Abstract

This invention, applicable to bicycles in general, consists of connectors for mounting on the crankset on the chain rings and on the arms of the cranks, their function being to reduce the ratio between the lever arm/effort with the arm of the load, because the invention creates new load points located inwards and closer to the fulcrum of the cranks, which will work in parallel with the original load point; we will therefore has the result of a greater tractive force with the same amount of effort applied to the cranks by the cyclist. The object of the invention is therefore to ease the job of the cyclist during pedalling by increasing the tractive force for equal muscular effort, resulting in greater efficiency. <IMAGE>
