Modification of the crank store on a bicycle

In its first half this thesis describes most common materials used in the bicycle industry as well as various types and standards of bottom brackets and mentions their pros and cons. Starting with the oldest cotter pin type all the way to the most modern press fit bottom brackets. The major objective of the second part of this thesis is to design a crankset based on the research in the first half. One of the most important aspects of the design was to choose a suitable type of bottom bracket for non-competetive riding. Structural analysis using finite element method was done and the design was altered accordingly. In the end the process of manufacture was described
