinated product range across all three areas, allowing bikes to be tailored to the individual needs of each rider. This reduces discomfort, enhances ergonomics, and ensures that long distances can be covered with greater power, safety, and enjoyment. Safety Level All steering systems and all ergotec stems are tested without exception and are then classified with a SAFETY LEVEL. All ergotec seatposts also have a SAFETY LEVEL. Irrespective of whether you ride a mountain bike, an e-bike or a touring bike – you will always get the exact component with safety certification you need. ergotec SAFETY LEVEL is a safety classification for steering systems and seatposts on bicycles. ergotec products have a SAFETY LEVEL of 1 to 6. The higher the level, the greater the safety. Each level has their suggested bike activity, from city to cargo. All handlebars and stems are subjected to hard long-term testing individually and in combination. The same applies for seatposts. This testing is carried out in accordance with European testing standards or even higher demands. No other bike handlebar manufacturer in Europe has as large a testing centre as we do at ergotec. Furthermore, our products are tested frequently at recognised independent institutions.
