Abstract

In the realm of competitive downhill mountain biking, there is a need for advancement of the drive train. The conventional sprocket, chain, and derailleur drive train is not well suited for the high speeds, impacts, and harsh environmental conditions inherrant to the sport of downhill racing. The gearbox created in this project replaces conventional drive trains on downhill mountain bikes. The initial design and proof of concept were designed to provide a comparable gear range and capabilities of a conventional drive train, while providing increased protection, strength, durability, and performance. The scope of the project was to provide a working prototype capable of demonstrating the ability of the gearbox to provide the overall system gear ratio range of 2.1-3.3 when interfaced with industry standard components, as well as a detailed design of a complete prototype system.
