Abstract: Abstract of DisclosureA transmission system provided for a bicycle, including a primary transmission sub-assembly having a set of rear sprockets, whose number of teeth, from one sprocket to the next sprocket in the ascending order, varies according to a ratio of the numbers of teeth that is greater than or equal to a value n such as n greater than 1. The invention also includes a control of the transmission system, as well as a bicycle that includes the transmission system and the control for same. The transmission system includes a single chain wheel for driving the chain, associated with a bottom bracket assembly, and a secondary transmission sub-assembly having at least two drive output ratios, whose ratio of the highest drive speed to the lowest drive speed is equal to a value R between 1 and n so as to introduce at least one intermediate transmission ratio between two successive sprockets.

Abstract: Abstract of DisclosureA rim structure for a bicycle wheel that includes, at its periphery, an annular channel designed to receive a tire, such channel being demarcated by an upper bridge devoid of openings with the exception of the valve opening, and two lateral flanges, such flanges having end butts for gripping the tire. The upper bridge has a narrow and recessed central rim well demarcated by a base and two lateral walls, the rim well being bordered by two bead seats that are oblique from the rim well towards the flanges. The invention is also related to a wheel having such a rim and a wheel equipped with a tire mounted without an air tube and having such a rim.
