Abstract
There is disclosed a uniquely shaped bicycle chainstay structure produced using modern metal working methods, without the use of welding. The uniqueness of the structure allows a significant shortening of the chainstay length while increasing the tire and chain-ring clearances. An accomplishment not possible using prior art methods.
