  • Method and device for measuring the chain force in a bicycle
    Patent number: 7814800
    Abstract: A method is described for measuring the chain force (FK) in a drive chain (26) engaging on a body (20) that is rotatable around an axle (21) which is fixed in a frame (10) at least two connecting points (22, 23). The method comprises the steps of: measuring the reaction force (FL) between axle (21) and frame (10) at a first connecting point (22); measuring the reaction force (FL) between axle (21) and frame (10) at a second connecting point (23); and adding the two measured reaction forces (FL; FR).
