Abstract: Device for transmitting movement to a speed indicator instrument and/or distance counter, particularly for bicyles, comprising a driving wheel driven by a tire of the bicycle and a transmission casing. The transmission casing has an input shaft on which the wheel is mounted, and an output shaft adapted to be connected by a flexible cable to the counter and/or indicator instrument, the input and output shafts being parallel and connected by a transmission system of the wheel and belt type. The input shaft is offset in relation to the median plane of the casing parallel to the input and output shafts in such a manner that the wheel projects only on one side of the casing.

Abstract: A front derailleur chain guide for a bicycle comprises a first branch and a second branch substantially parallel and joined to one another by a bridge connecting a portion of the top edges of each of the branches. An additional member is attached to the outer face of the first branch situated on the side where a smaller sprocket wheel is disposed. The additional member is fixed to the first branch and has elasticity such that it can move slightly away from the branch when the chain comes to bear against a portion of the additional member which projects forwardly of the first branch.
