Most of our concepts are formed on the trails and later end up in our product management and at our R&D teams. Careful construction with modern 3D-CAD programs are the foundation of our product development. In the next step, valuable insights are gained by FEM analysis with a consideration of the forces being at work. After computer tests, we are back on the trails. The prototypes have to withstand an in-depth field test. At the same time, we perform complex endurance tests at our in-house test station. This way, we find out if theory and practice match and if we can start batch production. With a 3D printer, the first shapes can be developed and tested for their efficiency. From the CAD design to the finished product, anything is created and monitored in-house. Modern inspection and measurement technologies are crucial to guarantee that our angular contact ball-bearings run smooth and steady, can be pressed in with the right amount of strength and fit perfectly into their seat. All of this comes down to tenths and hundredths. Last but not least the surface has to meet our expectations so that a good and even result is achieved by anodising. Only parts that are 100% perfect end up in our assembly.
The best material for each part is already determined in the development process and has to be purchased, tested and prepared. Then, the time has come to lathe, mill and saw. Of course, we only use premium tools and modern machines and our trained professionals make sure that our products are manufactured precisely — they are the foundation of our high standards. Our in-house production in Renningen allows us to react quickly to market needs and offers us the opportunity to easily put new ideas into action. Stickers would definitely be cheaper but would not meet our quality standard. For that reason, the label and the ACROS logo are lasered onto any hub — all of that happens in-house. At the end of the manufacturing process, the final assembly is made by hand. Each and every hub gets the attention it deserves. After the final inspection, all hubs are packaged and ready to be installed on your bike.
