This project aims to develop and produce an innovative 'non-geared' rear (traction) cube 'gear' system, competitive at a functional, productive (process) and cost level – as a superior alternative to the current benchmark (DT Swiss, Shimano, etc.). In connection with this, a user-friendly tool will be developed based on Excel + VBA that allows the efforts to be obtained in the critical sections of the cube (in the different parts) quickly, using as input different cycling conditions (model development) and geometric chain of transmission, transmission types, gear ratios, position of the bearings in relation to the power chain. To obtain this product, it will be necessary, among others, to carry out research and development of (standardized) models, of different cycling conditions (enduro, downhill, bmx, cyclocross, road, track, mountain, etc.), on how to define efforts (inputs), for product development base (hubs). The model of a production system (machine or composite process), at a competitive price, will also be created to produce the cubes, including the DT Swiss 18/24/36/54 SL ratchet system. A catalog will also be produced on Cycling for Sustainable Development.
