Abstract
The present patent application describes a modular crankset for bicycles. The described modular crankset is useful for users, since it solves issues related to the speed of replacement of elements, the easiness of the replacement procedures and lowers the weight of the set without compromising the consistency and rigidity of the set. The current technology is applicable to any bicycle available in the market, including electrical bicycles, and it is especially interesting for competition bicycles, wherein the replacement of the constituent elements of the crankset should be made as quickly as possible.
