Over 4 years of development, we built 6 prototypes, tried 10 conceptual mechanical principles in different parts of the device and created a unique solution with 4 ways to adjust your shifting experience. The Y-axis (Forward – Backward) and X-axis (Left – Right) springs are pushed by mechanisms that adjust spring compression to create unique tension chart. The Y-axis has 2 separate modulators to create at least 3 tension types of shifting (Y1, Y2, Y1+Y2) Shifting to Reverse and 7th speed is performed under additional pressure. Adjustments: – Y-axis tension – X-axis tension – Y-axis progression types: Sharp, Smooth – Knob installation height: 180–400mm
